C Program to Insertion Sort Using Array

This C program will show you how to short numbers at the time of Insertion.

This code implements insertion sort algorithm to arrange numbers of an array in ascending order. With a little modification it will arrange numbers in descending order.

Example:

/* insertion sort ascending order */

#include <stdio.h>

int main()

{

    int n, array[1000], c, d, t;

   

    printf("Enter number of elements\n");

    scanf("%d", &n);

   

    printf("Enter %d integers\n", n);

   

    for (c = 0; c < n; c++) {   

    scanf("%d", &array[c]);   

    }

   

    for (c = 1 ; c <= n - 1; c++) {   

        d = c;       

        while ( d > 0 && array[d] < array[d-1]) {       

            t          = array[d];

            array[d]   = array[d-1];

            array[d-1] = t;       

            d--;       

        }       

    }

   

    printf("Sorted list in ascending order:\n");

   

    for (c = 0; c <= n - 1; c++) {   

    printf("%d\n", array[c]);   

    }

   

    return 0;

}
