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.
