Property Painting Coding Question
TCS Coding Question Day 2 Slot 1 : Question 1
This question has been asked in the TCS NQT 2020 Day 2 Slot 1
Topic : Conditional Statement
Time Given : 15 Minutes
Difficulty : 2/5 stars
We want to estimate the cost of painting a property. Interior wall painting cost is Rs.18 per sq.ft. and exterior wall painting cost is Rs.12 per sq.ft.
Take input as
1. Number of Interior walls
2. Number of Exterior walls
3. Surface Area of each Interior 4. Wall in units of square feet
Surface Area of each Exterior Wall in units of square feet
If a user enters zero as the number of walls then skip Surface area values as User may don’t want to paint that wall.
Calculate and display the total cost of painting the property
Example 1:
