Free Pascal Lazarus Program Tutorial 5 - If Statements



If statements are used to make decisions.

The If Statement Expression Signs 
< Less Than
<= Less Than or Equal To
> Greater Than
>= Greater Than or Equal To
= Equal To
<> Not Equal To

The Syntax for the If Statement 
if then
begin
do something;
end;

If Statement Example 
if 5 > 2 then
begin
  writeln(‘5 Is Greater Than 2’);
end;

The Output 
5 Is Greater Than 2

Another If Statemet
if 5 < 2 then
begin
  writeln(‘5 Is Less Than 2’);
end;


There will not be any output because 5 is not less than 2.


If statements can have multiple conditions. This is referred to as if - else statements.

Syntax for the If - Else Statement

If <condition> then
begin
  do something;
end
else if <condition> then
begin
  do something;
end
else
begin
  do something;
end;
