Question

Identify the false statement.

a. An inner nested loop must be entirely contained within its outer loop.
b. The body of the following loop executes 20 times: for(int x = 0; x < 4; ++x) for(int y = 0; y < 5; ++y) System.out.println("Hi");
c. You can place a while loop within a while loop or a for loop within a for loop, but you cannot mix loop types.

Answer 1

The false statement is c, which claims that you cannot mix loop types within each other in programming. In fact, you can nest different types of loops within each other, such as placing a for loop inside a while loop.

Step-by-step explanation:

Identifying the false statement among the options provided involves understanding nested loops and the flexibility of loop types in programming.

• Statement a: An inner nested loop must be entirely contained within its outer loop. This statement is true. The inner loop continues to run for each iteration of the outer loop until its condition is no longer met.
• Statement b: The body of the following loop executes 20 times: for(int x = 0; x < 4; ++x) for(int y = 0; y < 5; ++y) System.out.println("Hi"); This statement is also true. The outer loop runs 4 times, and for each iteration of the outer loop, the inner loop runs 5 times, resulting in 20 total executions of the print statement.
• Statement c: You can place a while loop within a while loop or a for loop within a for loop, but you cannot mix loop types. This statement is false. In programming, it's possible to mix different types of loops; for example, you can nest a for loop inside a while loop or vice versa. The corrected statement would be: You can nest different types of loops within each other, including mixing while loops with for loops.
