        case 3: printf("3 ");
        default: printf("None");
    }
}
int main() {
    solve();
    return 0;
}

What will be the output of the following code snippet?#include <std...
In the given code snippet, the switch statement is used to evaluate the value of the variable ch.
Since the value of ch is 2, it matches the case 2 label in the switch statement. The execution starts from case 2 and continues until the next break statement or the end of the switch block.
In this case, there is no break statement after each case, so the execution "falls through" to the next case. As a result, the statements for case 2, case 3, and default will all be executed.
Therefore, the output of the code will be: 2 3 None.
Note that if a break statement was added after each printf statement, the output would be different, and only "2" would be printed.
Hence, the correct answer is C. 2 3 None.

What will be the output of the following code snippet?#include <std...
Explanation:
Switch case in C allows multiple cases to be executed until a break statement is encountered. In this code snippet, the variable 'ch' has a value of 2.

Switch Statement:
- The switch statement checks the value of 'ch' and goes to the corresponding case.
- Since 'ch' is 2, it goes to case 2.

Output:
- The code will print "2 " because case 2 is matched.
- It will continue to execute the next cases as there are no break statements.
- Therefore, it will also print "3 " and "None".

Final Output:
The final output of the code snippet will be:
2 3 None
