Synopsis

               statement := if ( condition ) statement | 
    if ( condition ) statement else statement
               condition ::= expression | type-specifier-seq 
               declarator = assignment-expr
            

The if statement tests condition, and if it is true, executes the first statement. If condition is false, and an else part is present, the else statement is executed; if there is no else part, execution continues with the statement immediately after the end of the if statement. If condition contains a declaration, the declared name is in the scope of both the if and else statements.
