    Analyzing the memory layout for my sample program in Linux Environment.

    int test_g = 1; // Data or BSS ? Data section Right ?
    int test_h; // Data or BSS ? BSS section Right ?
    static int test_s = 1;
    static int test_q;
    int func1(bool a ,bool b)
    short temp;
    static int var_temp; // Stack or BSS ?
    return 0;
    int main(void)
    int m_var = 0; // Will be assigned in Stack section Right ?
    static int main_temp = 0 ; Which section Data or BSS ?
    m_var = func(true,true);// Will be assigned in Stack section Right ?
    return m_var;
    help me for the queries added as comments in 'C' Program.

    My Qs Is :

    What are all the sections shared during ,when the function call func1 made from the main?

    Generally every function call has its own stack.Other sections bss , data . text are shared between the multiple process or threads ?.
    will the heap shared ?

    Will the compiler assign the sections during the program compilation itself?
