What else can I help you with?
Does a program exist with more than one main function?
No, it does not.
Can a function be called from more than one place in a program in c plus plus?
In C and C++, as well as in many (all?) languages, a function can be called from more than one place in a program. That's the purpose of functions - to encapsulate pieces of code that are needed in more than one place in the program.
What is the difference between simple program and function in C?
A function is a piece of code that has no or more arguments, that returns no or one value. A program is code that implements the function int main(int argc, char** argv). As such, a function and a program are the same, but the program also includes compiler directives to "include" other things, such as standard headers, i.e. #include .
What are the different modals and their uses?
Modals are special verbs that give more information about the function of the main verb...The main uses: PossibilityAbilityPermissionObligation
Explain the structure of c program with an suitable example?
Basic structure of a C program is /* Documentation section */ /* Link section */ /* Definition section */ /* Global declaretion section */ /* Function section */ (return type) (function name) (arguments...) void main() { Declaration part Executable part (statements) } /* Sub-program section */ (return type) (function name 1) (arguments...) (return type) (function name 2) (arguments...) . . . (return type) (function name n) (arguments...)

Which function calls itself repeatedly?
A main (or not-main) function can return a value to its caller.If the main function was called by the system, the return value means 0=success other=error-code.Function main can call itself, but it is not common.Example:int main (int argc, char **argv){int rc;if (argc>1) rc= main (argc-1, argv+1)else rc= 0;return rc;}
Difference Main functions and user defined functions?
main function in C programming language and almost in every other main language is the main function that launched after the program starts. It takes two arguments, pointer to the first element of a pointers array (arguments) and number of arguments.If you would write your own functions and link by telling the entry point to your program you would not be able to get arguments any more. There are some code running before actually main function is launched. That code prepares the argument data for main function.But it is possible to change main function to your defined function, but that would require more knowledge of how linker (ld) and for example objcopy utility works.Note: There might be a difference in GNU and Microsoft C/C++ versions.
Why do you have to use the return type for the main function in c language i mean to what does the main function have to return the value to?
It returns the value to the operating system or whatever process launched it. If you launched your program from a batch file then the batch file can detect this return value. If your program is spawned or launched by another program then the return value goes to that parent prgoram or process. One more thing is that you can write main() without the return type and it will be absolutely correct
How can you make a splash screen in c or c plus plus?
Many people use a modified version of the program's About dialogue window as a splash screen, but you can also create a dedicated splash screen window that contains an image of the company logo along with some program information. The choice is yours but ultimately a splash screen is nothing more than a window that is shown while a program loads in the background. When the program has loaded, the splash screen is closed automatically. The simplest method of displaying your splash screen is to use a program loader function. Typically this will be your program's main function or a function called from your main function. The program loader first loads and displays the splash screen, then loads the rest of your program in the background before closing the splash screen window and finally showing the main window. Some splash screens display progress information during the load sequence, thus your program loader should send messages to the splash screen and give time to the system to allow messages to be processed. This will increase the time it takes to load your program, but if the load process is lengthy to begin with, it is better to give some indication of the progress.
What is significance attached to the main function in C programming?
The main function in C++ is no different to any other function, other than it is the only required function; it defines the entry point of the application. The minimal main function (and therefore the minimal C++ program) is: #include <stdio.h> int main() { return(0); } The main function must always return an integer to the caller (even if not required by the caller). A return value of zero is usually used to indicate the program terminated successfully, however it is up to the programmer to decide what the return value actually means to the caller. It is common to return (-1) upon an unrecoverable error.
Define function in c program?
function is a self contained block or sub program of two or more statements which performs a special task when called.
Program defined function c?
function is a self contained block or sub program of two or more statements which performs a special task when called.
