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

Make sure the variable is on the top part of the block, and in case you compile it with -ansi-pedantic, make sure it looks like this:

function() {
    int i;
    i = 0;

    someCode();
}
