C Program to Find Square Root of a Number using SQRT Function

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

int main() {
	
	int n;
	double v;
	
	printf("Enter a Number: ");
	scanf("%d",&n);
	
	v = sqrt(n);
	
	printf("Square Root of %d is %f",n,v);
	
}

The output of the above c program; as follows:

Enter a Number: 16
Square Root of 16 is 4.000000

C Program To Find Square Root of a Number Without Using sqrt

// C Program To Find The Square Root of a Number Without Using Sqrt
#include <stdio.h>
#include <math.h>

int main(){
    double num, root;
    
    // Asking for Input
    printf("Enter a number: ");
    scanf("%lf", &num);
    
    root = pow(num, 0.5);
    printf("The Square Root of %.2lf is %.2lf.", num, root);
    return 0;
}

The output of the above c program; as follows:

Enter a number: 16
