EDIT: I'm a huge fucking dumbass. For those who might one day find this thread by search, let this serve as a lesson: apparently, you need to declare variables in the beginning of a code block. Example below.

Code

#include <stdio.h>
int main()
{
    int x = 0;  //all I did was switch the first two lines
    printf("I hate Hello World. So boring... \n");  //all you need to do is make sure variables are declared at the top
    if(x==0){
        printf("wat?");
    }
    getchar();
    return 0;
}

Decided to get into a little C, being a native Python user. I literally just learned syntax today. Anyways, after typing some very basic code that SHOULD compile:

Code

#include <stdio.h>
int main()
{
    printf("I hate Hello World. So boring... \n");
    int x = 0;
    if(x==0){
        printf(".-.");
    }
    getchar();
    return 0;
}

I'm getting errors. For some background, I'm using MSVC++2010 Express, and I've named the file main.c rather than main.cpp...

Here are the errors:

Code

1>c:\users\arnav\documents\visual studio 2010\projects\omfg\omfg\main.c(5): error C2143: syntax error : missing ';' before 'type'
1>c:\users\arnav\documents\visual studio 2010\projects\omfg\omfg\main.c(6): error C2065: 'x' : undeclared identifier

I've been Googling the errors, but they are usually not found in simple programs such as this, and honestly, after Googling, I still have NO idea why it isn't compiling.

Thoughts?

[( ͡° ͜ʖ ͡°)]

So the first code is compiling, and the second one isn't?

Indeed. I think I've figured it out though, you need to declare variables at the beginning of code.

[Super Effective]

Both of those should compile successfully, I don't know why you're having trouble. I know some compilers force you to declare variables at the top, but I wasn't aware MSVC was one of them.

Also, changing the extension to .cpp instead of .c might fix that problem. You can still use C headers and use C functions in a .cpp file. You can also look into getting MinGW and using gcc under Windows.

c89 (what gcc considers ANSI) only allows variables declared at the beginning of functions. c99 (actual ANSI) doesn't have this requirement.
