ISO C90 forbids mixed declarations and code in C

Question

I declared a variable in this way:

int i = 0;

I get the warning:

ISO C90 forbids mixed declarations and code

Answer 1

I think you should move the variable declaration to top of block. I.e.

{
    foo();
    int i = 0;
    bar();
}

to

{
    int i = 0;
    foo();
    bar();
}
