 Posted: Fri Jul 25, 2008 6:31 pm Post subject: [Help, C++] Error, strings |
 |
|
Hey guys, I'm currently working on strings and I keep getting an error.
Here is my example code, im just using this so that i know what to do for further use for strings, i know this is just gonna print the string and it servers no purpose but i just needa know so i know what to do with other stuff
My code:
| Code: |
#include "iostream.h"
#include "stdlib.h"
#include "string.h"
int main
{
string mystring;
mystring == 'abcdef';
cout << mystring << endl;
return 0;
}
|
Error1: 'main' : looks like a function definition, but there is no parameter list; skipping apparent body
Error2: error C2015: too many characters in constant
for some reason the string in string mystring; doesn't highlight blue like when doing an int or char. is there another word for strings. also should i be declaring an int for main or is there something else, ty =]

1. Main is a function so you must put a () after it (ie. int main() )
2. single quote's mean character, while double quote's mean string.
3. == is a condition for equality, while = is for assignment.
edit:
4. #include <iostream> / #include <string>
5. std::string mystring; std::cout << ... or using namespace std (even tho its pointless for 2 things)
mystring = "abcdef";
should work.

Try:
| Code: |
#include <iostream>
#include <string>
int main() {
std::string mystring = "abcdef";
std::cout<<mystring;
return 0;
}
|
Btw, find a new tutorial, yours is outdated.

Well it uses bad methods such as including header files with "" instead of <> and using iostream.h and string.h (those are outdated). And try to avoid using system(""). Use this to pause:
| Code: |
std::cin.sync();
std::cin.get();

Ok , 1. I HAVE to do #include "iostream.h" Im using Visual C++ 2008 and you have seperate file that has #include <iostream> in it and iostream.h is the file name. It's not that im using iostream.h <.<
Also, i used
cin.sync();
cin.get();
and works great, thanks

Your welcome. But look, you don't have to use #include "iostream.h" in VC++ 2008. Just replace these lines of code:
| Code: |
#include "iostream.h"
#include "string.h"
|
with these lines of code:
| Code: |
#include <iostream>
#include <string>

Tried before and doesn't work =O
When I make my new project it has 3 folders, headers, resource files, and source files.
in headers i have to make 3 header files with all the headers and i write it there as #include <iostream>
but when i got my main source file, i have to write with " " to tell it to include that header file, then it reads what to include. idk why but thats how i have to do it <.< If i don't, i get compiling errors.

Lol. You need to learn how to use VC++. Always create empty projects. Hit Ctrl+Shift+N. Go to Win32 section. Choose Console. Put in a name and hit next, hit next again. Then select "Empty Project" and hit next. Now right click on the Source folder and click Add New File. Choose a cpp file and name it whatever you want. Then put in:
| Code: |
#include <iostream>
#include <string>
int main() {
std::string mystring = "abcdef";
std::cout<<mystring;
std::cin.sync();
std::cin.get();
return 0;
}
