Break statement behavior in C Sharp (C#) - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to exit the loop when the number is 5.

C Sharp (C#)

for (int i = 0; i < 10; i++) {
    if (i == [1]) {
        break;
    }
    Console.WriteLine(i);
}

Drag options to blanks, or click blank then click option'

B5

C0

D1

💡 Hint

Common Mistakes

Using a number other than 5 in the condition.

Forgetting to use the break statement.

The break statement stops the loop when i equals 5.

2fill in blank

medium

Complete the code to break out of the while loop when count reaches 3.

C Sharp (C#)

int count = 0;
while (true) {
    Console.WriteLine(count);
    count++;
    if (count == [1]) {
        break;
    }
}

D10

💡 Hint

Common Mistakes

Using a wrong number in the condition.

Not incrementing the count variable.

The loop stops when count equals 3 due to the break statement.

3fill in blank

hard

Fix the error in the code to break the loop when the character 'q' is found.

C Sharp (C#)

char[] letters = { 'a', 'b', 'c', 'q', 'd' };
foreach (char letter in letters) {
    if (letter == [1]) {
        break;
    }
    Console.WriteLine(letter);
}

A"q"

B"letter"

Cq

D'q'

💡 Hint

Common Mistakes

Using double quotes for a character.

Using a variable name instead of a character literal.

Characters in C# use single quotes. So 'q' is correct to compare a char.

4fill in blank

hard

Fill both blanks to create a loop that breaks when the sum exceeds 10.

C Sharp (C#)

int sum = 0;
for (int i = 1; i <= 5; i++) {
    sum += i;
    if (sum [1] [2]) {
        break;
    }
}
Console.WriteLine(sum);

💡 Hint

Common Mistakes

Using < instead of >.

Using 5 instead of 10.

The loop breaks when sum is greater than 10.

5fill in blank

hard

Fill all three blanks to create a loop that breaks when the user inputs 'exit'.

C Sharp (C#)

string input;
do {
    Console.WriteLine("Type something (or 'exit' to quit):");
    input = Console.ReadLine();
    if (input [1] [2]) {
        [3];
    }
} while (true);

💡 Hint

Common Mistakes

Using != instead of ==.

Forgetting to use break to exit the loop.

The loop breaks when input == "exit".
