Raw string literal in C++ program
In this article, we will be discussing the raw string literal in C++, its meaning, and examples.
There are escape characters in C++ like “\n” or “\t”. When we try to print the escape characters, it will not display on the output. To show the escape characters on the output screen we use a raw string literal by using R”(String with escape characters)”. After using R in the front of the string the escape character will be displayed on the output.
Example
Let’s understand this with the help of an example
#include <iostream>
using namespace std;
int main(){
string str = "tutorials\npoint\n" ;
// A Raw string
string str_R = R"(tutorials\npoint\n)";
cout <<"String is: "<<str << endl;
cout <<"Raw String is: "<<str_R;
return 0;
}Output
If we run the above code it will generate the following output −
String is: tutorials point Raw String is: tutorials\npoint\n
Example
#include <iostream>
using namespace std;
int main(){
string str = "tutorials\ttoint\t" ;
// A Raw string
string str_R = R"(tutorials\tpoint\t)";
cout <<"String is: "<<str << endl;
cout <<"Raw String is: "<<str_R;
return 0;
}Output
If we run the above code it will generate the following output −
String is: tutorials toint Raw String is: tutorials\tpoint\t
