Hey Scott,

I ran across this in another forum...maybe this is another approach you can take?

It is similar, I believe, to what you are trying to do.

While many say GOTO is bad I happen to believe its very handy. 20 is quite a lot though. A few goto's is ok - but 20 may be getting too much. Try replacing the with if/else.

Re: Completed Code but A LOT of GOTO...Replacement?

Hey, [edit] lol wow just realized this is over 5 year old thread

[/edit]

i was looking for an example of the goto command and came across this post.

firstly the way I interpret the switch is as a neat way to write a long chain of if else ifs. so..

c Syntax (Toggle Plain Text)
int i;
 
cin>>i;
 
//a chain of if else if
 
if(i==0){
   cout<<"i is 0\n";
}else if(i==1){
   cout<<"i is 1\n";
}else if(i==2){
   cout<<"i is 2\n";
else{
   cout<<"i is not 0 1 or 2\n";
}
 
//now as a case
 
switch(i){
 
case(0): cout<<"i is 0\n"; 
         break;
case(1): cout<<"i is 1\n";
         break;
case(2): cout<<"i is 1\n";
         break;
default: cout<<"i is not 0 1 or 2\n";
int i;

cin>>i;

//a chain of if else if

if(i==0){
   cout<<"i is 0\n";
}else if(i==1){
   cout<<"i is 1\n";
}else if(i==2){
   cout<<"i is 2\n";
else{
   cout<<"i is not 0 1 or 2\n";
}

//now as a case

switch(i){

case(0): cout<<"i is 0\n"; 
         break;
case(1): cout<<"i is 1\n";
         break;
case(2): cout<<"i is 1\n";
         break;
default: cout<<"i is not 0 1 or 2\n";

in your situation i would say functions are the way to go, and Dave is showing you something you want to strive towards, Abstraction, which is nice.

now functions work a little different and not only for math, math is easy way to show how a function works, but a function needs a couple things to set it up..

here is a great reference for C++ stuff
