C++

// CPP program to find
// the area of the square
#include <iostream>
using namespace std;

int areaSquare(int side)
{
    int area = side * side;
    return area;
}

// Driver Code
int main()
{
    int side = 4;
    cout << areaSquare(side);
    return 0;
}

Java

    {
        int side = 5;
        System.out.println(areaSquare(4));
    }
}
