Write a program that will insert an element at a particular position in an array.

Write a program that will insert an element at a particular position in an array.

Problem Name: Write a program that will insert an element at a particular position in an array.

 

Algorithm: Insert (LA, N, K, ITEM)

Step-01: Set J = K.

Step-02: Repeat Steps 3 and 4 while J ≥ K.

Step-03: Set LA[J+1] = LA[J].

Step-04: Set J= J – 1.

Step-05: Set LA[K] = ITEM.

Step-06: Set N = N + 1.

Step-07: Exit.

Code:

#include<stdio.h>

int main (){

    int LA[100],n,k,item,j;

    printf("How many elements: ");

    scanf("%d",&n);

    printf("Enter %d elements: \n",n);

    for(j=0;j<n;j++){

    scanf("%d",&LA[j]);

    }

    printf("Enter the location where you want to insert: ");

    scanf("%d",&k);

    printf("Enter the value you want to insert: ");

    scanf("%d",&item);

    printf("Array after insert: \n");

    for(j=n-1;j>=k-1;j--){

    LA[j+1]=LA[j];

    }

    LA[k-1]=item;

    for(j=0;j<=n;j++){

    printf("%d\n",LA[j]);

    }

    return 0;

    }
