now im on lesson 5

the tutorial doesnt seem to be helping that much. i dont really understand lesson 5.


any advice?





mabe i just need a break...

do you have any specific questions?

well ya, but you guys are going to get fed up with me if i ask all my questions about every lesson.

but heres one or a few.

it said that Switch case statements are a substitute for long if statements that compare to an integral value

how does this have anything to do with if statements? and"that compare to an integral value " makes no sence to me.

Code:

---

switch ( value ) {
case this:
  Code to execute if value == this
  break;
case that:
  Code to execute if value == that
  break;
...
default:
  Code to execute if value != this or that
  break;
}

---

then it said

"The condition of a switch statement is a value. The case says that if it has the value of whatever is after that case then do whatever follows the colon"

but in the example theres nothing for it to do....it just repeats itself..

in one of the sample programs i uses the word void yet it doesnt tell you what that word is!

now that i think about it, nothing in lesson 5 makes sence to me so.....
if your wondering what my question is read lesson 5
.

switch statements are simply a way to shorten your code. For example, rather than writing:

Code:

---

if (x==5)
  //do something
else if (x==6)
  //do something else
else if (x==7)
  //do something else
//etc

---

You can write this:

Code:

---

switch(x)
{
case 5:
  //do something
break;
case 6:
 //do something else
break;
case 7:
 //do something else
break;
}

---

Which will probably make the code easier to read and a bit shorter if you have a bunch of values to test against.
