Develop a C program that calculates the final score and the average score for a student from his/her (1)class participation, (2) test, (3) assignment, (4) exam, and (5) practice scores. The program should use variables, cout, cin, getline(), type casting, and output manipulators. The user should enter the name of the student and scores ranging from 0 to 100 (integer) for each grading item. The final score is the sum of all grading items. The average score is the average of all grading items.

Answers

Answer 1

Answer:

#include <iomanip>

#include<iostream>

using namespace std;

int main(){

char name[100];

float classp, test, assgn, exam, prctscore,ave;

cout<<"Student Name: ";

cin.getline(name,100);

cout<<"Class Participation: "; cin>>classp;

while(classp <0 || classp > 100){  cout<<"Class Participation: "; cin>>classp; }

cout<<"Test: "; cin>>test;

while(test <0 || test > 100){  cout<<"Test: "; cin>>test; }

cout<<"Assignment: "; cin>>assgn;

while(assgn <0 || assgn > 100){  cout<<"Assignment: "; cin>>assgn; }

cout<<"Examination: "; cin>>exam;

while(exam <0 || exam > 100){  cout<<"Examination: "; cin>>exam; }

cout<<"Practice Score: "; cin>>prctscore;

while(prctscore <0 || prctscore > 100){  cout<<"Practice Score: "; cin>>prctscore; }

ave = (int)(classp + test + assgn + exam + prctscore)/5;

cout <<setprecision(1)<<fixed<<"The average score is "<<ave;  

return 0;}

Explanation:

The required parameters such as cin, cout, etc. implies that the program is to be written in C++ (not C).

So, I answered the program using C++.

Line by line explanation is as follows;

This declares name as character of maximum size of 100 characters

char name[100];

This declares the grading items as float

float classp, test, assgn, exam, prctscore,ave;

This prompts the user for student name

cout<<"Student Name: ";

This gets the student name using getline

cin.getline(name,100);

This prompts the user for class participation. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Class Participation: "; cin>>classp;

while(classp <0 || classp > 100){  cout<<"Class Participation: "; cin>>classp; }

This prompts the user for test. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Test: "; cin>>test;

while(test <0 || test > 100){  cout<<"Test: "; cin>>test; }

This prompts the user for assignment. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Assignment: "; cin>>assgn;

while(assgn <0 || assgn > 100){  cout<<"Assignment: "; cin>>assgn; }

This prompts the user for examination. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Examination: "; cin>>exam;

while(exam <0 || exam > 100){  cout<<"Examination: "; cin>>exam; }

This prompts the user for practice score. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Practice Score: "; cin>>prctscore;

while(prctscore <0 || prctscore > 100){  cout<<"Practice Score: "; cin>>prctscore; }

This calculates the average of the grading items

ave = (int)(classp + test + assgn + exam + prctscore)/5;

This prints the calculated average

cout <<setprecision(1)<<fixed<<"The average score is "<<ave;

Select the correct statement(s) regarding the signal-to-noise ratio (SNR).
A. SNR represents the ratio of transmit signal power over the noise power of all sources including thermal, impulse, IM, CCI, and crosstalk noise.
B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
C. the noise power, in the signal-to-noise ratio, occupies a narrow band in the frequency domain.
D. all of the above are correct statements.

Answers

Answer:

B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Explanation:

Sound can be defined as mechanical waves that are highly dependent on matter for their propagation and transmission. Sound travels faster through solids than it does through either liquids or gases.

Signal-to-noise ratio (SNR) is simply the ratio of signal power to noise power or the ratio of desired information to the undesired signal. SNR doesn't have a unit i.e it is a unitless quantity.

Generally, the higher the signal-to-noise ratio (SNR), the better would be the quality of a signal.

Additionally, a negative signal-to-noise ratio (SNR) in decibel form simply means that the signal power is lesser than the noise power.

Hence, the correct statement regarding the signal-to-noise ratio (SNR) is that the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Note: noise can be defined as an unwanted disturbance or undesired signal present in an electrical signal.

what was his beliefs?

Answers

A belief is an attitude that something is the case, or that some proposition about the world is true.[1] In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false.[2] To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white").[2]

There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Roderick Chisholm), as interpretive schemes for making sense of someone's actions (Daniel Dennett and Donald Davidson), or as mental states that fill a particular function (Hilary Putnam).[2] Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief (Paul Churchland) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have a belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief").[2][3]

Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?"; "Is the content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H2O part of the content of that belief)?"; "How fine-grained or coarse-grained are our beliefs?"; and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?".[2]

Military time is a 4 digit (base-10) integer with the following rules: The first two digits show the hour (between 00 and 23) and The last two digits show the minutes (between 00 and 59) There is no colon separating hours from minutes. Military time starts at 0000 in the morning and counts up When we get to the afternoon, we use 1300 for 1:00 PM and 2300 for 11:00 PM. When we get to midnight, the hour is 00 (not 24). TASK: Write a program that reads two times in military format and prints the number of hours and minutes between the two times (See example below). NOTE: Your program should consider the difference between the times IN THE SAME DAY. For example: The time difference between 2359 and 0000 is 23 hours and 1 minute (NOT 1 minute).Detailed Requirements Compose a written document (MS Word Document) describing your algorithm, feel free include a diagram if you like The program should prompt for two times separately, then print the duration of time between (see sample output below). The program should check the input for the correct military time format: . Make sure the hours are between 00 and 23. . Make sure the minutes are between 00 and 59 . If the validity check fails, it should print an appropriate error and prompt again. Your program should use io manipulators to produce military time with leading zeroes. e.g. 9 am should be printed 0900 (not 900). More points will be awarded to an implementation that can produce an accurate result regardless of the order of the inputs.
