C Program to demonstrate Bubble sorting. 

#include <stdio.h>
#include <conio.h>

void main()

C Program to demonstrate Employee Salary information using Arrays.
#include<stdio.h>
#include<conio.h>
main()
{
int i, empno[10], bs[10], net[10], bn[10], gr_sal=0;
clrscr();
printf("Enter EMPNO, BASIC salary, BONUS of 3 employees:");

{
int c, n, fact = 1;
clrscr();
printf("Enter a number to calculate it's factorial\n");
scanf("%d", &n);
