This example will show you how to insert an element into an Array using C program.

The below insert function takes four arguments

void insert(int *a, int n, int i, int k)

*a – pointer to an array

n – size of the array

i – at what position of the array the element will be inserted

k – the element to be searched in array

Example

#include<stdio.h>

void insert(int *a, int n, int i, int k){
	int j,l;
	if(n<=i){
		printf("Insertion index must be less than size of the array");
		return;
	}
	for(j=n-2;j>=i;j--){
		a[j+1]=a[j];
	}
	a[j+1]=k;
	for(l=0;l<n;l++){
		printf("a[%d]=%d ",l,a[l]);
	}
}

main(){
	int i;
	int size=6;
	int a[6];
	for(i=0;i<size-1;i++){
		a[i]=i+100;
	}
	insert(a,size,5,135);
	return;
}

Output

a[0]=100 a[1]=101 a[2]=102 a[3]=103 a[4]=104 a[5]=135

Thanks for reading.
