How To Save C Program? - Programming Line

Following are the steps to write and save a C program:

Open C editor and Create new file

Open the drive in which Turbo C is installed.
Open the bin folder.
Click on the turbo C icon.
C editor will open.
Press ctrl+F to open the file menu.
In the file menu scroll down using down arrow on the keyboard to the new option in the file menu and press enter.
New file will open.

Follow these steps to save new file

Press ctrl+f on the keyboard to open file menu.
Scroll down to save the option of the file menu using the down arrow key of the keyboard and press enter.
This will open the save file dialog box.
Pressing F2 key on the keyboard will also open the save file dialog box of the Turbo C.
Save file dialog box will have a textbox to enter the name of the C file.
The textbox contains the path where the file will be saved.
User may change the path where the file will be saved.
Enter the name of the file just before the extension .cpp.
If “noname ” is coming before .cpp then remove “noname” and type the name of the program.
Length of the file can be of six characters.

Compile saved program

To compile the saved program press Alt+F9 on keyboard.
When compilation completes a dialog box will open which will show number of errors, warnings and lines in the program.

Run compiled program

To run a C program press ALT+F5 from the keyboard.

Another way of creating and saving C file

In this you will learn to write C program using notepad++ and develop executable files using GCC compiler.

Following are the steps:

Creating and saving C program

Open Notepad++ text editor, when the Notepad++ text editor is open, write following C program in it.

#include <stdio.h>
{
     printf(“This is your first program”);
     return 0;
}

This is your first C program.
Save the file by clicking on the File menu of the Notepad++.
The File menu contains two options: first, Save and second, Save as.
Save option is used to save the Notepad++ file at the user desired location.
Name of the file must have a .c extension.

Open the command prompt by writing Run in the search box of startup.

When the Run window open type cmd.
This will open the command prompt.
At the command prompt write the command to move to the folder containing the Turbo C.
If you are in some other directory than type cd..
cd.. will take you out from the current directory.
When you want to move into a certain directory than type following command at the command prompt:
cd <name of the directory>
Example: cd alpha
This command will move you into the directory alpha.
Thus , appropriate use of cd will move you into the folder containing turbo c.
When you are in the correct directory type the name of the file having .c extension and enter.

Compile the C program

GCC compiler is used to compile the saved program and obtain an executable file.
To obtain the executable file of saved program type the following command at the command prompt.
gcc <name of the program>.c -o <name of the program>.exe
This command will create an executable file.

Run the executable file.

To run the executable file type the name of the file having .exe extension after ./

For example:

. / hello.exe

Output will be displayed on the terminal like this:

This is your first program.

Key terms

Source file: source file is a file having C programming language.

- Source file extension .c
- .c extension differentiate this file with other text files.

Executable file: Executable files are executed by computers.

- Executable files are not human readable.
- Executable file does not contain text, instead it has a combination of numbers and characters. These are called executable code.
- To run a C language program its source code needs to be translated into executable code or object code.
- The compiler of C language converts source code into executable code.

Compiler: A compiler is also known as translator.

GCC compiler is used to translate the source code into executable code.
Executable code is not human readable.

Online C compilers

If a programmer is not able to install a C compiler on its personal computer due to computer hardware limitation in this case, the programmer may use a compiler available online. Following is the list of compilers available online:

Online GDB online C compiler:

Online GDB is an online IDE available to compile C programs. It provides an online editor to create C programs and supports GCC to compile C language source code.

To save the C program in the Online GDB editor it has a save button. When a user clicks on the save button editor asks the user to create an account. When an account is created the developed C program is saved in that particular account by giving a specific name and clicking on the save button.

CodeChef online C Compiler

CodeChef is an online compiler for C programs.

To save C program users will have to create an account.

Repl Online C Compiler

Repl.it is a robust C compiler. It has an IDE to develop C source code and generate its corresponding object code.

To save the C program in the Online Repl.it editor it has a create button. When a user clicks on the create button editor asks the user to create an account. When an account is created the developed C program is saved in that particular account by giving a specific name and clicking on the create button.

OneCompiler

OneCompiler is an online C compiler that is used to develop programs in C language code.

In OneCompiler user will have to create a personal account. When the account is created successfully than whenever the user will develop a C program it will automatically be in the user personal account.
