int - An integerfloat - A floating point numberchar - A characterchar * - An array of characters (more on this later... if you think about it, sounds kinda like a string doesn't it?)You've already seen int in the example before - it's the return value in the special main function (the entry point for every C program).
When declaring a variable, you must specify its type before the name and assigning a value.
Someone allowed a Pythonista into our beautiful C codebase!
Fix the bugs caused by missing types on lines 4, 5, and 6.
Here's the first variable for you:
int max_recursive_calls = 100;
