Using namespace std Write a C program that continuously req

Using namespace std ;

Write a C++ program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should print an appropriate message informing the user that an invalid grade has been entered, else grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. Run the program and verify it using the appropriate data.

Solution

#include <bits/stdc++.h>
using namespace std;

int main(int argc, char const *argv[])
{
   int ch;

  
   int total=0;
   int count=0;
  
   do
   {
       cout<<\"Enter grade\ \";
       cin>>ch;

       if(ch<0||ch>100)
       {
           cout<<\"invalid grade has been entered\ \";
          
       }
       else
       {
           total+=ch;
           count++;
       }
   }while(ch!=999);  

   cout<<\"Avearge is \"<<(float)total/count<<endl;
  
   return 0;
}
