Answer 1

Malachite

int a = 0, int b = 0; is a wrong syntax

It should be

int a = 0, b = 0;

or it should be

int a = 0; int b = 0;

Answer 2

Ah thank you

Answer 3

Malachite

Also (char str) is not an array, it is a single character so

str[i] is wrong

there should be str1[i]

Answer 4

Yeah I'm running into that problem right now
