Tell me what is the purpose of "register" keyword in C Language?
Submitted by: AdministratorThe keyword ‘register' instructs the compiler to persist the variable that is being declared , in a CPU register.
Ex: register int number;
The persistence of register variables in CPU register is to optimize the access. Even the optimization is turned off; the register variables are forced to store in CPU register.
