Chapter 7

Write \(\mathrm{C}++\) statements that do the following: a. Define an enum type, courseType, with the values ALGEBRA, BEGINNING SPANISH, ASTRONOMY, GBNBRAL CHBMISTRY, PHYSICS, and LOGIC. b. Declare a variable newClass of the type courseType. c. Assign ASTRONOMY to the variable newClass. d. Advance newClass to the next value in the list. e. Output the value of the variable newClass. f. Input value in the variable newClass.

Given: enum currencyType \\{DOLLAR, POUND, FRANK, LIRA, MARK); currencyType currency; which of the following statements are valid? a. currency = DOLIAR b. \(\quad\) cin \(>>\) currency c. currency \(=\operatorname{static}_{-}\) cast \(\langle\text {currencyType }>(\text { currency }+1)\) d. for (currency = DOLLAR; currency \(<=\) MARK; currencyt+) cout \(<<\) "*";

Define an enumeration type triangleType with values EQUILATERAL, RIGHT, ISOSCELES, and SCALENE. Also declare the variable triangle of type triangleType while defining this type.

include // int main() // { // int num = 5; // std::cout << "num = " << num << endl; // return 0; // } # What is wrong with the following program? #include // int main() // { // int num = 5; // std::cout << "num = " << num << endl; // return 0; // }

Consider the following C++ code: string str1; string str2; char ch; int index; cin >> str1; cin >> str2; cin >> index; ch = str1[index]; str1[index] = str2[index]; str2[index] = ch; cout << str1 << " " << str2 << endl; Answer the following questions: a. What is the output if the input is Hello There 2? b. What is the output if the input is Diamond Gold 0? c. What is the output if the input is C++ Java 1?

Suppose that you have the following statements: string str1, str2; cin >> str1 >> str2; if (str1 == str2) cout << str1 + '!' << endl; else if (str1 > str2) cout << str1 + " > " + str2 << endl; else cout << str1 + " < " + str2 << endl; Answer the following questions: a. What is the output if the input is Programming Project? b. What is the output if the input is Summer Trip? c. What is the output if the input is Winter Cold?
