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 .

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");

C Program to implement Insertion sort Algorithm

In this tutorial, we will learn to create a C program that will do insertion sort using C programming.

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.
Creating and Using the user-defined function in C programming.

What is Insertion Sort?

In every programming language, the sorting of data is a very important factor. In C Language. Many different techniques for sorting are available to work with but in this tutorial, we will focus on the Insertion Sort Technique.

In this technique, the work is done by inserting the smaller number to the first position. i.e.

the first and second number is sorted if the number is big then it is moved to the right and if it is small the moves to the left.

Algorithm

The simple steps of insertion sort are as follows -

Step 1 - Let us assume if the element already sorted. Return 1.

Step 2 - Pick the next element store it separately in a key.

Step 3 - Now, compare the key with all elements in the sorted array.

Step 4 - If the element in the sorted array is smaller than the current element, 
         then move to the next element. Else, shift greater elements in the array 
         towards the right.
Step 5 - Insert the value.

Step 6 - Repeat until the array is sorted.

The minimum value 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. The index value of the array start’s from “0” if the array is having size 5 i.e. a[5] = { 1, 2, 3, 4, 5 } values can be stored in that array. Now the a[0] = 1 , a[1] = 2, a[2] = 3, a[3] = 4, a[4] = 5. On the array, we can do many operations with the help of the c language.

We will find the minimum size element with the help of conditional statements.

Output:-

The above program we have first initialize the required variable

a[] = it will hold the elements in a array1.
b[] = it will hold the elements in a array2.
c[] = it will hold the elements in a array3.

n1 = it will hold the number of elements of array1.
n2 = it will hold the number of elements of array2.
n3 = it will hold the number of elements of array3.

i = it will hold the integer value to control array using for loop.

Taking input from the user for array1 as well as array2 and merging them.

Printing merged array.

C Program to Insert an Element in an Array

In this tutorial, we will learn to create a C program that will Insert an Element in an Array using C programming.

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.
