A loop allows you to execute a statement or groups of statements multiple times based on certain condition. In this lesson, we would consider four types of loops. We would also examine a few loop control statements.<\/p>\n

  1. while Loop<\/a><\/li>\n
  2. for Loop<\/a><\/li>\n
  3. do..while Loop<\/a><\/li>\n
  4. Nested Loop<\/a><\/li>\n
  5. Loop Control Statements<\/a><\/li>\n<\/ol>\n

    1. while Loop<\/strong><\/h4>\n

    A while loop is used to execute a statement or group of statements repeatedly so long as a given condition remains true.<\/p>\n

    The syntax is:<\/p>\n

    while(condition) {\r\n   statement(s);\r\n}\r\n<\/pre>\n
    The flow diagram for the while loop is shown below:<\/p>\n
    \"While<\/a><\/p>\n
    The code below is an example of the while loop.<\/p>\n
    int<\/span> main<\/span> () {\r\n   int<\/span> x =<\/span> 0<\/span>;\r\n\r\n   \/\/ while loop<\/span>\r\n   while<\/span>( x <<\/span> 10<\/span> ) {\r\n\t   \/\/Statement<\/span>\r\n      cout <<<\/span> \"x =  \"<\/span> <<<\/span> x <<<\/span> endl;\r\n      x++<\/span>;\r\n   } \r\n   return<\/span> 0<\/span>;\r\n}\r\n<\/pre>\n
    If you run the above code,\u00a0 you’ll have the output:<\/p>\n
    x =  0\r\nx =  1\r\nx =  2\r\nx =  3\r\nx =  4\r\nx =  5\r\nx =  6\r\nx =  7\r\nx =  8\r\nx =  9\r\n<\/pre>\n
     <\/p>\n
    2. for Loop<\/strong><\/h4>\n
    In the case of a for loop, the\u00a0 statements are executed a specific number of times. So, the number times the loop with iterate is specified. The basic syntax of the for loop is:<\/p>\n
    for ( init; condition; increment ) {\r\n   statements;\r\n}\r\n<\/pre>\n
