Which keyword is used to skip the rest of the code in the current iteration and jump to the next iteration in a loop?

skip

continue

pass

1 answered

In C programming, what does the 'break' statement do?

Ends the loop and transfers control to the statement immediately following the loop

Skips the current iteration and continues with the next iteration of the loop

Skips the loop entirely and resumes execution from the statement after the loop

Repeats the current iteration of the loop

1 answered

Which of the following looping constructs is more appropriate for situations where the number of iterations is unknown?

for loop

while loop

do-while loop

if-else statement

1 answered

What does the 'do-while' loop guarantee in C/C++ programming?

It guarantees that the loop will execute at least once, even if the condition is false initially

It guarantees that the loop will execute until the condition becomes false

It guarantees that the loop will never execute if the condition is false

It guarantees that the loop will execute a specific number of times

In Java, what is the difference between 'continue' and 'break' statements?

'continue' moves control to the next iteration of the loop, while 'break' terminates the loop and moves control to the statement after the loop

'continue' ends the loop and transfers control to the statement immediately following the loop, while 'break' skips the current iteration and continues with the next iteration of the loop

'continue' repeats the current iteration of the loop, while 'break' skips the loop entirely and resumes execution from the statement after the loop

'continue' ends the loop and transfers control to the statement immediately following the loop, while 'break' repeats the current iteration of the loop
