Hello, this is kinda my first program. I would like to know how to clean the screen so only this code would stay in the console
Clrscr in C Function 'clrscr' (works in Turbo C compiler only) clears the screen and moves the cursor to the upper left-hand corner of the screen. If you are using the GCC compiler, use system function to execute the clear/cls command. Aug 06, 2015 Display message and use of clear screen. Use Dev C 5.7.1 It is best. If having trouble to find it, send me your email id i will send to you. Jun 17, 2004 If you're going to use Dev-C, go to the FAQ posted by Codeplug, and use OPTION 7 (Windows Console Option). It looks scary, but just cut and paste the function in your code, or put it in a header file (.h) and include that at the top (#include 'myheader.h'). Some non-Microsoft versions of C provide a clrscr function for clearing the screen in a DOS application. However, there is no Win32 Application Programming Interface (API) or C-Runtime function that will perform this function. Using the Clear method is equivalent invoking the MS-DOS cls command in the command prompt window. When the Clear method is called, the cursor automatically scrolls to the top-left corner of the window and the contents of the screen buffer are set to blanks using the. I use clrscr; to clear the screen but anyone knows how to clear the screen in any particular area. If you need that kind of control you should be using a console graphics library, or better yet, a full graphical application rather than the console.
I m also having trouble that when i make wrong ccalculation suchs as 5+5+, the program is looping the 5 + 5 calculation and ignores any input.

To clear your screen you can use system('CLS') - keep in mind this makes your program less portable though.
The reason you continuously loop when you enter bad input is because you're trying to accept a number, but are receiving a char, and your input buffer is overflowing.
Try '>flushing the input stream after you get the data you want.
Also, I would recommend using a switch rather than multiple IFs.

An I/O error occurred.
Examples
The following example uses the Clear method to clear the console before it executes a loop, prompts the user to select a foreground and background color and to enter a string to display. If the user chooses not to exit the program, the console's original foreground and background colors are restored and the Clear method is called again before re-executing the loop.
The example relies on a
GetKeyPress method to validate the user's selection of a foreground and background color.
