WebThe call stack is a region of memory that is used to keep track of the order of function calls in a program. Each time a function is called, its return address and local variables are added to the top of the call stack. When the function returns, its return address is used to remove its entry from the call stack. If the call stack becomes too ... Web22 de jan. de 2024 · The call stack is composed of 4 function calls, and none of them run until the function returns 1. They sit on the stack until the last value is added, in this case 1. This is because each of the first 3 calls includes a reference to the next call on the stack! So, when num=4, the function returns 4*getFactorial (3). how to smudge prismacolor
