Chapter 05 Worksheet

Name the three types of loops in C.

• loop, iterate, cycle

• foreach, until, repeat-until

• for, while, do-while

• for-each, loop-while, do-until

What will happen if the condition of a while loop is never false?

• The program will enter an infinite loop.

• The program will skip the loop entirely.

• The loop will run a fixed number of times.

• The program will terminate immediately.

How can you create a loop that counts down from 10 to 1 in C?

• for(int i = 10; i > 0; i--) { printf("%d\n", i); }

• while(i < 10) { printf("%d\n", i--); }

• do { printf("%d\n", i--); } while(i > 0);

• for(int i = 1; i < 11; i++) { printf("%d\n", i); }

What is the effect of using the continue statement in a loop?

• It terminates the loop immediately.

• It skips the current iteration and continues with the next iteration of the loop.

• It restarts the loop from the beginning.

• It exits the program entirely.

How can you create an infinite loop in C?

• for(;;) { /* code */ }

• while(1) { /* code */ }

• do { /* code */ } while(1);

• All of the above.

What is the purpose of the break statement in a loop?

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

• To terminate the loop immediately.

• To restart the loop from the beginning.

• To exit the program entirely.

How do you create a loop that iterates through an array in C?

• for(int i = 0; i < array_length; i++) { /* code */ }

• while(i < array_length) { /* code */ }

• do { /* code */ } while(i < array_length);

• All of the above.

What is the result of using a decrement operator in a for loop?

• It increases the loop counter.

• It decreases the loop counter.

• It has no effect on the loop counter.

• It causes the loop to terminate immediately.

How can you implement a loop that processes each element of a 2D array in C?

• for(int i = 0; i < rows; i++) { for(int j = 0; j < columns; j++) { /* code */ } }

• while(i < rows) { while(j < columns) { /* code */ } }

• do { /* code */ } while(i < rows && j < columns);

• All of the above.

What will happen if you use a break statement inside a nested loop?

• It will exit only the innermost loop.

• It will exit all loops immediately.

• It will skip to the next iteration of the outer loop.

• It will cause a compilation error.
