Question { Persistent, 7173 }

Generally variables are stored in heap memory. When he
variables are created in stack?

Answer

According to the C standard the storage will be.
1.variable with storage class 'auto' ie., local to the
function - in stack memory.
2.variable with storage class when 'extern' and 'static' are initialized stored in data segment otherwise found in bss.
3.variable with storage class 'register' in processor
register. But this register variable will be treated as
auto when there is no enough memory in the processor.
