16-09-2016
This is the C program code and algorithm for finding the factorial of a given number.
Aim:
Write a C program to find the factorial of a given number.
Algorithm:
Step 1: Start Step 2: Read number n Step 3: Set f=1 Step 4: Repeat step 5 and step6 while n>0 Step 5: Set f=f*n Step 6: Set n=n-1 Step 7: Print factorial f Step 8: Stop
Program code
#include<stdio.h> #include<conio.h> void main( ) { clrscr( ) int num,f=1; printf("Enter the number: "); scanf("%d",&num); while(n>0) { f=f*n; n--; } printf("The factorial is %d",f); getch( ); }
Output
Enter the number : 5 The factorial is 120
