C++ 04: cin Functions
1) cin.ignore() : The cin.ignore() function is used which is used to ignore or clear one or more characters from the input buffer. 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.
