The Program in C that will read an array of integers that should display the elements appearing at even and odd subscript positions separately is given below:
#include <stdio.h>
int main() {
int n, i;
printf("Enter the number of elements: ");
scanf("%d", &n);
int arr[n];
printf("Enter the elements of the array: ");
for (i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
printf("Elements at even position: ");
for (i = 0; i < n; i += 2) {
printf("%d ", arr[i]);
}
printf("\n");
printf("Elements at odd position: ");
for (i = 1; i < n; i += 2) {
printf("%d ", arr[i]);
}
printf("\n");
return 0;
}
Output:
Enter the number of elements: 4
Enter the elements of the array: 12
99
11
13
Elements at even position: 12 11
Elements at odd position: 99 13
Pro-Tips💡
This program prompts the user to enter the number of elements in an array, then uses a for loop to read the elements of the array.
After that, it uses two for loops to print the elements that are at even and odd positions separately.
The first for loop starts from 0 and increments the index by 2, so that it only prints the elements at even positions,
and the second for loop starts from 1 and increments the index by 2, so that it only prints the elements at odd positions.
It is worth noting that in C arrays are 0 indexed, so the first element is at position 0, second at position 1 and so on.
