Oh good god, I don't even know where to begin:
-why do you need a goto statement? a loop would do just fine
-you are closing a nonexistent brackets
-42 is not the random number you generated
-and you also have improper brackets
-don't forget srand(time(0));
anyways, a simplified code would be like
int main() {
int guess,ans,try;
bool game = false;
try=0
char ag;
while(!game) {
if(try == 0)
ans = rand()%100+1;
cout<<"guess a number";
cin>>guess;
if(ans == guess) {
cout<<"you win! try again?y/n";
cin<<ag;
if(ag == 'y')
try=0;
else
game=true;
}
else
cout<<"wrong answer, try again"
if(tries==4)
game=true;
try++;
}
system("PAUSE");
return 0;
}this wont tell if the answer is too high or too low, but I'll leave that to you. Good luck.
