C Exercises: Delete an element at desired position from an array
15. Delete Element from Array
Write a program in C to delete an element at a desired position from an array.
Visual Presentation:
Sample Solution:
C Code:
#include <stdio.h>
void main() {
int arr1[50], i, pos, n;
// Prompt user for input
printf("\n\nDelete an element at the desired position from an array:\n");
printf("---------------------------------------------------------\n");
printf("Input the size of the array : ");
scanf("%d", &n);
// Input values for the array
printf("Input %d elements in the array in ascending order:\n", n);
for (i = 0; i < n; i++) {
printf("element - %d : ", i);
scanf("%d", &arr1[i]);
}
// Input the position to delete
printf("\nInput the position where to delete: ");
scanf("%d", &pos);
// Locate the position in the array
i = 0;
while (i != pos - 1)
i++;
// Shift elements to the left to replace the deleted element
while (i < n) {
arr1[i] = arr1[i + 1];
i++;
}
n--;
// Display the new list after deletion
printf("\nThe new list is : ");
for (i = 0; i < n; i++) {
printf(" %d", arr1[i]);
}
printf("\n\n");
}
Sample Output:
Delete an element at desired position from an array :
---------------------------------------------------------
Input the size of array : 5
Input 5 elements in the array in ascending order:
element - 0 : 1
element - 1 : 2
element - 2 : 3
element - 3 : 4
element - 4 : 5
Input the position where to delete: 3
The new list is : 1 2 4 5
