You want to write a program that prints the name of a day based on an integer (1 to 7). Which is the best approach?
AUse a switch statement with cases 1 to 7 for each day
BUse multiple if statements checking ranges like 1<=x<=7
CUse a switch statement with floating-point cases
DUse if statements comparing strings
Step-by-Step Solution
Solution:

  1. Step 1: Identify the input and output

    Input is an integer 1 to 7, output is a day name for each number.

  2. Step 2: Choose the best control structure

    Switch is ideal for discrete integer values; floating-point cases are invalid; if with ranges is less clear; strings comparison is unrelated.

  3. Final Answer:

    Use a switch statement with cases 1 to 7 for each day -> Option A

  4. Quick Check:

    Best structure for discrete int = D [OK]
Quick Trick: Switch fits fixed integer options like days 1-7 [OK]
Common Mistakes:
  • Trying to use switch with floats
  • Using if with ranges unnecessarily
  • Comparing strings instead of integers
