    Answers:

    "World".when we use strcpy..contents of a are overwritten.



    here char *str2="hellO"
    str2 is pointer to a constant .And we are trying to change its content by strcpy().So it will give segmentation fault on c99.But on tc it will give world.Because tc has its own compilton scheme different from ansi c

    strcpy(a,b)
    strcpy is a string function.
    strcpy means we are copying one string into another string.
    b is treated as a source and a is treated as a source.
    so we are copying data from source to destination only in strings concept.
    so here "world" copying into pointer variable a(*a).

    What will be the output of the following program in UNIX OS with CC compiler and TC compiler?

    int main()
    {
    int i=5;

    }
    If any difference then Why it is difference?

    union u1
    {
    int i;
    char c;
    }u2;
    u2.i=32767;
    u2.c='a';
    now the i value gets replaced.
    If we want to know the data that is saved in the union..internally, without knowing what values that we are using in the prog.

    that is if just want to know whether a union currently holds an int or a char? If it is a combination of both int and char..we must know even that. and the memory locations at which this data is stored?
