Efficiency of code. goto and function call

I just started learning c++. [MinGw, c++14].

If I want to transfer the control of a program to certain part of the code such that the control doesn't flow to any other part of the code. which is more efficient ?

  1. Using switch with goto statement and dividing the program into fragments by using {..}
  2. Using switch with function call

pls. suggest if there's an other way more efficient than these 2 mentioned above!

Solution

  • I totally depend upon what you want to do. As you might know, everything that is achieved using goto can be done using the 3 flows sequences, selection and iteration it's not a good practice to use goto as it violates structured programming. As for purely choosing which would be more efficient in terms of performance goto might lead by a very insignificant margin.
