C Number Programs

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;
}
