C Program to delete an element from array

C Program to delete an element from array at given position

#include <stdio.h>

void main()
{
    int arr[50], size, pos, i;

    printf("Enter number of elements: ");
    scanf("%d", &size);

    printf("Enter array elements-\n");
    for (i = 0; i < size; i++)
        scanf("%d", &arr[i]);

    printf("\nEnter postion to delete: ");
    scanf("%d", &pos);

    for(i = pos-1; i < size-1; i++)
        arr[i] = arr[i + 1];
    size--;

    printf("Array after deletion-\n");
    for (i = 0; i < size; i++)
        printf("%d ", arr[i]);
}

Output

Enter number of elements: 5

Enter array elements-
2
3
1

4

Enter postion to delete: 3

Array after deletion-

C Program to delete an element from array by given value

#include <stdio.h>

void main()
{
    int arr[50], size, pos, num, i;

    printf("Enter number of elements: ");
    scanf("%d", &size);

    printf("Enter array elements-\n");
    for (i = 0; i < size; i++)
        scanf("%d", &arr[i]);

    printf("\nEnter element to delete: ");
    scanf("%d", &num);

    // get the position of element to deleted
    for (i = 0; i < size; i++)
    {
        if (arr[i] == num)
        {
            pos = i + 1;
            break;
        }
    }

    for (i = pos-1; i < size-1; i++)
        arr[i] = arr[i + 1];
    size--;

    printf("Array after deletion-\n");
    for (i = 0; i < size; i++)
        printf("%d ", arr[i]);
}

Output

Enter number of elements: 5

Enter array elements-
