How to ignore INPUT in C++
By pop1912, history, 4 years ago, In English

Hi, I'm using "cin.ignore()" to ignore the input. I want only the 2nd integer to be displayed for this sample Input, I'm getting WA for some Test Cases, What is wrong in my code?:

Testcase 1:(Output should be "1")

2 1
carrots?
bunnies

Testcase 2:(Output should be "5")

1 5

My Code:

#include<iostream>
using namespace std;

int main() {
    int a;
    cin.ignore();
    cin>>a;
    cin.ignore();
    
    cout<<a;
    
    return 0;
}

Just read input into a dummy variable and do not use it.

    Yup, that worked, but using "cin.ignore()" is not working... any Idea?

      Have you read doc on the istream::ignore()? It should not work in your case.
