The most important thing about if statements is that it takes in a boolean value in it. The general format of an if statement is as follows
if(somethingIsTrue()){
then do the following.
}
else{
}
Now an important part of a boolean is that in C++ a true value is anything that is not zero. So if you do
if(1){
then do something
}
else{
quit
}
Then it would proceed to do something. This is very useful for when you return a null value(ZERO!) or an actual value(Say 10000, or something like the word cow). This allows us to use it a little bit more dynamically.
Another thing is the formatting. There are a few different formats for doing an if statement. The generally accepted ways you should format are as follows;
if(somethingIsTrue)
{
then do something
}
OR
if(somethingIsTrue){
then do something
}
To sum it up.
An if statement allows us to control whether we do something or not. Which is a lot of trouble.
if(somethingIsTrue()){
then do whats in the brackets.
}
