How to write a C Program to find the Square root of a Number using sqrt and without using the sqrt function with an example?
This program allows the user to enter any integer and then find the square root of that number using the math function sqrt(). Please refer to the built-in C sqrt and the C pow function.
#include<stdio.h>
#include<math.h>
int main()
{
double number, result;
printf(" \n Please Enter any Number to find : ");
scanf("%lf", &number);
result = sqrt(number);
printf("\n Square Root a given number %.2lf = %.2lf", number, result);
return 0;
}
C Program to find the Square root of a Number without using sqrt
This program uses the math function pow to find the square root of a number. As we all know √number = number½. For more topics, refer to the C programs article.
#include<stdio.h>
#include<math.h>
int main()
{
double num, result;
printf(" \n Please Enter any value : ");
scanf("%lf", &num);
result = pow(num, 0.5);
printf("\n Result of %.2lf = %.3lf", num, result);
return 0;
}
Please Enter any value : 3
Result of 3.00 = 1.73Also Read
