Int id sizeof unsigned long 这个是不对的。
WebC语言中变量默认 为有符号的类型,如要将变量声明为无符号数,则需要使用unsigned关键字 (C语言中只有整数类型能够声明为unsigned无符号变量)。. #include. int main () {. int i; //默认i为有符号数. signed int j; //显示声明j为有符号数. unsigned char min_value = 0; // … WebFeb 28, 2024 · 一、sizeof的概念 sizeof是C语言的一种单目操作符,如C语言的其他操作符++、--等。它并不是函数。 sizeof操作符以字节形式给出了其操作数的存储大小。操作数可以是一个表达式或括在括号内的类型名。 操作数的存储大小由操作数的类型决定。

This can be 4, 8, 16, 32... bits, but usually the processor can handle it as fast as possible. Type "long" is for when you need more precision, even at the expense of slower code.
WebTypes & Description. 1. Basic Types. They are arithmetic types and are further classified into: (a) integer types and (b) floating-point types. 2. Enumerated types. They are again arithmetic types and they are used to define variables that can only assign certain discrete integer values throughout the program. 3.
