Multiple Counter Problem In For Loop

Question

Why is this not valid

for( int i = 0, int x = 0; some condition; ++i, ++x )

and this is

int i, x;
for( i = 0, x = 0; some c         


        

Answer 1

This is legal:

    for(int i = 0, x = 0; condition; ++i, ++x );

int x, int y is not a legal way of declaring variables;
