COCOMO model in Software Engineering - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the basic COCOMO effort estimation formula.

Software Engineering

effort = a * (KLOC [1] b)

💡 Hint

Common Mistakes

Using multiplication '*' instead of exponentiation '**'.

The COCOMO basic effort estimation formula uses exponentiation of KLOC by b, so '**' is the correct operator.

2fill in blank

medium

Complete the code to calculate development time (TDEV) in the COCOMO model.

Software Engineering

TDEV = c * (effort [1] d)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using multiplication '*' instead of exponentiation '**'.

Development time is calculated by raising effort to the power of d, so '**' is correct.

💡 Hint

Common Mistakes

Using '*' which multiplies instead of exponentiating.

The error is using '*' instead of '**' for exponentiation. The correct operator is '**'.

4fill in blank

hard

Fill both blanks to complete the COCOMO effort and time formulas.

Software Engineering

effort = a * (KLOC [1] b)
TDEV = c * (effort [2] d)

Drag options to blanks, or click blank then click option'

A**

B*

C+

D-

Attempts:

3 left

💡 Hint

Common Mistakes

Using multiplication '*' instead of exponentiation '**'.

Both formulas require exponentiation '**' for the power operations.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension for COCOMO effort multipliers.

Software Engineering

effort_multipliers = {factor: rating[1]1.0 for factor, rating in ratings.items() if rating [2] [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '+' instead of '*' for multiplication.

Using '<' instead of '>' in the condition.

The comprehension multiplies ratings, filtering those greater than 3.
