Question

I wrote in C function:

    void func(int count,bool infini){
//...
}

I try compile this code with Code Blocks, (GCC) spike:

“expected declaration specifiers or ‘…’ before bool”

.
Where is bug?

Chances are that you are compiling in C mode. C does not have bool. Use int instead or include stdbool.h to get a #define of bool (only C99) or create a typedef / #define yourself (if your compiler doesn’t have or you don’t want to use stdbool.h. But GCC provides this header).

Alternatively in C99 code you can use _Bool instead (which is a keyword in C99, much like bool is to C++), but take in mind that C99 is not widely supported.
