1、std::string比较 我们一般用str1.compare(str2) == 0来实现 2、const char* 的比较 我们一般用strcmp(p1, p2) == 0来实现 3、代码 4、结果 str1 == str4 str5 is null p1 == p3... 查看原文 xn*2图灵机实现 ;1” else: if(p==0):str4+=“0” else:p=0returnstr4def minglin(st...

另一个功能强大的比较函数是成员函数compare()。他支持多参数处理,支持用索引值和长度定位子串来进行比较。他返回一个整数来表示比较结果,返回值意义如下:0-相等〉0-大于 <0-小于。举例如下: string s(“abcd”); s.compare(“abcd”); //返回0

Fortunately, for C++ strings, all of the typical relational operators work as expected to compare either C++ strings or a C++ string and either a C string or a static string (i.e., "one in quotes"). For instance, the following code does exactly what you would expect, namely, it ...
strncmptakes the third argument of integer type to specify the number of characters to compare in both strings. The return values of the function are similar to the ones returned by thestrcmp. #include<stdio.h>#include<stdlib.h>#include<string.h>intmain(){constchar*str1="hello there 1";...
C语言代码很简洁,里面用到了不少的英文缩写。如果不了解这些缩写,程序的第一行都难以理解,更何况后续的学习。举个例子,部分初学者有可能把第一行的stdio写成studio,还不容易察觉。下面列出一些常见的英文缩写,便于初学者理解和记忆,做到事半功倍。 初学者可以在即刻编程的...
