Prerequisites

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.

Insert an 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 insert 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 insert a element.

Step 5. insert 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 insert a element.

Step 5. insert the element.

Step 6. Print result.

Step 7. End

Program:-

To insert an element in the array

#include <stdio.h>

int main()
{
//declaring variables
int array[100], position, i, no, value;
//taking size of array
printf("Enter number of elements in array\n");
scanf("%d", &no);
//taking elements of array
printf("Enter %d elements\n", no);
//for loop for input
for (i = 0; i < no; i++)
scanf("%d", &array[i]);
//taking insertion position i.e. location for inserting element
printf("Enter the location where you wish to insert an element\n");
scanf("%d", &position);
//value to be inserted
printf("Enter the value to insert\n");
scanf("%d", &value);

for (i = no - 1; i >= position - 1; i--)
array[i+1] = array[i];

array[position-1] = value;
//printing output
printf("Resultant array is\n");

for (i = 0; i <= no; i++)
printf("%d\n", array[i]);
return 0;
}

#include <stdio.h>

int main()

{

//declaring variables

int array[100], position, i, no, value;

//taking size of array

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

scanf("%d", &no);

//taking elements of array

printf("Enter %d elements\n", no);

//for loop for input

for (i = 0; i < no; i++)

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

//taking insertion position i.e. location for inserting element

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

scanf("%d", &position);

//value to be inserted

printf("Enter the value to insert\n");

scanf("%d", &value);

for (i = no - 1; i >= position - 1; i--)

array[i+1] = array[i];

array[position-1] = value;

//printing output

printf("Resultant array is\n");

for (i = 0; i <= no; i++)

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

return 0;

}

Output:-

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

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

no = it will hold the number of elements in an array.
i = it will hold the integer value to control the array.
value = it will hold the value to be inserted.

position = it will hold the location for the insert element of the array.

Taking input from the user in an array number of elements in the array

Taking input from the user in array elements in the array

Insert location for elements.

inert value.
