What is Echoing the Input?

[ZahoorKhan]

What is meant by echoing the input in C++?

[CodeBlob]

Output (print) the input as an example :

int x = 0;
cin >> x;
cout << x;

It is just English language not something related to c++

[ZahoorKhan]

#CodeBlob I don't understand clearly.

@Khan: where did you heard it, anyway?

[CodeBlob]

Echo a sound or series of sounds caused by the reflection of sound waves from a surface back to the listener.
the point here is echo is just a word not something related to c++, what is meant by this is to take input from the user and output it

https://en.wikipedia.org/wiki/Echo_(command)

echo is an old unix/DOS/shell command that simply types back whatever text you type in. like a print command. There is a C implementation example in the link above if you want to code it but it's not really very useful outside of shell scripts.
