Difference between passing array, fixed-sized array and base address of array as a function parameter

I am confused about which syntax to use if I want to pass an array of known or unknown size as a function parameter.

Suppose I have these variants for the purpose:

void func1(char* str) {
    //print str
}

void func2(char str[]) {
    //print str
}

void func3(char str[10]) {
    //print str
}

What are the pros and cons of using each one of these?
