Control Structure, C#.NET

Question: Which of the following is used to create a conditional statement in C#?
A
if

B
for

C
while

D
switch

Note: The if statement is used to execute code based on a condition.

Question: What will the following code output?
int x = 10; if (x > 5) Console.WriteLine("Greater"); else Console.WriteLine("Smaller");
A
Greater

B
Smaller

C
10

D
Error

Note: The condition x > 5 is true, so "Greater" is printed.

Question: Which keyword is used to exit a loop prematurely in C#?
A
exit

B
stop

C
break

D
continue

Note: The break statement is used to terminate the loop immediately.

Question: What is the purpose of the continue statement in a loop?
A
To end the loop.

B
To skip the current iteration and continue with the next one.

C
To restart the loop.

D
To pause the loop.

Note: To skip the current iteration and continue with the next one. Analysis: The continue statement skips the remaining code in the current loop iteration and proceeds to the next iteration.

Question: What will the following code output?
for (int i = 0; i < 3; i++) { if (i == 1) continue; Console.WriteLine(i); }
A
0 1 2

B
0 2

C
1 2

D
0 1

Note: When i is 1, the continue statement skips the output for that iteration.

Question: Which of the following is a valid switch statement?
switch (x) { case 1: break; default: break; }
A
Yes

B
No, it's incomplete

C
No, break cannot be used in case

D
No, default must come first

Note: Not available
1. Report
Question: What will happen if no case matches in a switch statement?
A
It results in an error.

B
The program will crash.

C
The default case will execute if defined.

D
Nothing will happen.

Note: If no cases match, the default block is executed, if it exists.

Question: What will the following code print?int num = 2;
switch (num) {
    case 1:
        Console.WriteLine("One");
        break;
    case 2:
        Console.WriteLine("Two");
        goto case 1;
    case 3:
        Console.WriteLine("Three");
        break;
    default:
        Console.WriteLine("Default");
        break;
}
AOne

BTwo

COne and Three

DDefault

Note: The output is "Two" followed by "One" due to the goto case 1;, but "Three" is not printed because it would not execute after the goto.

Report

Question: What is the purpose of the if-else structure?
A
To loop through a set of values

B
To execute code based on multiple conditions.

C
To execute code conditionally based on true/false evaluations.

D
To declare variables.

Note: The if-else structure allows execution of different code blocks based on whether a condition is true or false.

Question: Which of the following correctly implements a while loop?
A
while (x < 5) { x++; }

B
while (x < 5) x++;

C
Both

D
None

Note: Both forms are correct; The curly braces are optional if there is only one statement.
