strncmp功能: 比较字符串str1 和 str2中至多count个字符。返回值如下: 返回值 解释 less than 0 str1 is less than str2 equal to 0 str1 is equal to str2 greater than 0 str1 is greater than str2 如果参数中任一字符串长度小于count, 那么当比较到第一个空值结束符时,就结束处理 1 #include <s...
在C语言中，`int` 是一个基本的数据类型，它代表整数（Integer）。整数与int 在计算机编程中，整数是没有小数部分的数字。例如，10、-5和0都是整数。C语言中的 `int` 类型被用来存储这样的数值。`int` 类型的变量可以有一个正数或负数作为值，这取决于该变量的具体内容和程序是如何操作的。int的...

整数常量(integer constant)是表示整数值的十进制(以10为基数)、八进制(以8为基数)或十六进制(以16为基数)数。使用整数常量表示无法更改的整数值。 整数常量为正,除非它们前面有减号“-”。减号被解释为一元算术否定运算符。 如果整数常量以0x或0X开头,则为十六进制。如果它以数字0开头,则为八进制。否则,假定为...
