A. Rewrite the following program using switch statement: int main() { int testScore; // Holds a numeric test score char grade; // Holds a letter grade cout << "Enter your test score and I will tell you\n"; cout << "the letter grade you earned: "; cin >> testScore; if (testScore = = 60) grade = 'F'; if (testScore = = 70) grade = 'D'; if (testScore = = 80) grade = 'C'; if (testScore = = 90) grade = 'B'; if (testScore = = 100) grade = 'A'; cout << "Your grade is " << grade << ".\n"; return 0; } B. Rewrite the following code, replacing the do-while loop with a while loop. When you do this you will no longer need an if statement. int number; cout << "Enter an even number: "; do { cin >> number; if (number % 2 != 0) cout << "Number must be even. Reenter number: "; } while (number % 2 != 0); C. Given an array definition as follows, write the codes which will determine the highest value. const int SIZE = 10; int numbers[SIZE] = {15, 6, 3, 11, 22, 4, 0, 1, 9, 12};
Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
A. Rewrite the following program using switch statement:
int main()
{
int testScore; // Holds a numeric test score
char grade; // Holds a letter grade
cout << "Enter your test score and I will tell you\n";
cout << "the letter grade you earned: ";
cin >> testScore;
if (testScore = = 60)
grade = 'F';
if (testScore = = 70)
grade = 'D';
if (testScore = = 80)
grade = 'C';
if (testScore = = 90)
grade = 'B';
if (testScore = = 100)
grade = 'A';
cout << "Your grade is " << grade << ".\n";
return 0;
}
B. Rewrite the following code, replacing the do-while loop with a while loop. When you do this you will no longer need an if statement.
int number;
cout << "Enter an even number: ";
do
{ cin >> number;
if (number % 2 != 0)
cout << "Number must be even. Reenter number: ";
} while (number % 2 != 0);
C. Given an array definition as follows, write the codes which will determine the highest value.
const int SIZE = 10;
int numbers[SIZE] = {15, 6, 3, 11, 22, 4, 0, 1, 9, 12};
D. Define the following arrays:
i. empNum, a 100-element array of ints
ii. payRate, a 25-element array of doubles
iii. miles, a 14-element array of floats
iv. letter, a 26-element array of chars
v. lightYears, a 1,000-element array of doubles
