strlen c code

Since it is the first article after the opening, Let's first look at a simple and practical function to enhance your confidence and then step by step to the complexity, it's easy to let it go. I still remember that when I was a beginner in C, I had

1. if it appears as a string, the compiler will automatically add a 0 to the string as the Terminator. For example, if you write "abc" in the Code, the compiler will help you store "abc \ 0 ".2. The direct string quantity is used as the initial

Strlen only works as a counter. It starts scanning from a memory location (which can start with a string, a location in the middle, or even an uncertain memory area, the counter value is returned until the first string Terminator '\ 0' is

# Include "stdio. H"# Include "string. H" Void main (){ Char AA [10];Printf ("% d", strlen (AA ));Printf ("% d", sizeof (AA ));} The result of running the program is strlen (AA) = 15. sizeof (AA) = 10. What is the problem? Strlen is the length of a

For character arrays and character pointers: 1. if it appears as a string, the compiler will automatically add a 0 to the string as the Terminator. For example, if you write "ABC" in the Code, the compiler will help you store "ABC \ 0 ". 2. The

sizeof () function 1, what is it?     sizeof is actually an operator, which is the same thing as those +,-, which is parsed when the program is compiled. Although we often see sizeof followed by parentheses, which are similar to functions, they

The strlen (char *) function is used to calculate the actual length of the string. The method is from the beginning to the First '\ 0'. If you only define that the initial value is not assigned to it, the result is not correct. It will be searched
