Chapter 3

Suppose that name is a variable of type string. Write the input statement to read and store the input Brenda Clinton in name. (Assume that the input is from the standard input device.)

Write a C++ statement that uses the manipulator setfill to output a line containing 35 stars, as in the following line: ***********************************

Suppose that age is an int variable and name is a string variable. What are the values of age and name after the following input statements execute: cin >> age; getline(cin, name); if the input is: a. 23 Lance Grant b. 23 Lance Grant

Suppose that age is an int variable, ch is a char variable, and name is a string variable. What are the values of age and name after the following input statements execute: cin >> age; cin.get(ch); getline(cin, name); if the input is: a. 23 Lance Grant b. 23 Lance Grant

The following program is supposed to read two numbers from a file named input.dat and write the sum of the numbers to a file named output.dat. However, it fails to do so. Rewrite the program so that it accomplishes what it is intended to do. (Also, include statements to close the files.) #include #include using namespace std; int main() { int num1, num2; ifstream infile; outfile.open("output.dat"); infile >> num1 >> num2; outfile << "Sum = " << num1 + num2 << endl; return 0; }

What may cause an input stream to enter the fail state? What happens when an input stream enters the fail state?

Which header file needs to be included in a program that uses the data types ifstream and ofstream?

Suppose that infile is an ifstream variable and employee. dat is a file that contains employees' information. Write the \(C++\) statement that opens this file using the variable infile.

Suppose that infile is an ifstream variable and it is associated with the file that contains the following data: 27306 savings \(7503.35 .\) Write the \(\mathrm{C}++\) statement(s) that reads and stores the first input in the int variable acctNumber, the second input in the string variable accountType, and the third input in the double variable balance.
