foot tall telephone pole. During the day, it climbs 3 feet. However, while it sleeps at night, the bug s

lides back down 2 feet. How many days does it take the bug to reach its objective, the top of the pol

ave a program that displays the multiplication tables for her fourth graders. She wants the progr

am to accept any whole number (integer) from 1 to 9. The program then displays the multiplicat

ion tables from 1 to that number. A sample run might be as follows. Note she enters the underlin

ed number 4.

Enter a number from 1 to 9: 4 fd fd fd fd fd fd fd



1 x 1 = 1 x 1 = 1
1 x 2 = 2 x 1 = 2
1 x 3 = 3 x 1 = 3
1 x 4 = 4 x 1 = 4
2 x 2 = 2 x 2 = 4
2 x 3 = 3 x 2 = 6
2 x 4 = 4 x 2 = 8
3 x 3 = 3 x 3 = 9
3 x 4 = 4 x 3 = 12
4 x 4 = 4 x 4 = 16

re wishes a program that calculates the square footage of carpet a customer requires and determine

s his cost for installation based on the square footage. The program first asks him to enter the lengt

h and width of the room. It then displays the square-

footage. His installation cost is found by multiplying the square footage by 7.5%. A test run might

be:

Correct the errors in the following programs. If you are having trouble determining what is wro

ng, you can always make a test program, enter this coding and see what the compiler indicates
fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd



is wrong.

1. Why does this program not compile? Show what must be done to fix it?
fd fd fd fd fd fd fd fd fd fd fd fd fd



int main () { fd fd fd



cout << "Hi there!\n"; return fd fd fd fd fd



0;
}
#include<iostream> # d
f fd



include <iomanip> fd




solution: header includes must come first and needs the using namespace statement
fd fd fd fd fd fd fd fd fd fd fd



#include <iostream> # fd fd



include <iomanip> usi fd fd



ng namespace std; int fd fd fd fd



main () { fd fd



cout << "Hi there!\n"; return fd fd fd fd fd
