Can anyone help troubleshoot my C code?

#include <stdio.h>
#include <math.h>
#define MAXSIZE 10 // Maximum size of 1-D array

void arrayin(double X[], int n) {
for (int i = 0;i<n;++i){
scanf("%lf",&X[i]);
}
}
void arraypower(double X[], int n, double Z[],float p){
for (int i = 0;i<n;++i){
Z[i] = pow(X[i],p);
}
}
void printarray(int n, double Z[]){
for (int i = 0;i<n;++i){
    printf("   %f    ",Z[i]);
}

int main (void)
{
    double X[MAXSIZE]; // Array holds user’s input values
int n; // Actual array size
printf("Enter size of array: ");
scanf("%d", &n);
// actual code:

printf("Enter Array Values: ");
arrayin(X,n);
float p;
printf("Enter Power: ");
scanf("%f", &p);
double Z[n];
arraypower(X,n,Z,p);
printarray(n,Z);

}

}

Explanation / Answer

#include <stdio.h>
#include <math.h>
#define MAXSIZE 10 // Maximum size of 1-D array

void arrayin(double X[], int n) {
   int i;
   for (i = 0; i < n; ++i){
   scanf("%lf",&X[i]);
   }
}

void arraypower(double X[], int n, double Z[],float p){
   int i;
   for (i = 0;i < n; ++i){
   Z[i] = pow(X[i],p);
   }
}

void printarray(int n, double Z[]){
   int i;
   for (i = 0; i < n; ++i){
   printf("%0.2lf ",Z[i]);
   }
   printf(" ");
}

int main ()
{
   double X[MAXSIZE]; // Array holds user’s input values
   int n; // Actual array size
   printf("Enter size of array(less than 10): ");
   scanf("%d", &n);
   // actual code:
  
   printf("Enter Array Values: ");
   arrayin(X,n);
   float p;
   printf("Enter Power: ");
   scanf("%f", &p);
   double Z[n];
   arraypower(X,n,Z,p);

   printf("The elements of the Power Array are ::: ");
   printarray(n,Z);
   return 0;
}

//NOTE :: While using gcc we have to specify the math library exclusively at command line using -lm option
// else it gives an error saying pow is undefined

/****************** OUTPUT OF PROGRAM *******************
>> gcc -lm scr_c_program.c
>> ./a.out
Enter size of array(less than 10): 4
Enter Array Values: 10 20 30 40
Enter Power: 3
The elements of the Power Array are ::: 1000.00 8000.00 27000.00 64000.00
