C++ program to find Square of a Number using inline function

What are Functions ?

Function is a block of statements that performs some operations. All C++ programs have at least one function – function called “main()”. This function is entry-point of your program.

A function declaration tells the compiler about a function’s name, return type, and parameters. A function definition provides the actual body of the function.

Defining a Function : :

The general form of a C++ function definition is as follows:

return_type Function_Name( list of parameters )
{
//function’s body
}

• return_type : suggests what the function will return. It can be void, int, char, some pointer or even a class object.
• Function_Name : is the name of the function, using the function name it is called.
• Parameters : are variables to hold values of arguments passed while function is called. A function may or may not contain parameter list.
• Function body : is he part where the code statements are written.

Below is the source code for C++ program to find Square of a Number using inline function which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/* C++ program to find Square of a Number using inline function  */

#include<iostream>
using namespace std;

class square
{
   private:
        int n,r;
        float n1,r1;
        public:
                void input();
        void calc();
                void display();

};

inline void square::input()
{
        cout<<"Enter an integer :: ";
        cin>>n;
        cout<<"\nEnter a float no. :: ";
        cin>>n1;


}

inline void square::calc()
{
        r=n*n;
        r1=n1*n1;
}

inline void square::display()
{
        cout<<"\nSquare of integer [ "<<n<<" ] = "<<r<<"\n";
        cout<<"\nSquare of float [ "<<n1<<" ] = "<<r1<<"\n";
}

int main ()
{
        square s;
        s.input();
        s.calc();
        s.display();

        return 0;
}

OUTPUT : :

/* C++ program to find Square of a Number using inline function  */

Enter an integer :: 4

Enter a float no. :: 3.5

Square of integer [ 4 ] = 16

Square of float [ 3.5 ] = 12.25

Process returned 0
