25.

The 3 expressions in for loop are separated by semicolon (;)

For example,

for(int i=1; i<=10; i++)

cout << i;

The loop here has three expressions -

1. initiialisation (i=1)
2. condition to break (i<=10)
3. increment (i++)

All the expressions are separated by a semicolon.

Ans. semicolon (;)

26.

If condition in a while loop is never changed to false => the control never comes out of the loop

=> The loop executes forever, meaning an infinite loop

Ans. the results is an infinite loop

27.

3 basic control structures in a C++ program are -

1. sequence - the default flow of the program where control moves to the code lines sequentially.
2. selective - some set of code needs to be executed conditionally. (if-else, switch statements)
3. repetitive - when a set of code lines are to be executed again and again, loops are used.

Ans. They are "sequence", selective and repetitive.

28.

The statement counter = 24, assigns 24 to the variable counter instead of checking for equality which can by done by using double equal to (==). Hence, there is error in the logic of code which does not produce a compiler error.

Ans. Logical error
