// The ignore function is predefined in iostream. Its // purpose is simply to ignore, one character at // a time, any input defined in its call statement // defined as ignorable by position or type.from the // input buffer. This means your program can ignore // white space one character at a time, or perhaps all // white space besides new line characters, just tabs, // or any other useful combination. Your program might // also ignore all numeric or nun numeric input, or // perhaps accept only input within predefined ranges. // Given an input buffer that looks like this: 25 67 48 19 13 579 10 38 // Your code might look like this: cin >> a; cin.ignore(100, '\n'); cin >> b; // This code reads the first input from each line of // input, discarding the remainder from each line of // buffer input. Another sequence might be: 25 67 48 19 // comments here 13 579 10 38 // comments here while(cin.ignore(100, '/')){ cin.ignore(100, '/'); while(cin.get(ch)) cout << ch; cout << endl; } // This code will output only the comments from the // input, displaying them on the monitor. Ignore() // is used to bypass delimiters and other content.
