Guessing game - setting levels

KrixisLV (19)
Hi! i was trying to write a guessing game and i had more or less finished it. but then i decided that i need an option for the user to choose a difficulty level. that tool is defined as an function (in the very bottom) but it always runs as the level EASY. can't really make out whats the problem. Hope you will excuse me for posting all the program but thats so you understand what am i doing.

I didnt read the whole thing. just a quick glance but in your choose level function you are using an assignment operator instead of checking for equality


it should be
1
2
3
4
5
6
7
 
if (x == 1)
{
    //do stuff
}

// ect

great! it worked! thanks :)

will have to look into this topic because right now i don't really understand why the computer didn't do what i wanted... why can't i use assignments?
