This article shows you what to pay attention to when C++ uses getline to get input from the command line. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Problem background

You may encounter it when doing the written test questions of C++, as follows:

An integer n and a string str are required from the command line.

The first line is required to enter an integer n, and the second line is used to enter a string.

Note: it can't be entered on the same line. The first line is an integer n and the second line is a string.

I seem to have repeated a question three times.

You may write the following code (didn't notice at first, that's what I wrote)

# include

# include

Using namespace std

Int main ()

{

Int N {}

String str

/ / enter N / /

Cin > > N

/ / enter a line of string / /

Getline (cin, str)

/ / print the input / /

Cout
