Question

Fix the code to print the "exact" result of the division of a/b (Pass by reference)

#include <iostream>

using namespace std;

void division (int& a, int& b, int& result) {
  
result = a/b;
  
}

int main () {
float a, b, result;
  
cin >> a;
cin >> b;
  
division(a, b, result);
cout << "result = " << result << endl;

return 0;
}

Answer 1

#include <iostream>

using namespace std;

// division function
void division(float a, float b, float &result)
{

    result = a / b;
}

int main()
{
    float a, b, result;

    cin >> a;
    cin >> b;

    division(a, b, result);
    cout << "result = " << result << endl;

    return 0;
}

/**
 * There was mismatch data type in division function it was defined as int but from main passing
 * the float data type
 * changed the data type in division function to:
 * void division(float a, float b, float &result)
 */ 

//OUT
