Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
For loop in C Programming.

Delete the element of Array

As we all know array is a collection of similar data type elements. In an array, only one variable is declared which can store multiple values. First will take the number of elements of an array from the user. Then will take the elements from the user for the array. And at last, we will delete the array element by asking the user with the help of C Programming Language.

Algorithm:-

Step 1. Initialize variable.

Step 2. Take size of array .

Step 3. Take elements of array.

Step 4. Take location to delete a element.

Step 5. Delete the element.

Step 6. Print result.

Step 7. End

Step 1. Initialize variable.

Step 2. Take size of array .

Step 3. Take elements of array.

Step 4. Take location to delete a element.

Step 5. Delete the element.

Step 6. Print result.

Step 7. End

Program:-

To Delete an element from the array

#include <stdio.h>
int main()
{
    //Declaring the variables
   int  x[100], loc, i, n;
   //taking size of array
   printf("Enter number of elements in array\n");
   scanf("%d", &n);
   //taking elements of array
   printf("Enter %d elements for the array \n", n);
   
   //for loop for input
   for (i = 0; i < n; i++)
   scanf("%d", &x[i]);
   //taking deletion position i.e. location for deleting element
   printf("Enter the location where you wish to delete element\n");
   scanf("%d", &loc);
   
   if (loc >= n+1)
      printf("Deletion not possible.\n");
   else
   {
      for (i = loc - 1; i < n - 1; i++)
         x[i] = x[i+1];

      printf("Output array:\n");
      for (i = 0; i < n - 1; i++)
         printf("%d\n", x[i]);
   }

   return 0;
}

#include <stdio.h>

int main()

{

//Declaring the variables

int x[100], loc, i, n;

//taking size of array

printf("Enter number of elements in array\n");

scanf("%d", &n);

//taking elements of array

printf("Enter %d elements for the array \n", n);

//for loop for input

for (i = 0; i < n; i++)

scanf("%d", &x[i]);

//taking deletion position i.e. location for deleting element

printf("Enter the location where you wish to delete element\n");

scanf("%d", &loc);

if (loc >= n+1)

printf("Deletion not possible.\n");

else

{

for (i = loc - 1; i < n - 1; i++)

x[i] = x[i+1];

printf("Output array:\n");

for (i = 0; i < n - 1; i++)

printf("%d\n", x[i]);

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

x[] = it will hold the elements in an array.

n = it will hold the number of elements in an array.
i = it will hold the integer value to control the array.
loc = it will hold the location for delete element size of the array.
