The else if ladder:

There is another way of putting if’s together when multipath decisions are involved. A multipath decision is a chain of if’s in which the statement associated with each else is an if. General form:

The construct is known as else if ladder. The conditions are evaluated from the top (of the ladder), downwards. As soon as a true condition is found, the statement associated with it executed and the control is transferred to the statement – x (skipping the rest of ladder). When all the n conditions become false, then the final else containing the default will be executed. Figure show the logic of else if ladder.

For Example:

Let us consider an example of grading the students in an academic institution. Grading is done according to following rule:

Average Marks                                                                                  Marks

80 to 100                                                                                             Honors

60 to 79                                                                                              First Divisions

50 to 59                                                                                               Second Divisions

40 to 49                                                                                               Third Divisions

0 to 39                                                                                                 Fail

Sol: This grading is done using else if ladder as follows :

if ( marks >79 )

{

          grade= “honors”;

}

else if ( marks >59 )

{

          grade= “First Division”;

}

else if ( marks > 49 )

{

          grade= “ Second Division”;

}

else if ( marks > 39 )

{

          grade= “Third Division”;

}

else

          grade= “Fail”;
