   The easiest way is to call strlen(). Seriously. It's already optimized by your compiler and/or library vendors, to be as fast as possible for your architecture. One common optimization is to remove the need to increase a counter, and compute the length from the pointer: size_t my_strlen(const char *s) {.

   The strlen function returns the length of the string, which is stored in the variable len. Finally, the program prints the length of the string using the printf function. Note that the strlen function does not count the null character ('\0') at the end of the string, so the length of the string will be one less than the size of the array that ...
