Question

I need to convert the following into C++. The general idea is to create an application that can support 10 ID's and 10 grades. It needs to calculate the grade average of said ID, and determine if it is an below or above a certain average, ergo A or C.

string[10] studentIDArray
int[10] gradeArray
int averageGrade

for(int i = 0; i < gradeArray; i++)
{
averageGrade += gradeArray[i]
}

averageGrade = averageGrade / sizeof(gradeArray)
for(int i = 0; i < studentIDArray; i++){
if(gradeArray[i] > averageGrade)
{
Output: studentIDArray[i] gradeArray[i] grade is A
}
else
{
Output: studentIDArray[i] gradeArray[i] grade is C
}

}

Answer 1

#include <iostream>

using namespace std;

int main()
{
  // assign with default to test

string studentIDArray[10]={"101","102","103","104","105","106","107","108","109","110"};

// assign with default to test

   int gradeArray[10] = {1,2,3,4,5,6,7,8,9,10};
   double averageGrade; // since average is double
  
   for(int i = 0; i < 10; i++)
   {
       averageGrade += gradeArray[i];
   }
  
   averageGrade = averageGrade / (sizeof(gradeArray)/sizeof(gradeArray[0])); // divide by size
  
   for(int i = 0; i < 10; i++){
       if(gradeArray[i] > averageGrade)
       {
// print id grade grades got
           cout<<studentIDArray[i]<<" "<<gradeArray[i] <<" grade is A"<<endl;
       }
       else
       {
           cout<<studentIDArray[i]<<" "<<gradeArray[i]<<" grade is C"<<endl;
       }
   }
   return 0;
}
