write c program to insert the values at the specific index in the array without using functions

Sure, here is a simple C program that inserts a value at a specific index in an array:

#include <stdio.h>

int main() {
    int array[100], position, i, n, value;

    printf("Enter number of elements in array\n");
    scanf("%d", &n);

    printf("Enter %d elements\n", n);
    for (i = 0; i < n; i++) {
        scanf("%d", &array[i]);
    }

    printf("Enter the location where you wish to insert an element\n");
    scanf("%d", &position);

    printf("Enter the value to insert\n");
    scanf("%d", &value);

    for (i = n - 1; i >= position - 1; i--) {
        array[i+1] = array[i];
    }

    array[position-1] = value;

    printf("Resultant array is\n");
    for (i = 0; i <= n; i++) {
        printf("%d\n", array[i]);
    }

    return 0;
}

This program first asks for the number of elements in the array, then the elements themselves. It then asks for the position at which to insert a new element and the value of the new element. It shifts all elements from that position to the right, then inserts the new element. Finally, it prints the new array.
