compare(1, 3, s2, 1, 3); // 比较 "ell" 和 "orl" if (result3 < 0) { std::cout << "The substring of s1 is less than that of s2" << std::endl; } else if (result3 == 0) { std::cout << "The substrings are equal" << std::endl;...
("Result: %d\n", result); // 输出 Result: 0 return 0; } ``` ### 比较字符串 对于字符串的比较,可以使用标准库中的`strcmp`函数,但为了展示如何自己实现类似功能,这里提供一个简单的例子: ```c #include <stdio.h> int compare_strings(const char *str1, const char *str2) { while (*str...
2. Comparing Strings: Comparing strings requires special attention due to their nature as arrays of characters in C. The standard library function 'strcmp()' can be used to compare two strings. It returns an integer value, with 0 indicating that the strings are identical, negative values implyi...

C++不区分大小写比较string类似CString.compareNoCase,使用transform();全转化为小写,然后对比stringstring与CString互相转换:stringstr;CStrings;s=str.c_str();str=s;
