After an if<\/code> and after an else<\/code> there needs to be exactly one statement. The statement after if<\/code> will be executed if the condition is true<\/code>, the statement after else<\/code> will be executed if the condition is false.<\/p>\n

Now the important thing to understand is the following:<\/p>\n

    \n
  1. \n

    A single semicolon ;<\/code> is a statement. It’s an empty statement and putting it behind if<\/code> or behind else<\/code> fullfils the requirements of a statement.<\/p>\n<\/li>\n

  2. \n

    A block between curly brackets {}<\/code> is a statement. It groups multiple statements together, but it is one statement and thus also fulfills the requirements.<\/p>\n<\/li>\n<\/ol>\n

    Any other statement that comes after the first statement after if<\/code> or else<\/code> has nothing to do with the if<\/code> or else<\/code> and will be executed like any other code would.<\/p>\n

    So to break down your example:<\/p>\n

    if(x > 0)\n    y = y + 100;\nelse;\n    y = y + 200;\n<\/code><\/pre>\n
    is equivalent to:<\/p>\n
    if(x > 0)\n    y = y + 100;  \/\/ first statement after if\nelse\n    ;             \/\/ first statement after else\n\ny = y + 200;      \/\/ separate statement uneffected by if or else\n<\/code><\/pre>\n
    Removing the else<\/code> gives us this:<\/p>\n
    if(x > 0)\n    y = y + 100;  \/\/ first statement after if\n\ny = y + 200;      \/\/ separate statement uneffected by if\n<\/code><\/pre>\n
    and of course the statement y = y + 200;<\/code> will be executed, because it has nothing to do with the if<\/code> or the else<\/code>.<\/p>\n<\/p><\/div>\n
    <\/div>\n<\/div>\n
