ratio_not_equal() in C++ with examples

Last Updated : 20 Mar, 2023

The ratio_not_equal is an inbuilt function in C++ STL that checks if two given ratios are not equal or equal. Syntax:

template < class ratio1_name, class ratio2_name > ratio_not_equal

Template Parameters: The function accepts two template parameters ratio1 and ratio2 which are to be compared. Return value: The function returns true if the ratios are not equal otherwise it returns false.

Time Complexity: O(1)

Auxiliary Space: O(1)

Program below demonstrates the function: Program 1:

CPP

// C++ program to illustrate the
// ratio_not_equal function
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
    typedef ratio<3, 9> ratio1;
    typedef ratio<1, 3> ratio2;

    // If both the ratios are not same
    if (ratio_not_equal<ratio1, ratio2>::value)
        cout << "Both ratio are not equal";
    else
        cout << "Both ratio are equal";

    return 0;
}

Output:

Both ratio are equal

Program 2:

CPP

// C++ program to illustrate the
// ratio_equal function
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
    typedef ratio<1, 2> ratio1;
    typedef ratio<5, 4> ratio2;

    // If both the ratios are not same
    if (ratio_not_equal<ratio1, ratio2>::value)
        cout << "Both ratio are not equal";
    else
        cout << "Both ratio are equal";

    return 0;
}

Output:

Both ratio are not equal
