exercise functions 2 (pow())

#include <stdio.h>//library for printf and return 0
double pow(double X, double Y);// This will tell the computer to square X (base) by however many times Y (the exponent). Although I don't really need it, because of the math.h library.
int main(void){
  double X;//assign the variables as doubles
  double Y=2; // because the lab asks for the number to be squared I set the exponent to 2.
  double sum;
  printf("Please Enter Variables: ");
  scanf("%lg",&X);
  sum= pow(X,Y);// because of the math.h library, the computer will take the number that the user inputs and plug them into the equation.
  printf("This is the answer: %g",sum);//don't need to scanf sum because the sum is already defined to the equation pow(X,Y).
  return 0;
