C Program to Insert an element in an Array
#include<stdio.h>
int main() {
int arr[30], element, num, i, location;
printf("\nEnter no of elements :");
scanf("%d", &num);
for (i = 0; i < num; i++) {
scanf("%d", &arr[i]);
}
printf("\nEnter the element to be inserted :");
scanf("%d", &element);
printf("\nEnter the location");
scanf("%d", &location);
//Create space at the specified location
for (i = num; i >= location; i--) {
arr[i] = arr[i - 1];
}
num++;
arr[location - 1] = element;
//Print out the result of insertion
for (i = 0; i < num; i++)
printf("\n %d", arr[i]);
return (0);
}Enter no of elements :5 1 2 3 4 5 Enter the element to be inserted :9 Enter the location 2 1 9 2 3 4 5Press any key to continue . . .
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
