Escape Sequences in C++
Escape Sequences in C++ are special character constants to represent non graphical characters in C++.
Most common non graphical characters include enter key, backspace, tab etc.
They start with a backward slash ( \ ) followed by a specific character.
Most commonly used escape sequences in C++ are:
1) \n

int main()
{
cout<<“Welcome”;
cout<<“\nBye “;
return 0;
}
Output:
Welcome Bye
2) \t
To leave a gap of 8 spaces.
#include<iostream>
using namespace std;
int main()
{
cout<<“Welcome \t Bye “;
return 0;
}
Output
Welcome Bye
3) \b
To delete a character appearing before it.
#include<iostream>
using namespace std;
int main()
{
cout<<“Welcome\b Bye “;
return 0;
}
Output:
Welcom Bye
4) \\

#include<iostream>
using namespace std;
int main()

cout<<“Welcome\\ Bye “;
return 0;
