Problem 1 
---------
A.  Write a function which takes a character and a character string,
and returns the index of the last occurence of the character in the
character string.  The function should return a -1 if the character is
not in the string.

B.  Using the function from part A, write a program which reads in a
word from the terminal and prints out the letter immediately following
the final 'p' in the word.  If 'p' is the last letter in the word the
program should indicate that.  If 'p' is not in the word the program
should indicate that.

Example 1
----------
Give me a word: apple
The final p in apple is followed by l

Example 2
---------
Give me a word: orange
The word orange has no p

Example 3
---------
Give me a word: plop
p is the last letter in plop

Answer 1
--------

int last(char c, char s[])
{
    int i;
    int pos = -1;

    for (i=0; s[i] != '\0'; i++)
	if (s[i] == c)
	    pos = i;

    return pos;
}

void main()
{
    char s[20];
    int pos;

    cout << "Give me a word: ";
    cin >> s;

    pos = last('p',s);
    if (pos == -1)
        cout << "p is not in the word\n";
    else if (pos == strlen(s))
	cout << "p is the last letter\n";
    else
	cout << "The last p is followed by " << s[pos+1]" 
}


Problem 3 
---------
A.  Define a class called "employee" which has a first name, a 
last name, and a salary.

B.  Write a member function for employee, called "max_salary",
that takes an integer as input parameter.  The function should return 
the input integer if it is larger than the salary of the employee.  
Otherwise, the function should return the salary of the employee.

Answer 3
--------
class employee {
    private:
	char fname[20];
	char lname[20];
 	int salary;
    public:
	int max_salary(int x);
};

int employee::max_salary(int x)
{
    if (x > salary)
	return x;
    else
	return salary;
}



Problem 6
---------
A. What is the output of the following program?

#include <iostream.h>
#include <string.h>

void main()
{
    char word[10];
    strcpy(word,"success");
    int i;

    for (i = 0; word[i] != '\0'; i++)
        if (word[i] == 's')
            cout << "a";
        else
            cout << "b";
}

B. What is the output of the following program?

#include <iostream.h>
#include <string.h>

void main()
{
    char word[10];
    strcpy(word,"success");
    int i;

    for (i = 0; word[i] != '\0'; i++)
        if (word[i] == 's')
            cout << "a";

    cout << "b";
}
