After entering the integrated development environment of Turbo C 2.0, the screen displays:

The top line is the main menu of Turbo C 2.0, the middle window is the editing area, the next is the information window, and the bottom line is the reference line. These four windows form the Turbo C 2.0 main screen. Later programming, compilation, debugging, and running will all be performed on this main screen. The following describes the content of the main menu in detail.

1.5.1 Main Menu

The main menu is displayed on the top of the Turbo C 2.0 main screen. The following content is displayed: file edit run compile project options debug break/watch has sub menus in addition to edit, you can enter the sub-menu of an item by adding the first letter (uppercase letter) to alt.

I. File menu

Press Alt + F to go To the File menu, which includes the following:

. Load (load)

Load a file and select a list using a DOS-like wildcard (for example, *. C. You can also mount a file with another extension, as long as the file name (or only the path) is provided. The key of this item is F3, that is, you only need to press F3 in the main menu to enter this item, instead of entering the File menu and then selecting this item.

. Pick (select)

Columns the eight files in the most recently loaded editing window into a table for the user to choose from. After selecting the file, load the program into the editing area and place the cursor in the Last modified area. Its hot health for Alt-F3.

. New (new file)

This indicates that the file is new. The default file name is noname. C. You can change the name when saving the disk.

Single quote'

2. When editing a file, Turbo C 2.0 also has the ability to automatically indent, that is, align the cursor position with the previous non-empty character. In the editing window, CTRL + ol is the control key for the automatic indent switch.

3. Run menu

Press Alt + R to enter the run menu, which has the following items:

. Run)

Run the file name specified by the project/project name or the file in the current editing area. If the source code after the previous compilation has not been modified, it runs directly to the next breakpoint (if there is no breakpoint, it runs until the end ). Otherwise, the system runs only after compilation and connection. The key is Ctrl + F9.

. Program reset (Program Restart)

Stop the current debugging and release the space allocated to the program. The hot key is Ctrl + F2.

. Go to cursor (run to cursor)

When debugging a program, select this option to run the program to the row where the cursor is located. The row where the cursor is located must be an executable statement; otherwise, an error is prompted. The hot key is F4.

. Trace)

When you call a sub-function defined by another user, if you use the trace into item, the execution bar will be traced to the sub-function for execution, and its hot key is F7.

. Step over (single-step execution)

Execute the next statement of the current function. Even if the user calls the function, the execution bar will not be tracked into the function, and its hot key is F8.

. User Screen)

Displays the results displayed on the screen when the program is running. The hot key is Alt + F5.

 

Iv. Compile menu

Press Alt + C to enter the compile menu, which has the following content:

. Compile to OBJ (compile and generate the target code)

Compile a C source file to generate the. OBJ target file, and display the generated file name. The hotkey is Alt + F9.

. Make EXE file (generate the execution file)

This command generates a. EXE file and displays the generated. EXE file name. The. exe file name is one of the following items.

1. project file name described by project/project name.

2. If there is no project file name, the source file is described by primary C file.

3. If neither of the above two items has a file name, it is the file name of the current window.

. Link EXE file (connect to generate the execution file)

Concatenate the current. OBJ file and the library file to generate the. exe file.

. Build all (create all files)

Recompile all files in the project and assemble and generate the. exe file. This command does not perform an out-of-date check (the above commands require an out-of-date check, that is, if the source file date and time in the current project are the same or earlier as the target file, refuse to compile the source file ).

. Primary C file (Master C file)

After the main file is specified in this item, in future compilation, if there is no project file name, compile the main c file specified in this item. If there is an error in compilation, the file is transferred to the editing window, whether or not the main c file is in the current window.

. Get info(Obtain information about the current path, source file name, source file size, number of errors in compilation, and available space ).

 

5. Project menu

Press Alt + P to enter the project menu, which includes the following:

. Project Name (project name) 

The project name has an extension of. prj, including the name of the file to be compiled and connected. For example, a program consists of file1.c, file2.c, and file3.c. To compile the three files into a file.exe execution file, you can create a file. prj project file with the following content:

File1.c

File2.c

File3.c

Put file. prj into the project name. during future compilation, the three source files specified in the project file will be automatically compiled separately. Then connect to the file.exe file.

If some of the files have been compiled into a. OBJ file but have not been modified, you can directly write the. OBJ extension. At this time, the connection will not be compiled but will only be performed.

For example:

File1.obj

File2.c

File3.c

File1.c will not be compiled and directly connected.

Note:

When each file in the project file has no extension, it is treated as the source file. In addition, the file can also be a library file, but the extension. Lib must be written.

. Break make on (abort compilation)

The user selects whether to exit make compilation before warining (warning), errors (error), fatal errors (fatal error), or link (connection.

. Auto dependencies (automatic dependency)

When the switch is set to on, the date and time of the source file and the corresponding. OBJ file will be checked during compilation; otherwise, the check will not be performed.
