3. WHAT IS STATIC
• Static is a keyword in C++
• Can be used with the following:
• Variable declaration
• Class data member declaration
• Allocated storage on static storage area.
• Local variable gets storage on stack, whereas global
variables, arrays, pointers gets storage on heap.

4. DECLARING STATIC VARIABLE
• A variable is declared as static by writing the keyword
static in front of variable declaration.
• For example:
• static int a; //declaring static variable
int main()
{
int a;
}
int main()
{
static int a;
}
LOCAL /

8. SOME IMPORTANT POINTS ABOUT STATIC
VARIABLE:
• The default value of a static variable is always 0.
• The scope or lifetime of a static variable is not only within
the function but is within the whole program.
• Static variable is initialized only once i.e. it cannot be
reinitialized again and again when a function will be called
many times.
