1. Write a single C++ statement that will:
Print the string “C++” using the variable: string s = “Introduction to C++”.
2. Change the letter ‘c’ to ‘C in the following string:
Reprint the string with “C” given the code and using the string: string greeting = “Introduction to c++”
3. Write the C++ statement or statements that will:
Print the answer for regular division of the real numbers a / b + c and print the answer for integer division of the same values for integer numbers d / e + f.
For example, given float a=13, b=3, c = 10, the statements would print :
Regular division result = 14.3333
Integer division result = 14
4. Write the C++ statement or statements that will generate a random number between 100 and 110:
5. Write a C++ statement or statements that will:
Print the first two digits and the last two digits of any 4 digit number stored in an integer variable n.
For example, given int n = 5623, print
56 23.
6. Write C++ statements that will align the following three lines as printed in two 20 character columns.
Name Years President
Abraham Lincoln 1860-1865
Thomas Jefferson 1801-1809
7. Write a C++ statement or statements that will Output if a string has a length greater than 10, equal to 10 or less than 10.
Examples :
string str1 = “Four Score and Seven Years Ago” would output “String Length > 10”
string str2 = “Good Day” would output “String Length < 10”
string str3 = 0123456789” would output “String Length = 10”
8. Create a truth table and determine the results for the following equation and values
Equation : bool b = ((a+4< 7) || ((b-a > 10) && !(c*a == 8)))
Values : a = 2; b = 8; c = 4
9. Write a program using Atom and submit via Blackboard.
a. Request an integer whole dollar amount from the console.
b. Using the least amount of bills ($50,$20,$10,$5,$1) necessary, calculate how many of each bill type you will need to get to that value.
Output Example 1 (input is bold and italicized)
Enter a whole dollar amount as n integer: 633
You will need:
12 $50 bill(s).
1 $20 bill(s).
1 $10 bill(s).
0 $5 bills(s).
3 $1 bill(s).
Output Example 2 (input is bold and italicized)
Enter a whole dollar amount as an integer: 364
You will need:
7 $50 bill(s).
0 $20 bill(s).
1 $1 bill(s).
0 $5 bills(s).
4 $1 bills(s).
