"syntax error : missing ';' before '{'" in c++ project with precompiled header -


when trying compile simple c++ project, following error:

syntax error : missing ';' before '{'

i did research. compiler doesn't allow declaration of variables inside of loop, inconvenient me. if declare loop variables before loop, error disappears.

this c++ project "stdafx.h" precompiled header.

is compiler behavior (c89) enforced fact i'm using precompiled header or did scr**ed config in past ? there way of circumventing befavior ?

p.s. i'm using visual studio 2012 on windows 7 64-bit;

code samples:

  1. error on first line

    for (int idx = 0, int = 100; idx < (sizeof(antestscores) / sizeof(int)); i++, idx++) {     antestscores[idx] = i; }

  2. this compiles 

    int idx; int i; (idx = 0, = 100; idx < (sizeof(antestscores) / sizeof(int)); i++, idx++) {     antestscores[idx] = i; }

go with

for (int idx = 0, = 100; idx < (sizeof(antestscores) / sizeof(int)); i++, idx++) { antestscores[idx] = i; }

this declares two variables of type int in first statement of for loop.

the reason works , other attempt doesn't follows:

each declaration statement has separated each other ;, same ; used separate parts of for(;;) loop's header tried around using ',' operator. didn't work due syntax error
