Programmers need to make sure that the data they allow into their programs is sensible. They can use input validation to check that the data is within a range.<\/p>\n

<\/p>\n

For example if we wanted a program that only allowed an age of between 0 and 120 years then we could use a IF statement to check.<\/p>\n

\"validation2\"<\/a><\/p>\n

However, this would only give the user two chances to get it right before the program continued anyway.<\/p>\n

By changing the if<\/strong> to a while,\u00a0<\/strong>the program will continue to ask the user for the age until it falls within the range.<\/p>\n

This is an example of input validation and is one of the standard algorithms you should know.<\/p>\n","protected":false},"excerpt":{"rendered":"
