How to program in Dev C on DEV C?

Because you're superimposing, it should be n+(n-1)+

So sum(n-1) should be called.

and sum(n--) means; It is equivalent to calling sum(n) first, and then assigning n-1 to n;

With superposition is not at all the same meaning.

If you use n--, it means that the assignment n=n-1 is completed, that is, the previous n also becomes n-1, for example, if n=3, n=n+(n-1) means n=3+(3-1).

If n=n+(n--) means n=(3-1)+(3-1).

n--means that the sum function is called to subtract one, and n-1 is to subtract one first, and then perform the sum calculation, which is equivalent to sum(--n).

Run the file-new-project command to bring up the new project dialog window. Select the Console Application option from the dialog box and click the OK button. The Save As dialog box is brought up, select a suitable save location, and click the Save button.

Then enter the ** area, enter the necessary programs in the area, and debug and run.

2. Then run the file-new-project command to bring up the new project dialog window.

<>4. Bring up the Save As dialog box, select a suitable save location, and click the Save button.

5. Then enter the ** area, enter the necessary programs in the area**, and debug and run.

6. Execute the execute-complete command and continue to debug and modify until there is no error.

1. Open Dev C++ and select "File --New --Source**" in the upper menu bar

2. Or press the Ctrl+N key combination, a blank source file will be created, as shown in the following figure:

<>4. Select "File --Save" in the upper menu bar, or press Ctrl+S to save the source file.

1. First open the Dev C++ software, click on the file menu at the top, and select the New Project option below.

<>3. Then the Save As interface will pop up, give the project a name, and select the type as dev.

4. In Dev C++, you can see the directory or noise, which means that the basic structure of the Windows Forms application has been created.

5. Open the file and change the name of the form at line 44.

6. Next, click on the Run menu at the top and select the Compile option in the drop-down menu.

7. After compilation, click the Run menu again, and then select the Run option in the drop-down menu.

8. You can see a windows form pop up.

Method steps.

1. Open the compiler, enter the following interface, click on the file in the upper left corner--- create a new --- project, create a new project, generally open the empty project, if you have other needs, you can choose other, you can also switch between C language and C++ language. It is easier to accept for beginners who have just learned C and C++.

2. If you are accustomed to working in the workplace, you can also clearly choose the default language, which can save a lot of energy for your programming. After clicking OK, a storage box will pop up, select the storage path of the **, generally do not store ** in the C disk (system disk), because the compiled ** may disrupt the normal operation of the system.

3 Next, there will be a compiler directly, which simplifies the process of creating a new file than vs, vc, because when you create a new project, the file path is put into your project path by default, if you want to change your file path in the later stage, you can directly cut to your desired path. The second ** annotates 1, compiles 2, runs 3, compiles and runs.

4 The compiler can also change the style of the compiler, click the tools --- compiler options in the menu bar, you can change the appearance, shortcut, spacing, font, background, etc. of the compiler. It is a more user-friendly function, also in the compiler interface, hold down Ctrl and roll the mouse wheel to change the size of the compiler interface, and it is more convenient to check whether there is an error in your own **.

5Next, click on compilation**, a dialog box will appear, asking to put the compiled ** in **, and at the same time, the compiler's data will appear at the bottom of the interface, as well as the annotation of error points. Similarly, the color of the annotation can also be modified via the compiler options.

Still don't use it, dev-c debugging is really a problem.

It is recommended that you use codeblocks.
