Inside the for loop, we multiply the current value of result with the current value of our index i. Finally, we return the final value of the result. In order to get input from the user, remember to import the java.util.Scanner. If you'd like to read more about getting user input ...
Note: To test the program for a different number, change the value of num. Here, the number whose factorial is to be found is stored in num, and we check if the number is negative, zero or positive using if...elif...else statement. If the number is positive, we use for loop and...
A factorial can also be calculated with a while loop −n = 6; result = 1; i = 1; while i <= n result = result * i; i = i + 1; end This code is similar to the for loop method but uses a while loop instead.The execution in matlab command window is as follows −...
The weakness of this design from a Java perspective should be obvious: it does not allow us to select the algorithm we wish to use at runtime, which was a major design feature we were striving for. (I mean, after all, if our new program has different constraints, we should be able t...
submit button. The input box is used to get user input. The submit button is used to submit the form data. Followed by that is the PHP code to iterate for loop wherein all the logic is present, which we learned in the previous program. So now the same logic is used with an input...
# Code to find factorial on num # number num = 4 # 'fact' - variable to store factorial fact = 1 # run loop from 1 to num # multiply the numbers from 1 to num # and, assign it to fact variable for i in range(1, num + 1): fact = fact * i # print the factorial print(...
Using iteration and a loop in Java to calculate the factorial instead of recursion Although we presented the recursive answer to the question above, using recursion is not the best solution to the problem – especially when you are dealing with very large numbers. For instance, if you are tryi...
