for<\/strong><\/span> is a ‘C’ reserved keyword. <\/span><\/p>\n

Once you write the for loop you have to create parenthesis, and inside the parenthesis, you write three expressions.<\/span><\/p>\n

All three expressions are not compulsory, but you can write 3 expressions and those expressions are separated by semicolons. Two semicolons create three blocks for you inside the parenthesis. So, these two semicolons are compulsory, but whether to leave that block empty or filled, that depends upon your logic. <\/span><\/p>\n

    \n
  1. A for statement has 3 blocks created by 2 semicolons.<\/span><\/li>\n
  2. Writing 2 semicolons are mandatory.<\/span><\/li>\n
  3. But, you can leave any block empty.<\/span><\/li>\n
  4. Even you can leave all blocks empty, which creates an infinite loop. <\/span><\/li>\n<\/ol>\n

    { }<\/span><\/strong> this is a body of the for loop where you write your statements. <\/span><\/p>\n
