How to use cbrt() function to get the cubic root of N in C

Answer 1

#include <stdio.h>     
#include <math.h>
 
int main(int argc, char **argv)
{
	double n = 27, rv;
	
	rv = cbrt(n);
	printf ("cbrt(%.1f) = %.1f\n", n, rv);
	printf("cbrt(-0.125) = %f\n", cbrt(-0.125));
	printf ("cbrt(1000.0) = %.1f\n", cbrt(1000.0));
  
    return 0;
}

// 3 * 3 * 3 = 27
// 10 * 10 * 10 = 1000
 
/*
run:
  
cbrt(27.0) = 3.0
cbrt(-0.125) = -0.500000
cbrt(1000.0) = 10.0
