Source Code:

1 2 3 4 5 6 7 8 9 10 11

#include <stdio.h> #include <math.h> void main (void) { double x = 0.0, square_root = 0.0; printf("Enter a number: "); scanf("%lf", &x); if (x > 0) square_root = sqrt(x); printf("SquareRoot = %2.2lf", square_root); }

Result:

Enter a number: 16 
SquareRoot = 4.00
