[#52] What is the purpose of the 'continue' statement in a loop?
Correct Answer

(C) Skip the current iteration

Explanation

Solution: The purpose of the 'continue' statement in a loop is to skip the current iteration and proceed to the next iteration of the loop. When 'continue' is encountered within a loop, it immediately terminates the current iteration and continues with the next iteration, effectively skipping any remaining code within the current iteration's body. So, the correct answer is: Option C: Skip the current iteration

[#53] What is the range of values that can be stored in an 'int' data type in C?
Correct Answer

(B) -2147483648 to 2147483647

Explanation

Solution: The range of values that can be stored in an 'int' data type in C is Option B: -2147483648 to 2147483647 . An 'int' is typically represented as a 32-bit signed integer on most systems, which allows it to store values within this range. So, the correct answer is: Option B: -2147483648 to 2147483647
