Code within the braces forms a new scope and should be indented.
// tell the user if a is equal to
ten
if($a==10)
{
printf("a is ten.\n");
}
else
{
printf("a is not ten.\n");
}
Naming
The names of variables, constants, and functions are to begin with a lowercase letter. In
names that consist of more than one word, the words are written together and each word
starts with an uppercase letter. Use short names for variables used in a small scope, such
as just inside a for loop. Use longer names for variables used in larger scopes.
Function names should begin with a lowercase letter and use capitals for subsequent
words.
