String Literals: String literals are similar to that of the character literals, except that it can store multiple characters and uses a double quote to store the same. It can also accommodate the special characters and escape sequences mentioned in the table above.
Example:
```
// For C++
string stringVal = "GeeksforGeeks"
```
Example:
```
#include <iostream>
using namespace std;
  
int main()
{
    const string str = "Welcome\nTo\nGeeks\tFor\tGeeks";
    cout << str;
    return 0;
} 
```
Output:
```
Welcome
To
Geeks    For    Geeks
```
Boolean Literals: This literal is provided only in C++ and not in C. They are used to represent the boolean datatypes. These can carry two values:
- true: To represent True value. This must not be considered equal to int 1.
- false: To represent False value. This must not be considered equal to int 0.

Example:

#include <iostream>
using namespace std;
  
int main()
{
    const bool isTrue = true;
    const bool isFalse = false;
  
    cout << "isTrue? "
         << isTrue << "\n";
    cout << "isFalse? "
         << isFalse << "\n";
  
    return 0;
}

Output:

isTrue? 1
isFalse? 0
