Recursive Functions - C++ Tutorial (Part 14)

Recursive functions are functions that calls themselves...

What happens in the example: fact(1) (returns 1, because of the if statement [if num == 1 return 1]) fact(1) also breaks the infinite loop, since it doesn't call fact()

2 * fact(1) (returns 2, since fact(1) returns 1; 2 * 1 = 2) 3 * fact(2) (returns 6, since fact(2) returns 2; 3 * 2 = 6) 4 * fact(3) (returns 24, since fact(3) returns 6; 4 * 6 = 24)
