The clrscr issue in C

clrscr is a standard library function for C, not a standard library function for C++.

So for your second question, you can refer to the standard library functions under vc98.

Clear Text Mode Window Clear screen means to remove the text characters that were previously displayed, which is the same function as the clear screen in cmd, which is actually a shorthand for clear screen.

Clear screen letter copy

You can clear all or part of the results of the last run (depending on what you used the function for your program).

For example, if you run a program, if you can press alt+f5 to view the results under turbo c, you will have several results after running a few times, but if you only want to display the results of this run, you can use the clrscr() function after the main function (which can be used after the variable declaration).

Isn't there a DOS window after the compiled program is re-run? Delete all the words and pictures in it.

If you don't understand the DU words yet, I'll give you an example: start->run->cmd, jump out of a DAO dos window, and punch in it? Then hit enter, and when it's finished, you hit CLS and press enter, and you can see the effect.

The difference is that this method still leaves a few words, but with the clrscr function, it is black.

Clear your screen is to clear all the display information on the window you are currently using, and then your window will be empty.

Clear the screen, clear all the output of the output window.

Silver nitrate is added dropwise to a solution where Cl and CRO coexist, and the solution is yellow (the color of CROs) before dropping. After the dropwise addition of silver nitrate, a white precipitate of silver chloride is generated at the beginning.

Continue to add dropwise, when the CL reaction in the solution is complete, and then generate brick-red silver chromate precipitate with CRO. Continue to add silver nitrate dropwise until the CRO reaction is complete, and then centrifugal separation, the upper part of the solution disappears yellow, and the lower part precipitates yellow (a mixture of silver chloride and silver chromate).
