Question

Write a c++ program that does the following:

in main()

1. prompts for a student's name (with spaces_

2. prompts for 3 grades

3. Calls a function to calculate the average of the 3 grades

- arguments must be passed by value

3. displays the student's name and average grade

- example: Fred Smith : 85.5

- the average should be a float displaying 1 digit of precision

Answer 1

Program:

#include <iostream>

#include<iomanip>

using namespace std;

float average(float g1,float g2,float g3); // function proto type

int main() {

char studentName[50]; // char array declaration

float g1,g2,g3; // integer variable declaration

cout << setprecision(1) << fixed; // set precision as 1

cout<<"Enter name of the student:";

cin.get(studentName,50); // Acept the name

cout<<"Enter 3 student grades:\n";

cin>>g1>>g2>>g3; // Accept three grades

cout<<studentName<<":"<<average(g1,g2,g3)<<endl; // calling function

}

float average(float g1,float g2,float g3) // called function

{

return (g1+g2+g3)/3; // return average

}

Output:
