Thread: functions in stack?

I have no ideas about the details of the functions in the main function layout in memory ,i only know tha t they are in the temp stack and I want to know some thing detail,please?
for instance:
#include <stdio.h>
int foo()
{ int array[3];
int i;
for(i=0;i<=3;i++)
array[i]-=3;
return 1;
}
int main()
{
foo();

return 0;
}
of course ,we know that the i have exceed the boundary of the array,and it sometime pointer to the call of the function foo(),so please explain the details ?

Nothing to do with C specifically, everything to do with your implementation.

What details are you after exactly? How the local scope variables in foo() are added/used on the stack? How the call stack looks after and before calling foo()?

There is no "standard" way to know if you've written outside the array in C. It can be done, but it's not trivial.
