Given below is a C program to implement Insertion sort.
What is Insertion sort? Click here to read about it.
In Insertion sort the element is positioned at its proper place by inserting it and shifting the other elements to the right. The elements are sorted in increasing order of their position.

Example :
75 35 47 15 Pass 0 : 75 35 47 15 Pass 1 : 35 75 47 15 Pass 2 : 35 47 75 15 Pass 3 : 15 35 47 75Links that you may find important :

Code :
#include <stdio.h> #include <conio.h> void insert(int n,int a[]) { int i,j,k; for(i=1;i<=n;i++) { int temp=a[i]; printf("\nPass %d: ",i); for(k=0;k<n;k++) { printf("%d\t",a[k]); } for(j=i-1;j>=0;j--) { if(temp<a[j]) { a[j+1]=a[j]; a[j]=temp; } } } } void main() { int i,n,a[10]; clrscr(); printf("Enter no. of elements : "); scanf("%d",&n); printf("Enter the elements in array : \n"); for(i=0;i<n;i++) { scanf("%d",&a[i]); } insert(n,a);//call to function that performs the sorting printf("\nElements after sorting\n"); for(i=0;i<n;i++) { printf("%d\t",a[i]); } getch(); }Output :
Enter no. of elements : 4 Enter the elements in array : 75 35 47 15 Pass 1: 75 35 47 15 Pass 2: 35 75 47 15 Pass 3: 35 47 75 15 Pass 4: 15 35 47 75 Elements after sorting 15 35 47 75Note : The program above has been tested using TurboCPP.
