In C, the bool type usually occupies 1 byte, but the specific number of bytes depends on the compiler and platform implementation, and may occupy 2 or 4 bytes in special cases.
The number of bytes of bool type in C
The bool type in C is used to represent Boolean values, that is True or false. Its size depends on the compiler and platform implementation.
The bool type occupies 1 byte
on most 32-bit and 64-bit systemsIn some special cases
Example
<code class="cpp">#include <iostream> int main() { // 创建一个 bool 变量 bool isTrue = true; // 输出其占用的字节数 std::cout << "字节数: " << sizeof(isTrue) << std::endl; return 0; }</code>
Output
<code>字节数: 1</code>
