Return powf result to main function C Programming

Question

I'm trying to make a separate function that takes parameters x and y from the main function use use it in the powf, assign it to a variable 'result' and output it to the main function. Any help is appreciated

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

int  main() {

  float x = 5.5;
  float y = 3;
  float total = 1;
  int i;


  for( i=0; i <= y; i++ ) {
    total = total * x;
  }

  printf("total = %.3f\n",total);
  printf("Result of powf function is: %.3f\n", result);

  return 0;

}

float mathPow(float x, float y){

  result = powf(x,y);

  return result;

}

I have modified your code a bit

float mathPow(float x, float y){
  float result = powf(x,y);
  return result;
}
int  main() {

  float x = 5.5;
  float y = 3;
  float total = 1;
  int i;
  for( i=0; i <= y; i++ ) {
    total = total * x;
  }
  printf("total = %.3f\n",total);
  printf("Result of powf function is: %.3f\n", mathPow(x,y));
  return 0;
}

as you can see you did not called the function mathPow() in your main().

In order to execute the User Define functions you need to call them from your main()
