Today we looked at the following problem<\/p>\n

Write a program which will allow a user to input<\/strong>\u00a0only a number in the range 0-100. An error message will be output<\/strong> if the number is invalid.<\/p>\n

The program will output a message when the number input is valid (after the loop for checking the number).<\/p>\n

We then worked through Analysis, Design, Implementation and Testing of the program.<\/p>\n

Analysis<\/h3>\n

Input – a number<\/p>\n

Process – check number is between 0 and 100<\/p>\n

Output – a message about the numbers validity<\/p>\n

Design<\/h3>\n

We looked at all three design methodologies and created designs in our jotter.<\/p>\n

Pseudocode<\/h4>\n
    \n
  1. Declare Integer Number<\/li>\n
  2. Get Number from user<\/li>\n
  3. While Number < 0 OR Number > 100<\/li>\n
  4. \u00a0 \u00a0 Display “Sorry that number is not valid”<\/li>\n
  5. \u00a0 \u00a0 Get number from user<\/li>\n
  6. End While<\/li>\n
  7. Display “That is a valid number”<\/li>\n<\/ol>\n

    Testing<\/h3>\n
    We tested the code with Normal, Extreme and Exceptional test data.<\/p>\n","protected":false},"excerpt":{"rendered":"
