Apr 13, 2020 Hello Friends this is simple code to change the text color or backgroung color in dev-C software. #include #include h #include h #include using namespace std; int main HANDLE a = GetStdHandle (STDOUTPUTHANDLE); SetConsoleTextAttribute(a. This brief guide discuss how to modify an object's color using C/C. The color used to display an object is specified in one of four ways ON::colorfromlayer - the object’s layer color, ONLayer::Color, determines the object’s color. This is the default method used when adding new objects to Rhino; ON::colorfromobject - the value of an object’s mcolor attribute.

C++ is an object-oriented programming language.
Change the color theme of the IDE. On the menu bar, choose Tools Options. In the options list, choose Environment General. In the Color theme list, choose either the default Blue theme, Dark, or Light. When you change a color theme, text in the IDE reverts to the default or previously customized fonts and sizes. C program for moving car graphics animation. In this program, we first draw a red color car on left side of the screen (x,y) and then erases it using cleardevice function. We again draw this car at(x + 5, y). This will look like a moving car from left to right direction. We will repeat above steps until car reaches the right side of screen. Personally, I don't understand a word of what you said, because I'm still not well developed in C language. Unlike your code, the system is easier to comprehend for beginniners. The Hello world is the first program you see in the tutorial, meaning that it's for beginners.
Everything in C++ is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.
Attributes and methods are basically variables and functions that belongs to the class. These are often referred to as 'class members'.
A class is a user-defined data type that we can use in our program, and it works as an object constructor, or a 'blueprint' for creating objects.

Create a Class
To create a class, use the
class
keyword:Example
Create a class called '
MyClass
': class MyClass { // The class
public: // Access specifier
int myNum; // Attribute (int variable)
string myString; // Attribute (string variable)
};
public: // Access specifier
int myNum; // Attribute (int variable)
string myString; // Attribute (string variable)
};
Example explained
- The
class
keyword is used to create a class calledMyClass
. - The
public
keyword is an access specifier, which specifies that members (attributes and methods) of the class are accessible from outside the class. You will learn more about access specifiers later. - Inside the class, there is an integer variable
myNum
and a string variablemyString
. When variables are declared within a class, they are called attributes. - At last, end the class definition with a semicolon
;
.
Create an Object
In C++, an object is created from a class. We have already created the class named
MyClass
, so now we can use this to create objects.Precision tune auto care winston salem nc. To create an object of
MyClass
, specify the class name, followed by the object name.To access the class attributes (
myNum
and myString
), use the dot syntax (.
) on the object:Example

Create an object called '
myObj
' and access the attributes:How To Change Color Of Moving Object Dev C 4
class MyClass { // The class
public: // Access specifier
int myNum; // Attribute (int variable)
string myString; // Attribute (string variable)
};
int main() {
MyClass myObj; // Create an object of MyClass
// Access attributes and set values
myObj.myNum = 15;
myObj.myString = 'Some text';
// Print attribute values
cout << myObj.myNum << 'n';
cout << myObj.myString;
return 0;
}
Run example »public: // Access specifier
int myNum; // Attribute (int variable)
string myString; // Attribute (string variable)
};
int main() {
MyClass myObj; // Create an object of MyClass
// Access attributes and set values
myObj.myNum = 15;
myObj.myString = 'Some text';
// Print attribute values
cout << myObj.myNum << 'n';
cout << myObj.myString;
return 0;
}
Multiple Objects
How To Change Color Of Moving Object Dev C Code
You can create multiple objects of one class:
Example
// Create a Car class with some attributes
class Car {
public:
string brand;
string model;
int year;
};
int main() {
// Create an object of Car
Car carObj1;
carObj1.brand = 'BMW';
carObj1.model = 'X5';
carObj1.year = 1999;
// Create another object of Car
Car carObj2;
carObj2.brand = 'Ford';
carObj2.model = 'Mustang';
carObj2.year = 1969;
// Print attribute values
cout << carObj1.brand << ' ' << carObj1.model << ' ' << carObj1.year << 'n';
cout << carObj2.brand << ' ' << carObj2.model << ' ' << carObj2.year << 'n';
return 0;
}
class Car {
public:
string brand;
string model;
int year;
};
int main() {
// Create an object of Car
Car carObj1;
carObj1.brand = 'BMW';
carObj1.model = 'X5';
carObj1.year = 1999;
// Create another object of Car
Car carObj2;
carObj2.brand = 'Ford';
carObj2.model = 'Mustang';
carObj2.year = 1969;
// Print attribute values
cout << carObj1.brand << ' ' << carObj1.model << ' ' << carObj1.year << 'n';
cout << carObj2.brand << ' ' << carObj2.model << ' ' << carObj2.year << 'n';
return 0;
}
