Write a full class definition for a class named Accumulator, and containing the following members: A data member named sum of type integer. A constructor that accepts no parameters. The constructor initializes the data member sum to 0. A member function named getSum that accepts no parameters and returns an integer. getSum returns the value of sum. A member function named add that accepts an integer parameter and returns no value. add increases the value of sum by the value of the parameter.

This is the answer:

:

class Accumulator
{
private:
int sum;
public:
Accumulator(){sum=0;}
int getSum(){return sum;}
void add (int x) {sum+=x;}
};

411: You are given a file named phonedir that consists of many lines containing three strings: lastname firstname emailaddress. Write a utility program that reads commands (from stdin). Each command has one of two possible forms: lookup string add lastname firstname emailaddress In the case of the first command (lookup), the program looks for a line in the phonedir file where either the firstname or lastname matches the string given. If it finds such a line it prints out all three parts of the line, separated by spaces: lastname firstname emailaddress If it does not find a match in the file it prints out the string it was looking for, followed by a colon followed by a space followed by the message "not found": string: not found In the case of the second command (add), the program appends the three strings given to the file phonedir. Hints and suggestions: (1) Define and use two functions named lookup and add. When your program reads the string lookup, your lookup function is called; when the program reads the string add, your add function is called. When either of these two functions are called, they then read whatever else is necessary for their command (one string for lookup and three strings -- lastname, firstname, and emailaddress-- for add). And then these functions do... whatever it takes to carry out the command. (2) When doing a lookup or an add, open up the file phonedir ... carry out the operation .. and then close up the file. EXAMPLE: suppose the phonedir file looked like this: arnow david arnow@panix.com bush george president@whitehouse.gov gates bill bill@microsoft.com here then is a sample session with the program (program output is in bold): lookup david arnow david arnow@panix.com lookup joe joe: not found add theplumber joe joetheplumber@nowhere.com lookup arnow arnow david arnow@panix.com lookup joe theplumber joe joetheplumber@nowhere.com and the phonedir file would now be: arnow david arnow@panix.com bush george president@whitehouse.gov gates bill bill@microsoft.com theplumber joe joetheplumber@nowhere.com

Assume a class Window with accessor method getWidth that accepts no parameters and returns an integer. Assume further an array of 3 Window elements named winarr, has been declared and initialized. Write a sequence of statements that prints out the width of the widest window in the array.

This is the answer: : int max_width = winarr[0].getWidth(); if (winarr[0].getWidth()==winarr[1].getWidth() &&  winarr[1].getWidth()==winarr[2].getWidth()) cout<<"0"; if (max_width < winarr[1].getWidth()) cout<<winarr[1].getWidth(); if (max_width < winarr[2].getWidth()) cout<<winarr[2].getWidth(); if (max_width>winarr[1].getWidth() && max_width>winarr[2].getWidth()) cout<< winarr[0].getWidth();
