How Do You Program A Factorial In C++?

The factorial of a positive integer n is equal to 1*2*3*…n. You will learn to calculate the factorial of a number using for loop in this example.

Example: Find the Factorial of a Given Number.

i <= 4
fact *= i
1 <= 4
fact = 1 * 1 = 1
2 <= 4
fact = 1 * 2 = 2
3 <= 4
fact = 2 * 3 = 6
4 <= 4
fact = 6 * 4 = 24

Is it correct to detach the word factorial from the symbol?

It’s incorrect to detach the ! meaning “factorial” from the symbol preceding it, because it’s a modifier similar to a prime or a subscript and is not a punctuation symbol. In case you have a factorial followed by an ordinary symbol (not a relation or operation symbol), it’s good practice to add a thin space after it:

What is a factorial in math?
