Which of the following is true for switch statement in C++?Select one:We need to put break statement at the end of the group of statements of a conditionWe can put a range for cases such as case 1..3None of the theseIt uses labels instead of blocks
Solution
The correct answer is: "We need to put break statement at the end of the group of statements of a condition"
Here's why:
-
In C++, the switch statement executes one block of code out of many. It's like an if-else-if ladder statement. The expression inside the switch statement decides which block of code should execute.
-
The break statement is used at the end of each group of statements in a case. If break is not present, the program will continue to execute the next case even if the expression does not match the case.
-
C++ does not support a range for cases such as case 1..3. Each case must be a constant or a literal.
-
It's true that switch statement uses labels (the case values) to determine which block of code to execute, but the options are not blocks, they are labels followed by specific code to execute. So, the statement "It uses labels instead of blocks" is not entirely accurate.
