# 1.19 Literals

A literal is a fixed value written directly in the source code. C++ provides different types of literals to represent integers, floating-point values, characters, strings, and Boolean values.

This example demonstrates the declaration of variables using different literal types.

## Source Code

```
#include <iostream>

int main()
{
    int number = 100;
    double price = 99.95;
    char grade = 'A';
    const char message[] = "Hello";
    bool status = true;

    std::cout << "Integer: " << number << '\n';
    std::cout << "Floating Point: " << price << '\n';
    std::cout << "Character: " << grade << '\n';
    std::cout << "String: " << message << '\n';
    std::cout << "Boolean: " << status << '\n';

    return 0;
}
```

## Output

```
Integer: 100
Floating Point: 99.95
Character: A
String: Hello
Boolean: 1
```

## Explanation

- `100` is an integer literal of type `int`.
- `99.95` is a floating-point literal of type `double`.
- `'A'` is a character literal enclosed in single quotes.
- `"Hello"` is a string literal enclosed in double quotes.
- `true` is a Boolean literal representing the logical value true.
- Each variable is initialized using a literal of the corresponding type.
- `std::cout` displays the value stored in each variable.
- Boolean values are printed as `1` for `true` and `0` for `false` unless `std::boolalpha` is enabled.
- `return 0;` terminates the program successfully.
