Hey Guys,
I'm stuck with logical reason for initializing a struct variable. Please help..
Consider a struct defined this way..
struct foo
{
int a;
char *ptr;
};
in my function I declare a local variable of this struct.
void bar()
{
struct foo local_var[10];
...
...
}
do you suspect a initialization issue? do we need to initialize the
local array local_var[10] ? What's the best practice?
Thanks in advance.
Cheers,
Vadi

Yes. The array has random data.

Uh? Initialise it if you need.

This kind of initialization is done with memset(), so can use 0s to
avoid random data.
