Differences Between Local and Global Variables in C: Visibility: Local variables are visible only within the function where they are declared, whereas global variables are visible throughout the program. Lifetime: Local variables exist only while the function is executing, while global variables exist throughout the program’s execution.
global variables exist for the duration of the program. auto is now different in C and C++. auto in C was a (superfluous) way of specifying a local variable. In C++11, auto is now used to automatically derive the type of a value/expression.
