#include<stdio.h>
#include<conio.h>
int main()
{
	int a,c;
	printf("\n Enter any number");
	scanf("\n %d",&a);
	c=a*a;
	printf("\n Square of given no=%d",c);
	getch();
}

The above program takes an integer input from the user using scanf function and stores it in the variable a. The square of the number is calculated by multiplying the number with itself, and the result is stored in variable c.

Finally, the printf function is used to print the square of the number in the console window using the format specifier %d. The getch function is used to hold the console window until the user presses a key.

The program calculates the square of an integer number entered by the user and displays the result on the screen.
