When a file contains instructions that can be carried out by the computer, it is often called a(n) executable file.
An executable file is a file that is used to perform various functions or operations on a computer. Unlike a data file, an executable file cannot be read because it has been compiled. On an IBM compatible computer, common executable files are .BAT, .COM, .EXE, and .BIN.
Watch out for executable files, such as '.exe', '.bat', '.pif', and '.scr'. If you download one of these you are, potentially, opening yourself up to anything on that file once you activate it. Try scanning it with a virus checker or any other software that is like it - just to be on the safe side.
Open compiler write a new C program, compile it using f9 and then run it. Once you run a program the .exe file is created under the output directory as set in the Options Directories. Executable file can be executed in two ways that are By typing the name of the executable file in the command prompt.
