C prog to find squareroot

Answer 1

To find the square root in C, you can use the sqrt function from the math.h library. Here’s a simple program:

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

int main() {
    double number, result;
    printf("Enter a number: ");
    scanf("%lf", &number);
    result = sqrt(number);
    printf("Square root of %.2lf is %.2lf\n", number, result);
    return 0;
}

This program prompts the user for a number, calculates its square root, and prints the result. Make sure to link the math library when compiling with -lm.
