C Language - finding the square root of a number

Among the computer programming languages, C is the most basic and also the most widely used language. C can be used not only for text documents but can also be used for various mathematical operations. Statistical as well as mathematical exercises ranging from basic addition, subtraction, cube root, square root and many polynomial powers can be created through this general purpose programming language. To get the square root of any number, the C script can be customized to code the logic which leads to this.


A simple C program allowing you to find the square root of a number.

#include <math.h>     
#include <stdio.h>     

int main(void)     
double x = 4.0, result;     

result = sqrt(x);     
printf("The square root of %lf is %lfn", x, result);     
return 0;     


  • In this code we make use of the sqrt function, more information available on :
