SpletInteger (computer science) In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits). Splet12. apr. 2024 · 1、C和C++语言中基本的数据类型有:字符型(char),整形(short, int, long), 浮点型(float, double) 同时字符型和整形还可以继续分为带符号的和不带符 …

Splet因为字面常量“1”的类型是int,所以“x+1”的计算会根据整型提升规则,得到int类型的值32768。. 之后你若是拿32768直接跟零比大小,自然是比零大的。. 若是把它赋值给一个16位整型变量,它就会被截断成“-32768”,于是也就小于零了。. 题主只需将把“x+1”改成 ... SpletWe can use short for small integers (in the range −32,767 to 32,767 ). For example, // small integer short a = 12345; Here, a is a short integer variable. Note: short is equivalent to short int. long Type Modifier If we need to store a large integer (in the range -2147483647 to 2147483647 ), we can use the type specifier long. For example, Splet02. apr. 2024 · 根據用法, __wchar_t 的變數會指定寬字元類型或多位元組字元類型。 在字元或字串常數之前使用 L 前置詞可指定寬字元類型常數。. signed 和 unsigned 為修飾詞,可搭配任何整數類資料類型使用,但不包括 bool。請注意,char、signed char 和 unsigned char 是三個適用於像是多載和範本機制的不同類型。 poolofficestop
