Unit #3-06

Learning Outcome

At the end of this lesson, you will be able to:

• understand and use a try catch statement

Review

• select statements

Lesson

• go over  Try Catch , Computer Based Problem Solving

Activity

• nil

Daily Assignment

• re-create the "Number Guessing Game" program from before, again

  • use an If ... Then ... Else, so the user is told if the number is correct or wrong

    • when they get the number wrong, ensure you tell them what the correct number was

  • use the random number generator to generate a new random number every time the program is started over

  • this time ENSURE that what the user is entering is actually an integer

    • if it is not an integer, then let the user know this and DO NOT let the program crash

• for your test cases, now you have 3 possible outcomes

  • from now on, 1 of your test cases MUST be if someone enters "invalid" data

• read  Try Catch , Computer Based Problem Solving

• more info about try ... catch for python

Extra

• recreate the same above program in C

  • remember C does not have a try ... catch or a good way to get strings or numbers nicely; so we will use the CS50 C library

// This program gets an integer, using the CS50 library

#include <stdio.h>
#include <cs50.h>

int main() {
    // this function gets an integer
    int someInt;

    // input
    someInt = get_int("Enter and Int: ");
    printf("Your last string was %d\n", someInt);

    printf("\nDone.\n");
    return 0;
