C++ question

tdcnq2 The Mystic Llama · **Posted:** Wed 01-26-2005 9:10PM

Im new to C++ and Ive got a question, I dont know how to do it in C++, but how do i create a "sub" or "marker" that i can send the program to if certain things are true or input, such as

Quote:

person puts in a 1 for H

if H=1 goto "sub" something
else goto "sub" somethingelse

sub something

code
code
code
code
code

sub somethingelse

code
code
code
code
code

I used the sub command when messing with Easy UO scripting but apparently its not the same in C++, is there a command like this or am I just having wishful thinking? I cant seem to find anything like it in the book and would appreciate any light that someone could shed on the situation... I know I dont have all the correct symbols in there but thats the basic idea of what I'm trying to do...

Functions? They don't have to take arguments or return anything:

Code:

void something() {
  // code goes here
}

void somethingelse() {
  // more code
}

void main() {
  int h = 1;
  if(h == 1) something();
  else something();
  // more code after something() or somethingelse() returns
}

hmm thatll work for what I'm looking for, but is there a way to make it move to that part of the program and continue on instead of going to that function, doing it, then going back to the point it came from?

not that i know of.

you can put whatever code you want inside the fucntion to make it seem like its continuing on, but the way c++ works is to call a function to do something then return to the main function

Code:

#include <iostream>

int main()
{
    std::cout << "1 or 2: ";

    int num; std::cin >> num;

    if (num == 1)
        goto one;
    else
        goto two;

    one:
    std::cout << "you typed one";

    goto exit;

    two:
    std::cout << "you typed two";

    exit:

    return 0;
}

edit; reason u wont find it in a book is because its LAME

devil, shut up. you are useless. take your former roommate's dick out of your mouth and go eat a new dick, dickeater.

Code:

int main()
{
   if(h == 1)
   {
      do something;
   }
   else
   {
      do something else;
   }
   code after something and something else;
}

Same as using functions that genpfault showed. Do NOT use gotos.

i got another one, i cant get my if-else statement to output a message

Quote:

if (t==H)
cout << "Enter age (in calender years)\n";
else if (t==D)
cout << "Enter age in Human years: \n";

i need it to output one of these statements depending on what the user inputs for t, and then i need to request a particular input depending also on what t==, but when i have it setup like above it wont display either of the cout statements if an approptiate choice it pushed in, it simply ignores them and goes on

Can you post the rest of your code? The snippit you gave is rather ambiguous.

tdcnq2 The Mystic Llama · **Posted:** Thu 01-27-2005 6:32PM

I'll pm it to you

Just by looking at it... if you are expecting the characters 'D' and 'H' you need to put the single quotes around them. If they're actually variables forget what I just said.

ahh ok, got that fixed, one last question, what do i punch in to make it "clear" everything after the program starts, so it wont have all my other junk above the actual program??

nivlam · **Posted:** Thu 01-27-2005 10:07PM

on console?

system("CLS");

tdcnq2 The Mystic Llama · **Posted:** Thu 01-27-2005 11:56PM
