DAA Lab program to perform counting sort

DAA LAB Program 5

Write a program to perform counting sort.

#include<stdio.h>

#include<conio.h>

void Counting_sort(int A[], int k, int n)

{

int i, j;

int B[15], C[100];

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

C[i] = 0;

for(j =1; j <= n; j++)

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

for(i = 1; i <= k; i++)

C[i] = C[i] + C[i-1];

for(j = n; j >= 1; j--)

{

B[C[A[j]]] = A[j];

C[A[j]] = C[A[j]] - 1;

}

printf("\nThe Sorted array is :\n");

for(i = 1; i <= n; i++)

printf("\t%d",B[i]);

}

void main()

{

clrscr();

int n,i,k = 0, A[15];

printf("\t\tCOUNTING SORT ALGORITHM\n\n\n\n");

printf("Enter the number of input : ");

scanf("%d",&n);

printf("\n\nEnter the elements to be sorted :\n");

for ( i = 1; i <= n; i++)

{

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

if(A[i] > k)

{

k = A[i];

}

}

Counting_sort(A, k, n);
