Will you pass the skill check?

★☆☆

In a role playing game a player must perform a skill check if they want to succeed in an action they are attempting. Skill checks are performed with a twenty sided dice. The player has a skill (e.g. dexterity) and a modifier (to reflect any advantages or disadvantages in the situation). The skill and modifier are both integers. The skill, plus the dice roll, plus the modifier (which could be a negative number) must be more than a value decided by a "dungeon master" (the DM value) to succeed.

Make

Write a program to output the result of a skill check. The user enters the skill value, the modifiers value and the number needed to pass. A roll of 1 is always a fail and a roll of 20 is always a success before skill and modifiers are taken into account. If the skill value, plus the modifiers is greater than equal to the number required to pass, the skill check is passed.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the subprogram called check_skill that:

1. Returns one of five possible outcomes:
2. Automatic pass: if skill plus modifiers is greater than or equal to the DM value plus 5. No dice is rolled.
3. Critical fail: if the roll is a 1.
4. Critical success: if the roll is a 20.
5. Check passed: if the skill plus roll plus the modifier is greater or equal to the DM value.
6. Check failed: if the ability plus roll plus the modifier is less than the DM value.

Complete the main program so that:

1. The user can input the skill value as a positive integer.
2. The user can input the modifier value as a positive or negative integer.
3. The user can input the DM value.
4. The outcome of the skill check is output.

Typical inputs and outputs from the program would be:

Enter the skill value: 15
Enter any modifiers: 2
Enter the number to pass: 12
Automatic pass

Enter the skill value: 6
Enter any modifiers: -1
Enter the number to pass: 14
You rolled a 20
Critical success

Enter the skill value: 10
Enter any modifiers: 2
Enter the number to pass: 20
You rolled a 13
Check passed

Enter the skill value: 9
Enter any modifiers: -2
Enter the number to pass: 13
You rolled a 3
Check failed
