Go To
Allows us to jump unconditionally when require and its not recommended to use Go To heavily.
Switch..Case
Statement allows to execute the case block based on the value of the variable or passed in switch i.e allow to do the condition base programming.
Problem
In my application I reach stage where I have to execute code of the Case 1 of the Switch..Case and if the the some condition satisfy I have to execute the code of Case 3 of Switch..Case.
Example
Solution
First solution to this problem is copy the code of case 3 and put it in the if block of case 1
Example
Second solution is to create function and put the code in that and than execute the code.
Third solution is to make use of Go To in switch..case block.

Problem
In my application I reach stage where I have to execute code of the Case 1 of the Switch..Case and if the the some condition satisfy I have to execute the code of Case 3 of Switch..Case.
Example
Switch(myvariable) { case 1: //statements …........ if ( expression ) execute case 3: break; case 2: ….. break; case 3: …...... break; }
Solution
First solution to this problem is copy the code of case 3 and put it in the if block of case 1
Example
case 1: //statements …........ if ( expression ) //code of case 3 break;But the problem with above solution is it make code redundant.
Second solution is to create function and put the code in that and than execute the code.
case 1: //statements …........ if ( expression ) Case3Code(); break; function Case3Code() { …. }The problem with this solution is that I have to create one Extra function which is no needed.
Third solution is to make use of Go To in switch..case block.
switch(MyVariable) { case 1: //statements …........ if ( expression ) goto case 3: break; case 2: ….. break; case 3: …...... break; }so Go to in Switch..Case allow me to do the thing easy and the maintainable way.
