THE if-else STATEMENT

Introduction

When you want to take actions based on the outcome of the conditions, (true or false), then you can use the if-else statement.

Program/Example

The general format for an if-else statement is

if (condition) simple or compound statement   // s1 else simple or compound statement.  // s2 

If the condition is true then the s1 part is executed and if the condition is false then the s2 part is executed. For example,

if (a>b) printf (" big number is %d", a);   // s1 else printf (" big number is %d", b);   // s2 

if a is greater than (b) then s1 is executed. Otherwise s2 is executed.
