user-input

In c, I can use newline delimeter ([^\n]) with scanf. Using which I can store the line. Similarly for cin, I can use getline. If I have to store a paragraph, I can simulate the functionality using my own special char delimiter like [^#] or [^\t] with scanf function in c. char a[30]; scanf("%[^\#]",a); printf("%s",a); How to achieve the similar functionality with cin object in cpp. istream.getline lets you specify a deliminator to use instead of the default '\n' : cin.getline (char* s, streamsize n, char delim ); or the safer and easier way is to use std::getline . With this method you don't

Possible Duplicate: Read a password from std::cin I'm trying to make a simple password program so I can get familiar with C++, but I'm having a bit of a problem. In this code, I ask the user for a password they choose, and then they enter it. What I want to code to do is hide the input ( not replace it with *s), but still show the cursor, and the text above, before, and after the password is entered, like this: Please enter password: [don't show input] Please re-enter password: [don't show input] How can I do this? I'm using Linux, so I won't be able to use any windows libraries (windows.h,

I want to get user input for multiple times and store the input data together in a string until input "quit" to quit from input. I think a for loop can work but I don't know how to do it. while True: user_input = raw_input("Enter something:") if user_input == "quit": break Try this: input_string = '' while 1: input = raw_input('Add to string: ') if input == 'quit': break input_string += input while True: input = raw_input('Prompt') print input if (input == 'quit'): break; 来源： https://stackoverflow.com/questions/12608654/how-to-get-user-input-repeatly-until-i-want-to-quit

How can I enter an input without causing the code to stop executing? I have been searching for an answer during the last 20 minutes without result. cin >> string; pauses the code AFAIK. Would I need to use mulithreading, or is there a better way? (I don't even know if multithreading would work.) I've recently started learning c++, I am a beginner to say the least, so please explain thoroughly and include any library I might need, thank you. There are two algorithms for getting input without blocking (pausing). The first is polling, the second is by event (interrupt). Polling For Input Polling

Is there any way to hide user input when asked for in C? For example: char *str = malloc(sizeof(char *)); printf("Enter something: "); scanf("%s", str);getchar(); printf("\nYou entered: %s", str); // This program would show you what you were writing something as you wrote it. // Is there any way to stop that? Another thing, is how can you only allow certain characters? For example: char c; printf("Yes or No? (y/n): "); scanf("%c", &c);getchar(); printf("\nYou entered: %c", c); // No matter what the user inputs, it will show up, can you restrict that only // showing up if y or n are entered?
