What is actual path of execution of a program?
how programs are executed? Let we take C, how a c program is executing.... A first step we have to install a particular software for a execution so here we are installing turbo c then open the bin folder after the installation ,you will find on executable file named TC.exe it will look like a command prompt that only executing your c program files and giving another executable file for your program as output. to check fisrt create any simple program and first compile it and see the bin folder you will find one file named filename.obj and then run that program and now you will find another file filename.exe,that is an output file.
How do you compile and run C programs on the Macintosh?
The first step is to install the XCode developer tools that comes with OSX. You can do this by looking on your OSX install disc. There should be a folder for optional installs, and a package for XCode. This will automatically install gcc, a C compiler, on your machine. Next, find the Console in the Utilities folder. It opens a UNIX shell. Move to the directory that your c file is in (you can find more information about UNIX elsewhere if you need to). Let's say your C file is named myfile.c. To compile it, type: gcc myfile.c This will compile your program, and name the compiled program a.out. To run it, type: ./a.out I hope that helps. Brina

A button is more correctly named a command button. It is an ActiveX control that is derived from a CWnd object. Command buttons can be resized, restyled, and can be assigned a caption and/or an image. Programmers can override command button methods (such as OnLButtonDown/OnLButtonUp and OnKeyDown/OnKeyUp) to invoke specific actions.
What are the six stages that typical c programs go through to be executed?
First of all the source code is get compiled and the object code is returned i.e.binary code(machine language).Then the Linker, a computer program that takes one or more objects generated by a compiler and combines them into a single executable program. Now when the program is executed then the .exe file is first loaded into the memory and then executed by the processor. In short the steps are: 1.Compilation 2.Linking 3.Loading 4.execution
