a string can be created in a shorter way, for instance: char*p3=&"hello";printf("\n This is the content pointed by p3: %s ", p3); As we said, pointer also has its address. Now, let's make a pointer to pointer to char, we will use the pointer p that points to the char c...

C语言中的string及其深入解析 在C语言中，string这个词并不直接指代某种特定的数据类型，但它在编程领域中常被用作描述一系列字符组成的文本。在C的标准库中，我们通常使用字符数组（char array）或字符指针（char pointer）来表示和处理字符串。尽管C11标准引入了新的字符串处理函数，并且有其他库（如POSIX）也提供了...
