BCA and B.Sc Programs - Programming in C Lab - Bharathiar University - Practical Program 8 - C Program to Find Factorial of a number using Recursive Function

Write a C Program to Find Factorial of a number using Recursive Function

Source Code

 #include<stdio.h>

long fact(int);

void main()

{

    int num;

    long fact_value;

    printf("Enter a number to find factorial: ");

    scanf("%d",&num);

    fact_value=fact(num);

    printf("Factorial of %d is  %ld",num,fact_value);

}

long fact(int n)

{

    if(n>=1)

        return(n*fact(n-1));

    else

        return(1);

}

Output

Enter a number to find factorial: 5

Factorial of 5 is  120

Enter a number to find factorial: 8

Factorial of 8 is  40320
