typedef struct one_info; int main() --- from a performance point of view, is there anything that'd make me chose one of the options over the other? However most compilers are not naive and will inline and optimise small memcpy()s.

Unless the compiler is pervesely written the furxt should never be less efficient than the last.

This is useful when we are doing assignment of only few members of the structure.

In the following example the structure variable s2 has only one member assignment.

Before compiling and executing below C program, create a file named “structure.h” and declare the below structure.

struct student record; In this program, above created header file is included in “structure.c” source file as #include “Structure.h”.

As I explained above that once you declared a structure, the struct struct_name acts as a new data type so you can include it in another struct just like the data type of other data members. The simple solution to this issue is use of typedef. Code without typedef Instead of using the struct home_address every time you need to declare struct variable, you can simply use addr, the typedef that we have defined.

We have already learned two ways to set the values of a struct member, there is another way to do the same using designated initializers.

typedef struct one_info; int main() --- from a performance point of view, is there anything that'd make me chose one of the options over the other? typedef struct one_info; int main() --- from a performance point of view, is there anything that'd make me chose one of the options over the other? On the implementations I'm aware of, there is no noticeable difference in performance, because equivalent code is generated for both options. If you want to post a code sample, please try compiling it first, then copy-and-paste it exactly.

Your meaning happens to be clear enough in this case, but in general you'll save us a lot of time by posting real code.
