_What does bool mean in c language?

_Bool represents Boolean type in C language. It is a simple data type containing only two values, true or false. It is used to represent the results of conditions or logical expressions. It usually occupies 1 byte of memory. And can only store true or false values.

_What does Bool mean in C language?

_Bool is the keyword representing Boolean type in C language. A boolean is a simple data type that contains only two values: true or false.

Usage:

_Bool is used to represent the result of a conditional or logical expression. For example:

<code class="c">int x = 10;
_Bool is_even = (x % 2 == 0);</code>

In this example, the is_even variable is a _Bool type variable whose value is determined based on whether x is an even number.

Size:

_The memory size occupied by variables of type Bool varies between compilers, but is usually 1 byte.

Scope:

_Bool type variables can only store true or false values.

Assignment:

_Bool type variables can be assigned values ​​through the assignment operator (=). For example:

<code class="c">_Bool is_true = true;
_Bool is_false = false;</code>

Usage:

_Bool type is mainly used in conditional expressions and logical operations. For example:

<code class="c">if (is_even) {
    // 执行代码段 A
} else {
    // 执行代码段 B
}</code>

In the above conditional expression, the Boolean value of is_even determines whether code segment A or code segment B is executed.

_Bool type can also be used with logical operators such as && (AND), || (OR), ! (NOT)).
