C++ code for finding the Square of a Number using Inline Function

This is the solution for finding Square of a number using Inline Function (T.U. 2067, 2068)

#include <iostream>

using namespace std;

class square
{
    int a, asqr ;
public:
    void geta();
    inline void squarea();
    void print();
};

void square::geta()
{
    cout << endl << "Enter a:" ;
    cin >> a ;
}

void square::squarea()
{
    asqr = a*a ;
}

void square::print()
{
    cout << endl << "Entered number(a)=" << a << endl << "Square of a=" << asqr << endl ;
}

int main()
{
    square s1;
    s1.geta();
    s1.squarea();
    s1.print();
    return 0;
}
