When reading user input prefer not mix getline with operator as one reads and discards new line while the other does not and this can cause confusion as to where on the input stream you are. Secondly user input (when done manually) is usually line based (ie the input buffer is. User Input: Strings and Numbers C 12 Years Ago John A 1,896. User input/output is a key component in the programs you write, yet most online tutorials just provide a quick-and-dirty method of grabbing data. In other words, it works right up until the point the user does something unexpected.

The cin.ignore() function is used which is used to ignore or clear one or more characters from the input buffer. Mondo mod vst free download.

To get the idea about ignore() is working, we have to see one problem, and its solution is found using the ignore() function. The problem is like below.
Sometimes we need to clear the unwanted buffer, so when next input is taken, it stores into the desired container, but not in the buffer of previous variable. For example, after entering into the cin statement, we need to input a character array or string. So we need to clear the input buffer, otherwise it will occupy the buffer of previous variable. By pressing the “Enter” key after the first input, as the buffer of previous variable has space to hold new data, the program skips the following input of container.
Example
Output
There are two cin statements for integer and string, but only number is taken. When we press enter key, it skips the getLine() function without taking any input. Sometimes it can take input but inside the buffer of integer variable, so we cannot see the string as output.
Now to resolve this issue, we will use the cin.ignore() function. This function is used to ignore inputs upto given range. If we write the statement like this −

I am attempting to write a hangman game as a school project, and I am having trouble getting just one character from the input stream. This is the code I have so far:
Its pretty ugly, but it works ok. I don't yet know how to code something better (which is what I'm trying to find out). The original idea that I had was to read the text stream from the user into an array declared to size of 1, ignoring all other characters after the first character so as not crash the program.
There HAS to be a better way of doing this. I've read about the get function at cplusplus.com. cplusreference.com, and I've googled the net but I've come up with nada.
