when you make a second source file for your project, do you still have to write #include "<iostream.h>", "int main();" or anything else for it to run? what im saying is that if you write it in the first source file do you have to write it again in the second?
depends what the source file is, if it supports a class, depends what the class entails...
i think you can only have one main per program.
1st its either this #include <iostream> or #include "iostream.h". I have never seen ..."<iostream.h>" it like this but what you must do is create a header file and link every other .cpp file to you header file like so "header.h"Quote:

I hope this makes sense.
Good Luck!

and one more thing, how do you fix a parse error? or a syntax error? :confused:
i get all kinds and i dont know how to fix them! :eek:
that means your code is malformed and has lexical (is that the right word? i dont think so) things in it that dont make sense. check for missing semicolons ; missing and/or extra braces {} and parentheses ()Quote:

Like what kind because syntax errors range from misspellings to missing semicolons, etc.. You can also search MSDN.com for a better definition. Its a good library that I visit alot for finding definitions. Post some of those errors so maybe we can break them down 4 ya!Quote:

ok, here is my program (its pretty crappy, but im just tryin to make something):
here are the errors i got (ALL of them, dont bother helping if you don't wanna):Code:#inlcude <iostream>
#include <stdlib.h>
int main();
{
int answer; //variable
cout<<"What is 2+2?"; //Ya betta know that one!
cin>>answer; //here's where the value goes into our trusty variable, answer
if(answer==4) //if the user puts in 4, it will be correct.
{
cout<<"You are right. 2+2=4. Very good! You are very smart! Thank you for playing 2+2. Have a nice day.";
}
else
{
cout<<"You are wrong. Get outta here!"; //This happens if the answer is anything but 2
}
system("PAUSE")
return 0;
}
i put it in code so it would be easier to read.Code:1 C:\Dev-C++\Templates\Untitled1.cpp
undefined or invalid # directive
7 C:\Dev-C++\Templates\Untitled1.cpp
parse error before `{'
11 C:\Dev-C++\Templates\Untitled1.cpp
syntax error before `<'
13 C:\Dev-C++\Templates\Untitled1.cpp
syntax error before `>'
31 C:\Dev-C++\Templates\Untitled1.cpp
ANSI C++ forbids declaration `system' with no type
31 C:\Dev-C++\Templates\Untitled1.cpp
`int system' redeclared as different kind of symbol
328 C:\DEV-C++\include\stdlib.h
previous declaration of `int system(const char *)'31 C:\Dev-
C++\Templates\Untitled1.cpp
initialization to `int' from `const char *' lacks a cast
31 C:\Dev-C++\Templates\Untitled1.cpp
syntax error before `/'
i dont know why a lot of those errors are there. if ya wanna help, please do so!

NOTE: Look at the syntax errors/ misspelled, missing items you have. Does this help you better, my friend.
I hope this helps??
;)
i dont know how i spelled something like { wrong though...
EDIT
oops sorry i didnt look at your post well enough, i thought it was just a direct quote. thanx a lot again, it works!!! ill just have to be more careful next time...
Highlight the entire code in your program then press and hold alt and hit f8 to auto indent 4 ya! just a hint someone shared with me now i share with you.
BTW>>your_code
cjCode:#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
int answer; //variable
cout << "What is 2+2?"; //Ya betta know that one!
cin >> answer; //here's where the value goes into our trusty variable, answer
if(answer == 4) //if the user puts in 4, it will be correct.
{
cout << "You are right. 2+2=4.
"Very good!\n" //dont forget these \n = next line characters
"You are very smart!\n"
"Thank you for playing 2+2.\n\n"
Have a nice day.";
}
else
{
cout << "You are wrong. Get outta here!"; //This happens if the answer is anything but 2
}
system("PAUSE");
return 0;
}
:D
you didnt but you have to look one line ahead or one line behind where the error points to because that may be where the real problem lies. I have no idea why it alarms like that but hey "we just fix em, right?"Quote:

thanx again, it worked :)
U R welcome!
See bruces quote below, plz.
Later, my friend.
Good Luck, Blasta!

i know this is said a long time after you posted, but im wondering how do you make a header file?Quote:

Do you have MVC ++?

Whats the name of your software your using. e.g. Microsoft Visual C++? or what?Quote:
