int i = something;
if( i == 1)
   /* do something */;
else if( i == 2 )
   /* do something else */;
else if( i == 3 )
   /* do something completely different */;

You can use the way KaangaRoo has shown or if the decision depends only on the integer u will be interested using Switch-case Statement.
e.g.
Switch (integer)
{
case 1:{.
        .
         code
        .
       }
case 2:{.
        .
         code
       }
//like that
default:{
         code
        }
}

upon the values the integer takes the code will be executed.  If integer doesn't take any value u have accounted for, default code is executed

The switch command works well here too:

switch(i){
     case 1:
          (do something);
     break;

     case 2:
          (do something else);
     break;

     default:
          (default statement);
     break;
}

don't forget the confusing but fun ?: statements!

(the if expression)?(then exp):(else exp)

or the standard form

if(some expression)
{
  block of then expression
}
else if(some expression
{
  else if expression
}
else(optional)
{
  else expression
}

True, for a straight forward case like my example a swith is nicer, but 'if - else if' can be used with other comparisions then '=='

               int i = something;
               if( i < 5)
                  /* do something */;
               else if( 1 <= 10 || i > 17)
                  /* do something else */;
               else if( i == 13 )
                  /* do something completely different */;
               else
                  /* out of idea's ;) */;
