Insertion sort in C program
Thursday, December 4th, 2008Here 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.
Insertion Sort Demo
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 29 | #include<stdio.h> 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++) { gotoxy(25,11+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(); } |

its help alot! Thanxxx nd Keep posting…!!
nice explanation…!!
thanxx
samjle nahi……….. simple language madhe sangat ja….. jay maharashtra
void main()
{
int a[20],temp,j,i,n;
clrscr();
printf(“enter no. of elements\n”);
scanf(“%d”,&n);
printf(“enter elements\n”);
for(i=1;i<=n;i++)
scanf("%d",&a[i]);
for(i=1;i<=n;i++)
{
for(j=1;ja[j+1])
{
temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}
for(i=1;i<=n;i++)
printf("\n%d",a[i]);
getch();
}
simplest
very nice demo.
Hi
cod you hellp me with some tasks? ?
What is gotoxy….? Can u hlep me plz…
very nice demo
#include
#include
void selection(int at J,int n)
{
int i,j,min,loc;
for(i=0;i<n-1;i++)
{
min=a[i];
loc=i+1;J<n.J++)
{
if(a[j]<min)
{min=a[J];
loc=J;
}
}
a[loc]=a[i];
a[i]=min
}
}
it helps me alot…tnx

thankx sir ye program to hmara run hi nahi ho raha tha but now i done it
Its very helpful for me,now every confusion has been finished…………..so thank you so so …………..much.

just WOWWW…
Your diagram and code doestnt match!
Program is good, but not diagram.

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++)
{
gotoxy(25,11+i);
scanf("\n\t\t%d", &A[i]);
}
for(i=1; i<N; i++)

j = i-1;
while(Temp=0)

}
thank u . . .Its is very useful . . .Keep posting more codes . .
i want print like this
.1
A B
2 3 4
C D E F . . . .like this any one help me write the coding for that
Sir. can you do a dutch flag problem using a insertion sort?
thanks
