This C Program calculates Area of a Square based on the side of Square entered by the user.
Variables:1. side: (Datatype int) : to represent the side of square.
2. area: (Datatype int) : to store the result of the area of the square being computed.
Functions:printf() : is used to display something on the console/screen. Format specifier %d in printf function is used to display a int variable on scree. \n is used to add a newline
scanf() : is used to fetch data inputted by the user on the console/screen using keyboard. %d in scanf is indicates that inputted text is of type int.
Formula:Area of Square : (side)2

printf("Program to calculate Area of a Square : \n\n");
printf("Enter the side of a square : ");
scanf("%d", &side);
area = side*side;
printf("\n\nArea of square with side %d = %ld \n\n",side,area);
// getch();
}
Output:
Program to calculate Area of a Square :
Enter the side of a square: 20
Area of a square with side 20 = 400
Without using the variable area
