WebMethod 1: Using static variable in recursive main The idea is to call the main () function recursively, and with each call, print the next element from the series. To store information about the previous element printed, we use a static variable (Note that a global variable will also work fine). The following C++ program demonstrates it: OR WebStatic variables are created inside the code section especially maintained for global and static variables. This also means that unlike previously, instead of being created every time in program when the function is called. Static variables are created only once at the loading time of the program. WebStatic variables are allocated for the lifetime of the program. So, once it is allocated, it remains in memory until the program exits. Recursion takes place during the lifetime of the program. Therefore, the static memory would remain. As you can see in the example in the link above, count does not (because is cannot) get "reinitialized" or ... booz solutions 725m liberty it
