so I used a function strcasecmp() to do so. I found that this function is not C standard, so I wanted to know which errors can this function generate and if there is another way to compare the strings using strupr() function or some other function that's C standard. Thanks in advance...
我们使用std::string::compare()函数比较两个字符串对象。如果两个字符串相等,则返回“ 0”;如果比较的字符串较短,则返回整数<0;如果比较的字符串较长,则返回整数> 0。我们可以根据需要以各种形式使用std::string::compare()函数,下面讨论一些方法。 引用:std::string::compare() 范例1: 语法: string::compa...
";int result = strcmp(str1, str2); // Compare the two stringsif (result == ) {printf("The strings are equal.\n");} else {printf("The %s is not equal to %s\n", str1, str2);}return;} 输出结果如下：The strings are not equal 我们了解了如何复制字符串、获取字符串的长度，以及...
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...
strcoll:Compare two strings using locale //用语言环境来比较两个字符串 根据当前选择的C语言环境的LC_COLLATE类别来比较两字符串。在比较之前还可以设置语言环境,C标准库提供了这样的函数。 strxfrm:Transform string using locale //用语言环境转换字符串 ...
compare函数在>时返回1,<时返回-1,==时返回0 string的子串: string substr(int pos = 0,int n = npos) const;//返回pos开始的n个字符组成的字符串 string的交换: void swap(string &s2); //交换当前字符串与s2的值 string类的查找函数: int find(char c, int pos = 0) const;//从pos开始查找字...
6.1 C-strings(C 风格字符串) C风格字符串: 字符数组是元素为字符型的数组,字符串是以空字符'\0' 作为数组最后一个元素的字符数组。 如果指定了数组的大小,而字符串的长度又小于数组大小,那么这个数组其余的元素都将被初始化为'\0'。 为了在一个字符串中包含一个双引号,必须在这个双引号的前面加上一个反斜...

How do I Compare two Dates How do i compile this code in visual studio? How do I create a .lib (static library) file, by assembling a .asm file in Visual Studio 2010? How do I created a managed C++ DLL, that implements a C# interface? How do I debug .bat and .cmd files. How...
