Clickcharts no newline after enter8/3/2023 I recommend to compile with all warnings and debug info (so gcc -Wall -Wextra -g with GCC) and to learn to use the gdb debugger to understand the behavior of your program. You certainly cannot (portably) put a newline (or any other characater) into some input stream like stdin. If you are restricted to pure C standard functions, read carefully the documentation of scanf, and use its return count. I recommend using some library like readline or ncurses when that is the case.īTW, your use of select name is confusing (since select(2) was an old system call, today superseded by poll(2)). However, the standard input might not be a terminal (with redirections or pipelines) and you could check if it is one by using isatty(3) as isatty(STDIN_FILENO). In practice, if you are on some POSIX system (which I guess you are on), the terminal has a line discipline managed by the kernel. See also this answer to a question close to yours. New issue How to stop adding newline with Ctrl + Enter 6519 Closed hpivanov opened this issue on 1 comment on Mgsy closed this as completed on Mgsy added the type:question label on Sign up for free to join this conversation on GitHub. The C11 standard n1570 does not know about terminals or keyboard (so about the enter key), but only about standard streams. I'm using visual c++ 6.0 and i'm not really sure about the compiler thing.In pure standard C, what you want is probably impossible (and certainly ill-defined) and unclear. The program I wrote should compile and run as is and it'll put everything on one line. It's all doable and there may be a way to do it without using the methods listed above, but I can't think of one right now.īut make sure you really need to do this. Some type of redirection of stdin so it doesn't immediately echo to the screen.If you want to require the Enter key to be pressed between inputs, but don't want it echoes onto the screen, I imagine that you'd need something like: If that's all you care about, then the program I posted WILL work.īottom line, I think, is that if you use cin, it's going to echo whatever is typed to the screen. The main point of this is that i want my inputs all in one row. Then the program I posted definitely would not work for your needs. The program I posted, if it fits your needs, is the way to go, I think.ĥ (press enter) 1(press enter) 2(press enter) There's nothing that says that Enter needs to be entered between inputs unless you have a specific need for that. That is A standard way, not THE standard way. Import existing data or enter your graph data directly in the program. User-friendly data visuals omit the need for complex software learning. Time-saving templates designed for your workflow convenience. Getting started and adding your data is quick and easy. I'm to enter 3 numbers, standard way would be: Download ClickCharts and create your graph in minutes. You should be able to copy and paste my program verbatim and compile it without error using a compiler like g++. If you want to just have the user enter five numbers on a single line, separated by spaces, then hit Enter once: int num If each number is a single digit, that changes things considerably. Ctrl+Shift-Enter inserts new line afther that statement even if the statement is multiline. I was going to write up a response, but since that was just a GUESS of what the OP wanted, I'm going to hold off on that.Īlso, please note whether you are using "number" and "digit" interchangeably. It seemed a fairly odd request and I was puzzling over it. Enter is a delimiter), yet the newline would not be echoed onto the screen. Each Enter separated the next number from the last number (i.e. I thought the OP wanted the user to enter five numbers on one line and hit Enter five times. MyrtleTurtle might have interpreted in correctly and I didn't. To the OP, you should clarify what exactly you are looking for. There is no direct way, because scanf and friends are only a poor mans parser. I interpreted the OP's request differently. Do you mean that you don't want to have to press enter after each (one character) number is entered?
