What C++ keyword is used to ensure a variable retains its value between function calls?

const
static
volatile
register

The correct answer is: static

A const keyword is used to designate a variable as constant and its value cannot be changed. This would not retain the variable's value between function calls. A volatile keyword is used for variables whose value can be changed by external factors and is used for multithreading purposes but would not ensure value between function calls. A register keyword is used to suggest to the compiler to store a variable in a register for optimization but does not ensure the value between function calls. A static keyword is used to retain the value of a variable between function calls and is the correct answer.
