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 The Square Root of 16.00 is 4.00.
