一、字符串或字符常量缺少结束符:unterminatedstringorcharacterconstant，检查所有字符串是否都用双引号括起来的，字符常量用单引号括起来。二、C语言是一门通用计算机编程语言，应用广泛。C语言的设计目标是提供一种能以简易的方式编译、处理低级存储器、产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言
The Empty constant holds the empty string value. It is initialized by the EE during startup. It is treated as intrinsic by the JIT as so the static constructor would never run. Leaving it uninitialized would confuse debuggers. We need to call the String constructor so that the compiler does...
NSLog(@"%@", replacedStr); 1. 2. 3. 4. 在上面的示例中,我们首先定义了一个包含空字符的字符串常量emptyChar,然后我们使用stringByReplacingOccurrencesOfString:withString:方法将字符串str中的空字符替换为空格。 另一个常见的使用空字符常量的场景是检查一个字符串是否只包含空字符。下面是一个示例,展示了...

The std::string class has a built-in method empty() to check if the given string is empty or not. This method is of type bool and returns true when the object does not contain characters. The empty() method does not take any argument and implements a constant time complexity function....
string str1 = "Int32"; string str2 = typeof(int).Name; Console.WriteLine(obj == str1); // true Console.WriteLine(str1 == str2); // true Console.WriteLine(obj == str2); // false !? Surely if A equals B, and B equals C, then A equals C; that's thetransitive propertyof...
