Is this ansi-c compliant?

hi

You can use pointer notation with an array in C:

int X[]={1,2,3};

int Y=*X[1];

But can you also use array notation with pointer(is it ansi c compliant)?

int i=3;

int *X=&i;

X[0]=10; //is this legal?

thank you

bye

why dont you just compile with gcc and use -ansi and find out?

Is function:

int X(i)
int i;
{
int j=16;
}

ansi c compliant?No,it ain't.But still,using 'cc -ansi X.c' doesn't give me any warnings about it,so I don't know why I should rely on -ansi switch to tell me whether something is ansi c or not

YES that is compliant and YES you can rely on gcc to tell you.

and "No, it ain't" isn't "grammatically compliant".
