Factorial C program,Algorithm,Flowchart

Q. Write a C program to find the factorial value of a number. Also write the algorithm and draw flowchart.
Ans.
/*c program to find out factorial value of a number*/ #include<stdio.h> #include<conio.h> int main() {
 int n,i,fact=1;
 printf("Enter any number : ");
 scanf("%d", &n);
 for(i=1; i<=n; i++)
    fact = fact * i;
 printf("Factorial value of %d = %d",n,fact);
 return 0; }

And Here is the Algorithm And Flowchart

Algorithm for calculate factorial value of a number:
[algorithm to calculate the factorial of a number] step 1. Start step 2. Read the number n step 3. [Initialize]
        i=1, fact=1 step 4. Repeat step 4 through 6 until i=n step 5. fact=fact*i step 6. i=i+1 step 7. Print fact step 8. Stop [process finish of calculate the factorial value of a number]
