Identify the syntax for an 'if' statement

• if expression

• if { expression }

• if (expression)

• if {expression]

Select the control structure that will execute the loop bogy at least once although the condition is not fulfilled.

• for

• if ... else

• do ... while

• while

identify the CORRECT statement to write the condition statement in C++ based on the statement in Figure below.

• if (sum <=70) || (average = 25)

• if (sum <=70) || (average == 25)

• if (sum <=70) &&(average = 25)

• if (sum <=70) &&(average == 25)

Identify which is NOT a type of selection control structure.

• if

• nested if

• do ... while

• switch case

Identify a CORRECT type of looping control structure.

• for

• if ... else

• switch case

• break

Identify a statement that must be used in switch case control structure.

• continue;

• break;

• exit;

• return 0;

In while loop the loop counter must be initialized ____________.

• Within the loop

• Before entering the loop

• at the end of the loop

• None of the given answer

____________ statement is used inside a loop to skip the execution of statements inside the current iteration and jump to the beginning of the loop for next iteration.

• break

• continue

• exit

• for

Determine the number of repetitions that will occur for the looping control structure in Figure below.

• 10

• 13

• 14

• 15

Determine the output based on code Figure below
