Here is the program to sort the given integer in ascending order using insertion sort method. Please find the pictorial tutor of the insertion sorting.

**Logic :** Here, sorting takes place by inserting a particular element at the appropriate position, that’s why the name- insertion sorting. In the First iteration, second element A[1] is compared with the first element A[0]. In the second iteration third element is compared with first and second element. In general, in every iteration an element is compared with all the elements before it. While comparing if it is found that the element can be inserted at a suitable position, then space is created for it by shifting the other elements one position up and inserts the desired element at the suitable position. This procedure is repeated for all the elements in the list.

If we complement the if condition in this program, it will give out the sorted array in descending order. Sorting can also be done in other methods, like selection sorting and bubble sorting, which follows in the next pages.

**C program for Insertion Sort:**

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | #include void main() { int A[20], N, Temp, i, j; clrscr(); printf("\n\n\t ENTER THE NUMBER OF TERMS...: "); scanf("%d", &N); printf("\n\t ENTER THE ELEMENTS OF THE ARRAY...:"); for(i=0; i<N; i++) { scanf("\n\t\t%d", &A[i]); } for(i=1; i<N; i++) { Temp = A[i]; j = i-1; while(Temp<A[j] && j>=0) { A[j+1] = A[j]; j = j-1; } A[j+1] = Temp; } printf("\n\tTHE ASCENDING ORDER LIST IS...:\n"); for(i=0; i<N; i++) printf("\n\t\t\t%d", A[i]); getch(); } |

i need a unique & short program using insertion sort ?? can you help me ?

hii..i want to know the meaning of why we use j=j-1 after assigning temp to a[i] in insertion sort..please explain it as soon as possible my mail id is gchetna30@gmail.com.

main()

#define size 10

{

int arr[size],i,j,item;

printf(“\n enter the element in array”);

for(i=0;i<size;i++)

scanf("%d",&arr[i]);

for(j=0;j<size;j++)

{ item=arr[i];

for(i=j-1;item=0;i–)

{ arr[i+1]=arr[i];

arr[i]=item;

}}

thnxx.

i understood insertion stood.

sir,i want to know what is use of gotoxy()?

multy way tree

#include

#include

void main()

{

int a[20],k,n,i=0,j=0,t=0;

clrscr();

printf(“no of of elemts”);

scanf(“%d”,&n);

printf(“enter %d values”,n);

for(i=0;i<n;i++)

scanf("%d",&a[i]);

for(i=1;i=1;j–)

{

printf(“i=%d j=%d %d %d”,i,j,a[j],a[j-1]);

if(a[j]>a[j-1])

break;

else

{

t=a[j];

a[j]=a[j-1];

a[j-1]=t;

}

} printf(“\n”);

} printf(“\n”);

for(i=0;i<n;i++)

printf(" %d ",a[i]);

getch();

}

THE ABOVE CODE REPRESENTS WHICH SORTING TECHNIQUE????

DOES IT REPRESENT INSERTION SORT????

m confused in insertion sort …..when comparison is done and 1st pass completes then how elements compare with all the previous elements there is no loop ……pls explain…..

Well explained. I assume there is one error in the code during runtime. Changed below code.

while( j>=0 && Temp<A[j] )

{

A[j+1] = A[j];

j = j-1;

}
