C programming

C programming language: To easily learn C language you must start making programs in it. As you may already know that to develop programs you need a text editor and a compiler to translate a source program into machine code which can be executed directly on a machine. Dev C++ IDE is a good choice, so if you are not having it installed on your computer then download Dev C++ compiler.

Compiling and executing C programs

Now you have the tool to create programs, if you wish to look at some example codes then see C programming examples. Now I will explain to you how to compile and run your programs. You may be using a different compiler or operating system. I will explain to you how to use Dev C++, GCC and Turbo C compiler.

Dev C++
1. Create a new file (Ctrl+N).
2. Write the code.
3. Press Ctrl+F9 to compile the program. If there are any compile-time errors then fix them.
4. Press Ctrl+F10 to run the program.

Compiling and running C programs in GCC compiler
1. Save the code in a file say “hello.c” (quotes for clarity).
2. To compile open terminal and type “gcc hello.c”.
3. To execute type “./a.out”.

You can also specify the output file name as:
gcc hello.c -o hello.out
hello.out is the name of the output file.

Turbo C compiler:
1. Write your code to a file and save it.
2. Compile by pressing Alt + F9.
3. Execute by pressing Ctrl + F9.
4. For viewing output of the program, press (Alt + F5).
