Question

I'm having trouble determining the lines of code for 4-6

#include <stdio.h>

//function prototypes
void initializeArray(int size, int ids[]);
void printArray(int size, int * idPointer);

int main(void) {
// 1. declare an array of 5 integers called ids
int ids[1,2,3,4,5];
  
// 2. declare an integer pointer called arrayPointer and
// initialize it to point to the array called ids
int *arrayPointer = ids;

// 3. call initializeArray() function sending to it
// 5 for the size and the array called ids
intializeArray(5,ids[]);
  
  
  
// 4. add 3 to the value at where arrayPointer is pointing to
*(arrayPointer + 3);

// 5. add 5 to the value at 2 locations past
// where arrayPointer is pointing to

  
  
// 6. call printArray() function sending to it
// 5 for the size and arrayPointer

  
  
return 0;
}

// This function initializes an array ids of size "size"
void initializeArray(int size, int ids[]) {
int i;
for (i = 0; i < size; i++) {
ids[i] = i * 100;
}
}

// This function prints an array of size "size". The array is pointed at by idPointer
void printArray(int size, int * idPointer) {
int i;
for (i = 0; i < size; i++) {
// 7. finish the code for the printf() statement
printf("Element at index %d is %d\n", i);
}
}

#include <stdio.h>

//function prototypes
void initializeArray(int size, int ids[]);
void printArray(int size, int * idPointer);


int main(void) {
// 1. declare an array of 5 integers called ids
int ids[5];
  
// 2. declare an integer pointer called arrayPointer and
// initialize it to point to the array called ids
int *arrayPointer = ids;


// 3. call initializeArray() function sending to it
// 5 for the size and the array called ids
initializeArray(5,ids);
  
  
// 4. add 3 to the value at where arrayPointer is pointing to
*(arrayPointer) += 3;


// 5. add 5 to the value at 2 locations past
// where arrayPointer is pointing to
*(arrayPointer+2) += 5;
  
  
// 6. call printArray() function sending to it
// 5 for the size and arrayPointer
printArray(5, arrayPointer);
  
  
return 0;
}


// This function initializes an array ids of size "size"
void initializeArray(int size, int ids[]) {
    int i;
    for (i = 0; i < size; i++) {
        ids[i] = i * 100;
    }
}


// This function prints an array of size "size". The array is pointed at by idPointer
void printArray(int size, int * idPointer) {
    int i;
    for (i = 0; i < size; i++) {
        // 7. finish the code for the printf() statement
        printf("Element at index %d is %d\n", i,*(idPointer+i));
    }
}
