switch case question

okay im reading up on a c++ tutorial. i have no prior programming experience so far i now understand everything pretty well. i can use if statements and else and else if i used it to make some basic programs and have a decent beginner understanding. now the next section was switch case and i just read the explanation and am very confused. so you use it only for a integral value, so does this mean you would make a variable then use switch case to let the user type something in and make that variable equal to something and then have it execute code for what they chose. for instance have if they choose yes it does this you choose no it does this you choose nothing it does this etc. if i got that right please say so. i did that with if/else statements but switch case just confuses me. lets say i wanted if the user types in 1 to have it say hello and if the user types in 2 it says goodbye is this how you do it with switch case? also whats more commonly used switch case or if statements? this example question is just to give me an understanding i just randomly am trying it, its not serious. #include <iostream> using namespace std; int main() { int input; cout<<"Enter 1 for hello and 2 for goodbye.\n"; cin>> input; switch ( input ) { case 1: input == 1; cout<<"Hello!\n"; break; case 2: loadgame(); break; default: cout<<"Error, bad input, quitting\n"; break; } cin.get(); } actually as im trying to do this im confused on even what to do where do you define what each case should equal to execute the action? i just took the example from the tutorial and was trying to add in my own stuff and deleted some stuff. in case 1 is that what i do ?(probablly not but thought id try) i did not do the second part cause as i look at this i feel like its wrong lol. anyways thanks Hey

OH OKAY TY TRILLIAN AND TY PAIDLINE for your last two posts. your explanation cleared a LOT up in my head lol and your example paidline reinforced it. just one more question if i wanted to have something happen if its == 8 would i just do case 8? can it go out of order can i have like case 1 case 6 case 0?

yes, you would do "case 8:", it basically means "if your variable is equal to 8 then do the following". The order of the numbers is not important, as long as you have no duplicates (do not have two "case 5" for exemple).

okay thank you so much trillian i think i decently grasp this concept now. :). im about to go try and make a basic program to try and use switch case.

thanks again
