Question
Part 3 - Modify the following Program. Convert the following program as per comments
// program colors
// -> Convert class into .h header file and .ccp implemenation file and a main file.
// Keep int main() funciton same...
#include <iostream>
using namespace std;
#include <string>
/* srand example */
#include <ctime>
#include <stdio.h> /* NULL */
#include <stdlib.h> /* srand, rand */
class colorPicker {
private:
string colorArray[7];
public:
colorPicker() {
// Defalut Consructor assign values to array
// Use 7 assignment statements to assign each color to the color array
colorArray[0] ="Red";
colorArray[1] ="Green";
colorArray[2] ="Purple";
colorArray[3] ="Yellow";
colorArray[4] ="Orange";
colorArray[5] ="Indigo";
colorArray[6] ="Pink";
}
void printAllColors() {
// use for loop to print out all colors
for (int i = 0 ;i < 7; i++)
{ cout << colorArray[i] << endl;}
}
string randomColor() {
srand((unsigned)time(0));
// pick a random number between 1 and 7
int i =0;
i = rand()%7;
return colorArray[i];
}
};
int main()
{
colorPicker P;
//
P.printAllColors();
cout << "Random Color: " << P.randomColor();
system("pause");
return 0;
}
Explanation / Answer
Here is the code you wanted. Splitted the program into three files – color.h, color.cpp and main.cpp, where color.h contains the header file definition, color.cpp contain implementations and main.cpp has the main method to test the program. Drop a comment if you have doubts. Thanks.
//color.h
#ifndef color_h //defining header file
#define color_h
#include <iostream>
using namespace std;
#include <string>
#include <ctime>
#include <stdlib.h> /* srand, rand */
class colorPicker {
private:
string colorArray[7];
public:
//defining all the method prototypes
colorPicker();
void printAllColors();
string randomColor();
};
#endif //end of header file definition
//color.cpp
#include "color.h"
//implementation of all methods in header file
colorPicker::colorPicker() {
// Defalut Consructor assign values to array
// Use 7 assignment statements to assign each color to the color array
colorArray[0] ="Red";
colorArray[1] ="Green";
colorArray[2] ="Purple";
colorArray[3] ="Yellow";
colorArray[4] ="Orange";
colorArray[5] ="Indigo";
colorArray[6] ="Pink";
}
void colorPicker::printAllColors() {
// use for loop to print out all colors
for (int i = 0 ;i < 7; i++)
{ cout << colorArray[i] << endl;}
}
string colorPicker::randomColor() {
srand((unsigned)time(0));
// pick a random number between 1 and 7
int i =0;
i = rand()%7;
return colorArray[i];
}
//main.cpp
#include "color.h"
int main(){
//demonstrating the colorpicker class methods
colorPicker P;
P.printAllColors();
cout << "Random Color: " << P.randomColor()<<endl;
system("pause");
return 0;
}
//output
Red
Green
Purple
Yellow
Orange
Indigo
Pink
Random Color: Red
