[C++]Guess your number

I poked around with a different, lazier version of the number guessing game which does a lot of checking.

#include <iostream.h> #include <string.h> #include <math.h> int main(){ int counter=1, number=1, lasttry=1, looplimit=0; double increment=50, step=25; char choice[50]; cout << "Input a number (1-100): "; cin >> number; while(increment!=number){ lasttry=increment; if(increment>100||increment<1||looplimit>4){ cout << "You cheated, you gotta tell me the truth son!\n"; return 0; } cout << "You say the number isn't " << increment << ", so is it [H]igher or [L]ower than it? "; cin >> choice; if(choice[0]=='h' || choice[0]=='H'){ increment+=step; if(lasttry==increment){ increment++; looplimit++; } step/=2; step=floor(step); counter++; } else{ increment-=step; if(lasttry==increment){ increment--; looplimit++; } step/=2; step=floor(step); counter++; } } if(number==50){ cout << "The computer instantly guessed that your number was 50.\n"; return 0; } cout << "I guess the number you thought about is " << increment << ", and I WIN!\n"; cout << "It took the computer a total of " << counter << " tries to guess your number.\n"; return 0; }
