This article illustrates the implementation method of C + + not using variables to find the strlen function of string length. Share to everyone for your reference. The implementation methods are as follows: 1, strlen source code to achieve:

First, sizeofsizeof (...) Is the operator, the typedef in the header file is unsigned int, the values are computed at compile time, and the arguments can be arrays, pointers, types, objects, functions, and so on.Its function is to obtain the size of

First, the definition: sizeof is an operator (operator) in C/s + +, which simply functions by returning an object or a type's memory byte count. Its return value type is size_t and is defined in the header file stddef.h. In a 32-bit system: The
