The statements which are used for decision making<\/a> , are called conditional statements. <\/strong><\/p>\n\n\n\n

There are three conditional statements.<\/p>\n\n\n\n

\n
  1. conditional operator \/ Ternary operator<\/a><\/li>
  2. if statement<\/li>
  3. switch statement<\/a><\/li><\/ol>\n<\/div><\/div>\n\n\n\n

    Note:<\/p>\n\n\n\n

    Statement<\/strong>: –<\/p>\n\n\n\n

    \n

    A statement is an instruction given to the computer to perform some specific task or action . A statement can be either single or compound.<\/p>\n\n\n\n

    single statement specifies single task or action and it is always terminated by semicolon(;) .<\/p>\n\n\n\n

    A compound statement specifies multiple actions and is enclosed with curly brackets( { } ). it is also known as block.<\/p>\n\n\n\n

    By default the statements are executed init the same order in which they appear in the program and each statement is executed only once . serial execution of statements makes a program inflexible and unsuitable for most of the practical application.<\/p>\n\n\n\n

    To make a program more flexible control statement are used.<\/p>\n<\/div><\/div>\n\n\n\n

    control statements are classified into three categories.<\/strong><\/p>\n\n\n\n

    \n

    Conditional statements<\/strong><\/p>\n\n\n\n

    1. conditional operator or Ternary operator<\/li>
    2. if statement <\/li>
    3. switch statement<\/li><\/ol>\n<\/div><\/div>\n\n\n\n
      \n

      Iterative statements<\/strong> or Looping<\/p>\n\n\n\n

      1. for loop<\/li>
      2. while loop<\/li>
      3. do-while loop<\/li><\/ol>\n<\/div><\/div>\n\n\n\n
        \n

        Jump statements<\/strong><\/p>\n\n\n\n

        1. break statement<\/li>
        2. continue statement<\/li>
        3. goto statement<\/li><\/ol>\n<\/div><\/div>\n\n\n\n

          <\/p>\n\n\n\n

          Conditional or Ternary operator<\/strong>:-<\/p>\n\n\n\n

          It is a conditional statement and used for making decision when we have two options.<\/strong><\/p>\n\n\n\n

          It requires three operands so , also known as ternary operator.<\/p>\n\n\n\n

          syntax<\/p>\n\n\n\n

          condition ? <true block> : <false block> ;<\/strong><\/p>\n\n\n\n

          Comma(,)<\/strong><\/p>\n\n\n\n

          This operator is used for variable separator.<\/strong><\/p>\n\n\n\n
