# prog-14 Write a flow chart and program to calculate factorial of an integer using for loop with function.

Algorithm:
Input:
1. n

Output:
1. fact

Method:
1.start
2.read n
3.write n
4.def fact(n) #calling function
5.stop

#called function before the main program
def fact(n)
    f=1
    for i in range(1,n+1,1)
     begin
      f=f*i
     end
    write"The factorial of given number is:",f

#program
def fact(n):
    f=1
    for i in range(1,n+1,1):
        f=f*i
    print("The factorial of given number is:",f)

#main program
n=int(input("Enter n number"))
print("n=",n)
fact(n)

Example:

Enter n number 4
n= 4
The factorial of given number is: 24
