The for Loop Header Can Contain Multiple Variables of the Same

question 7

Multiple Choice

The for loop header can contain multiple variables of the same type and multiple update expressions, separated by commas:

for (int i = 0; j = 3; i <= 5; i++, j--)
Which loop below correctly implements the same loop using a single counter in the loop control?

• A) int i=0;
• for (int j=3 ; j<=5 ; j++ )
• {
• i++;
• }
• B) Int i=3;
• for (int j=0 ; j<=5 ; j++ )
• {
• i++;
• }
• C) int j=3;
• for (int i=0 ; i<=5 ; j--)
• {
• i++;
• }
• D) Int j=3;
• for (int i=0 ; i<=5 ; i++)
• {
• . . .
• j--;
• }

Definitions:

Variable Costs

Expenditures that fluctuate in direct relation to production or sales volumes, such as labor costs and materials used.

Fixed Costs

are expenses that do not change in total over a period of time, regardless of the level of production or sales volume, such as rent or salaries.

Break-even Point

The point where the amount produced or sold generates revenue that matches the overall costs, leading to neither profit nor loss.

Unit Contribution Margin

The amount each unit sold contributes to profit, calculated by subtracting the variable cost per unit from the selling price per unit.
