What Is The Difference Between Scope And Lifetime?

Shiladitya Munshi

05/07/2017 1 0

Scope of a variable is defined as the block of code from where we can refer or access it. On the other hand the life time of a variable is defined as the time in between allocating memory for it and relinquishing the memory from it. Let us have an example

void func1(void){

int x = 5;

// do other stuffs

}

void func2(void){

int y = 10;

func1();

//do other stuffs

}

In the above example scope of x is func1 and scope of y is func2. Now when we call func1from func2, then inside func, scope of y is ended but the life time of y still persists, because the memory for y is still not relinquished.
