C Array: Exercise-15 with Solution

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
