Execution speed of overloaded functions

Hi,
Does function overloading affect the speed of execution of the program
?
If so what is the reason ?
How does it compare with a speed of a program using non-overloded
functions ?

No. Why should it? Overloaded or not, the function will be translated to an
address, or inlined, or whatever. Any cost in resolving which function to
call is at compile time, not run-time.
If so what is the reason ?
N/A

functions ?


The same.

No. Execution speed is not affected at all.
What may be affected is the speed of compilation.

If you provided over 3 trillion different functions all called foobar(), the
compiler might takes some time working out which version is a best match for
arguments provided.

For instance if you want to have generic print function for various structures, my implementation would be with a case statement: void print_structs(void * struct_argument, enum struct_type stype) { switch(stype) { case STRUCT_TYPE_1:

If a function should work with different types you normally overload it: void myfun(int a){ // do int stuff } void myfun(std::string str){ // do string stuff }

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
