Write a menu driven C program to perform the following operation on an integer array:
a) Display the sum of elements at even subscript position of array b) Display the sum of elements at odd subscript position of array
#include <stdio.h>
int main() {
int array[100];
int n, i, sum_even = 0, sum_odd = 0;
printf("Enter the size of the array: ");
scanf("%d", &n);
printf("Enter %d elements:\n", n);
for (i = 0; i < n; i++) {
scanf("%d", &array[i]);
}
int choice;
do {
printf("\nMenu:\n");
printf("1. Display the sum of elements at even subscript position\n");
printf("2. Display the sum of elements at odd subscript position\n");
printf("3. Exit\n");
printf("Enter your choice (1/2/3): ");
scanf("%d", &choice);
switch (choice) {
case 1:
sum_even = 0;
for (i = 0; i < n; i += 2) {
sum_even += array[i];
}
printf("Sum of elements at even subscript position: %d\n", sum_even);
break;
case 2:
sum_odd = 0;
for (i = 1; i < n; i += 2) {
sum_odd += array[i];
}
printf("Sum of elements at odd subscript position: %d\n", sum_odd);
break;
case 3:
printf("Exiting the program.\n");
break;
default:
printf("Invalid choice! Please enter a valid option (1/2/3).\n");
}
} while (choice != 3);
return 0;
}
