#1
What is the primary purpose of using control structures in programming?
To organize and structure code
To perform arithmetic operations
To control the flow of execution
To display output on the screen
#2
Which loop in programming executes the code block a specified number of times?
for loop
while loop
do-while loop
if-else loop
#3
What does the term 'iteration' mean in the context of loops?
The process of defining a loop
The process of executing a loop repeatedly
The process of breaking out of a loop
The process of initializing loop variables
#4
In a 'while' loop, under what condition does the loop continue to execute?
While the condition evaluates to true
While the condition evaluates to false
While the loop counter is less than a specified value
While the loop counter is greater than a specified value
#5
What is the purpose of the 'for' loop in programming?
To execute a block of code repeatedly as long as a condition is true
To execute a block of code a specified number of times
To execute a block of code at least once
To execute a block of code based on different conditions
#6
Which of the following is NOT a valid loop control statement in programming?
#7
What does the 'break' statement do in a loop?
It continues to the next iteration of the loop
It exits the loop immediately
It skips the current iteration and continues with the next one
It terminates the program
#8
What is a nested loop?
A loop that only executes once
A loop that is defined within another loop
A loop that executes without any condition
A loop that prints numbers in reverse order
#9
What is the difference between 'while' and 'do-while' loops?
There is no difference, they are synonymous
'do-while' always executes at least once
'while' always executes at least once
'while' loops can't have conditions
#10
What is the purpose of the 'switch' statement in programming?
To execute loops
To create nested conditions
To perform different actions based on different conditions
To exit a loop
#11
What does the 'else' statement do in an 'if-else' construct?
It always executes the code block following it
It executes only if the condition of the 'if' statement is false
It is used to break out of the loop
It repeats the loop iteration
#12
What is the purpose of the 'goto' statement?
To transfer control to a specified label within the same function
To exit the loop immediately
To repeat the current iteration of the loop
To terminate the program
#13
What is the purpose of the 'continue' statement in a loop?
To skip the remaining code in the loop and exit
To repeat the current iteration of the loop
To terminate the loop
To break out of the loop entirely
#14
What is a 'control structure' in programming?
A statement that changes the control flow of a program
A structure used to define data types
A structure used for error handling
A structure used to store data
#15
What is the difference between 'break' and 'continue' statements in a loop?
'break' exits the loop entirely, while 'continue' skips the current iteration and continues with the next one
'break' skips the current iteration and continues with the next one, while 'continue' exits the loop entirely
'break' and 'continue' are interchangeable
'break' and 'continue' both terminate the program
#16
In switch statements, what is the purpose of the 'default' case?
To execute if none of the other cases match
To exit the loop immediately
To repeat the loop iteration
To skip the current iteration and continue with the next one
#17
What is an advantage of using a 'for' loop over a 'while' loop?
'for' loops are more efficient
'for' loops can handle infinite loops better
'for' loops can easily express looping over a range
'for' loops always execute at least once
