A basic program to find the area of a square

The area of a square is simply the square of the side. So, you only need to write a program that receives a number as input, which is the side of the square, and returns that number squared, which will be the area of the square.

You didn't specify any language, so for example here's a C implementation that receives the side from the user and returns the area:

#include <stdio.h>

int main()

{

   double side, area;

   do{

       printf("Enter the side of the square (must be >0): ");

       scanf("%lf", &side);

   } while(side<=0);

   area = side * side;

   printf("The area is %lf", area);

}

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
