Which of the following functions can be used to find the length of a string in C?a.length()b.strlength()c.strlen()d.size()

To determine which function can be used to find the length of a string in C, let's analyze each option:

1. a. length(): This function is not used in C for strings. It's commonly found in C++ for string objects led to by std::string.

2. b. strlength(): There is no standard function named strlength() in C.

3. c. strlen(): This is the correct function to find the length of a string in C. It is defined in the <string.h> header.

4. d. size(): Like length(), the size() function is typically associated with C++ STL containers and objects, not standard C strings.

Final Answer

The correct function to find the length of a string in C is c. strlen().
