using namespace std;
float division(int x, int y) {
   return (x/y);
}
int main () {
   int i = 50;
   int j = 0;
   float k = 0;
      k = division(i, j);
      cout << k << endl;
   return 0;
}

Output:

C++ try/catch example

#include <iostream>
using namespace std;
float division(int x, int y) {
   if( y == 0 ) {
      throw "Attempted to divide by zero!";
   }
   return (x/y);
}
int main () {
   int i = 25;
   int j = 0;
   float k = 0;
   try {
      k = division(i, j);
      cout << k << endl;
   }catch (const char* e) {
      cerr << e << endl;
