Question

Say in main you globally declare a string of names (bobby, sally, suzie, joe) and their grades int (73,87,84,73) and you would like to sort their names in order(descending) with their following grade in C++ using a sort function. How would you do this using selection sort or either maxMin sort. Also, how would you sort their ascending ages to correspond with their names?

Explanation / Answer

#include <iostream>
using namespace std;

int main() {
string names[4] = {"bobby","sally","suzie","joe"};

int grades[4] = {73,87,84,73};

int minIndex;
string minValue;
int minGrade;

for(int i =0; i<4; i++)
{
  minIndex = i;
  minValue = names[i];
  minGrade = grades[i];
  
  for(int index = i+1;index<4;index++)
  {
   if(names[index] < minValue) // for sorting grades compare grades here
   {
    minValue = names[index];
    minIndex = index;
    minGrade = grades[index];
    
   }
  }
  
  names[minIndex] = names[i];
  names[i] = minValue;
  grades[minIndex] = grades[i];
  grades[i] = minGrade;
}


for(int i=0;i<4;i++)
{
  cout<<names[i]<<" "<<grades[i]<<endl;
}
return 0;
}

output:

bobby 73
joe 73
sally 87
suzie 84
