Object: To Print The Factorial of A Number Given by User. Source Code

This document contains the source code and output for 4 programs from a student's computer science lab assignment. The first program prints the factorial of a number input by the user. The second program prints even and odd numbers using a for loop and generates a multiplication table for a user-input number. The third is similar but uses a while loop instead of a for loop. The fourth program demonstrates incrementing and decrementing a variable.

Object: To print the factorial of a number given by user.

Source Code:

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

void main(void)
{
int d1, d2, d3= 1;

printf("Enter a number to calculate it's factorial: ");


scanf("%d", &d2);

for (d1 = 1; d1 <= d2; d1++)


d3 = d3 * d1;

printf("Factorial of %d = %d\n", d2, d3);

getch();
}
