Can a function have string return type?
Strings in C are arrays of char elements, so we can’t really return a string – we must return a pointer to the first element of the string. All forms are perfectly valid. Note the use of const , because from the function I’m returning a string literal, a string defined in double quotes, which is a constant.
How do you pass a string to a function in Python?

How do I return a string to a pointer?
2 Answers. s++; move the pointer till ‘\0’ . It should be brought back 1 unit to point to actual string by putting s– . Other wise the copied one will start with ‘\0’ that will make it empty string.
How do you pass a string to a function in C?
In C, if you need to amend a string in a called function, pass a pointer to the first char in the string as an argument to the function. If you have allocated storage for the string outside the function, which you cannot exceed within the function, it’s probably a good idea to pass in the size.
How do you pass an argument in Python?
The special syntax *args in function definitions in python is used to pass a variable number of arguments to a function. It is used to pass a non-key worded, variable-length argument list. The syntax is to use the symbol * to take in a variable number of arguments; by convention, it is often used with the word args.
