Code blocks error main must return int

To see this code, click on the + to the left of the Sources tab. The file will be named main. I recently have been working on a GLUT project in Code: Blocks. Everything in the code compiles correctly, yet every build seems to return the same result. I must admit, I can' t find the actual build command within code: : blocks. In the Project build options, Debug and Release, Linker settings, Linker libraries is listed only: - pthread. Declare " main" as " int main( ) " not " void main" and add " return 0; " before the final closing brace. _ RoRo_ Jan 26,, 6: 14 PM ^ what that guy said will fix your syntax and allow you to compile. 1) If finally block returns a value then try and catch blocks may or may not return a value. 2) If finally block does not return a value then both try and catch blocks must return a value. Please upload a file larger than 100x100 pixels; We are experiencing some problems, please try again. You can only upload files of type PNG, JPG, or JPEG. Note: When talking or reading about programming, you must consider the language background and the topic of the source.

    Error main return

    It is very rare to see a C+ + programmer use the words procedure or subprogram, this will vary from language to language. Customer Billing System Project is a simple console application designed to demonstrate the practical use of C programming language and its features as wells as to generate an application which can be used in any departmental store, shops, cafes etc. for billing to the customer. i recommend using MinGW as a compiler in Code: : Blocks. you can download the mingw32 version of code blocks. this is way easier as you dont have to do all the cofiguration when installing the ide all you do is select GNU C/ C+ + compiler as your default. Now that the hello( ) function is in a separate file, the function must be declared for main. Launch a plain text editor ( for example Notepad or Gedit), and add the following code. Line 21 should be int main( ) and at the end of your program you must return 0; / / obviously only if the program executed successfully Aug 1, at 9: 56pm UTC Athar ( 4466). Janu meri jaan, meh tere kurbaan. Janu meri jaa, meh tere kurbaan, meh tera tuh meri jaani saara hindustan. Meh tera tuh meri jane sara hindustan.

    So how is the author of these tutorials getting his code to run with the voids in place the nested int declare in place? Most compilers have extensions to allow a void return type for main, and of those compilers many also have those extensions enabled by default. Por alguna razón me da nostalgia. ponele un int en lugar de void al main( ) y antes de cerrar la llave que abre al main ponele return 0; Quedaria. It does not use too many C+ + features, but it uses enough to make this code non- compilable as C code. Either compile it as C+ + or convert it to C. The latter would require rewriting quite a few lines of that code. VC里报什么错? 两个编译器是有点不同, 但大多数时候, dev c+ + 可以编译的, vc里除了少数时候会报警告, 多数时候都会通过. Playing sound source code in C+ + This source code is not for playing songs or sound clips from your hard drive only to play sound by using windows function Beep( int dwFreq [ in], int dwDuration [ in] ). If you post code or log message to the forum, please use code tags: Click the " # " button in the new post editor ( see image) and post your code/ log between the two " [ code] [ / code] " words. This helps to distinguish between your text and the log and it shortens the posts. This might be a result of an incorrect extension.

    Make sure that your source file' s extension is. If the file has a. C extension, the compiler will interpret the source file as C code, not C+ +. cpp: In function ` int main( ) ' : cppfile. cpp: 3: too few arguments to function ` void myFunction( short int) ' cppfile. cpp: 7: at this point in file or cppfile. cpp: 3: too many arguments to function ` myFunction( ) ' cppfile. cpp: 7: at this point in file. Please put code tags around your code [ code] [ / code]. It makes it much easier to read your code. Dec 19, at 4: 32pm UTC. Try doing this: int main( int argc, char * * argv) { / / Code goes here return 0; } The return 0; returns a 0 to the operating system which means that the program executed successfully. Code Blocks I am trying to configure project in CODE: : BLOCKS according this tutorial: Playing with # include _ iostream_ using namespace std, int main( ) ( cout _ _ " Hello world! This content, along with any associated source code and files, is licensed under The Code Project Open License ( CPOL).

    When saving a project Code: : Blocks makes some additional changes to the cbp file that are not related to any configuration change in the project ( even when there is no change) and this makes version control software detect the files as modified. In ( hosted) C the main function must return an int ( C11§ 5. By declaring it with a return type of void, and not specifying any return value you invoke undefined behaviour. This means the compiler is free to return anything and in your case it turns out to be 16. Type: int If the function succeeds, terminating when it receives a WM_ QUIT message, it should return the exit value contained in that message' s wParam parameter. If the function terminates before entering the message loop, it should return zero. Functions 2: Void ( NonValue- Returning) Functions. Void ( NonValue- Returning) functions: Void functions are created and used just like value- returning functions except they do not return a value after the function executes. Code: : Blocks is a free C, C+ + and Fortran IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable. Finally, an IDE with all the features you need, having a consistent look, feel and operation across platforms. Objective- C is a strict superset of C; the additional functionality is obtained by linking to the Objective- C library when building using the standard GNU GCC Compiler.

    This makes setting up a new compiler very simple, as we can make a copy of the standard compiler and change the linker settings. Returning value from method having try- catch- finally blocks. Compile- time error: This method must return a result. This method must return a result of type int. 1 If the return type of the main function is a type compatible with int, a return from the initial call to the main function is equivalent to calling the exit function with the value returned by the main function as its argument; 11) reaching the } that terminates the main function returns a value of 0. The Secant Method is a root- finding algorithm that uses two initial approximations to start the iteration process. This root- finding algorithm uses a succession of roots of secant lines to better approximate a root of a function f( x) from to intial approximation x0 and x1. error: : ' main' must return ' int' in function ' int main( ) ' is there like to define objects in main. cpp and doing program in other file under sources. yeah i solve this just use a c+ + compiler like g+ + g+ + your project - o test and then. / test your project = the name of your text codes and 1 more note if u use g+ + and your file is in desktop go to file manager and go to desktop and click right on the desktop ( file manager) and click on open terminal and then boom finish it. Instead of # define coord = { 0, 0} ; put the following global variable COORD coord = { 0, 0} ; Since the COORD is a structure which contains the structure for holding x and y coordinates.
