Usually we can define a variable for a C++ struct, as in
struct foo { int bar; }; Can we also define functions for a struct? How would we use those functions?

You cannot have functions in structs in C; you can try to roughly simulate that by function pointers though.
No, you can't. Structs can only contain variables inside, storing function pointers inside the struct can give you the desired result.
Return struct from a functionThe function returns a structure of type struct student . The returned structure is displayed from the main() function. Notice that, the return type of getInformation() is also struct student .
Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)
Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.
struct foo { int bar; foo() : bar(3) {} //look, a constructor int getBar() { return bar; } }; foo f; int y = f.getBar(); // y is 3 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
