CS201 Assignment #3 Solution

[+ "Boss" +]

Dear Student Please discus here about this Assignment :) . Thanks

[princes]

jo program is tarha kary return 0; say pahly   system("pause"); laga do  

[+ Fiiinder++]

 system("pause"); lagane se error de raha hai ka

system is not defined in this scope

[1q9u1izjoxrze]

errors aa rahian hain es main. Kiya code sy phele koi directory lagani hai??

[+ Fiiinder++]

koe btaye ga output rukti ku ni jaldi se chali jati hai????

[2j6qom3the51p]

@Fiinder system("pause"); add kro code k end pr output ruk jaye gi.

 CS201 Assignment 3(Solution)

• First of all create class with the name of computer with following code:

         class computer{

          }

• inside the class define 2 sections as private and public with following code:

        public: // for the public variables.
        void setModel(string s);
        string getModel();

         void setRamMemory(int i);
         int getRamMemory();
        
         computer();// define constructor without parameters
         computer(string, int);// define constructor with parameters
       
          private: // for the private variables.

          string Model;
          int RamMemory;

• After this close the class and your code should look like this 

 

• Now start working on defined functions above" let us start with default values for the constructor without parameters..

computer::computer(){
Model="None";
RamMemory=0;
}

• Now define the constructor's objects with values with following way:

computer::computer(string Model,int RamMemory){
setModel(Model);
setRamMemory(RamMemory);
}

• After doing this start writing SETTER function's code with following way:

void computer::setModel(string s){
 Model=s;
}
void computer::setRamMemory(int i){
 RamMemory=i;
}

• Same like this now write the code for GETTER functions defined above with following code:

string computer::getModel(){
return Model;
}
string computer::getRamMemory(){
return RamMemory;
}

• Now come to the final point with displaying values in program with the following way:

int main()
 {
 
  cout "computer without paramerters" endl;
       //initialize the constructor and display
  computer comp1; cout"Model == " comp1.getModel() endl;

cout"RAM Memory == " comp1.getRamMemory() endl;
cout "computer with paramerters" endl;
computer comp2("IBM",5);
cout"Model == "comp2.getModel() endl;
cout"RAM Memory == " comp2.getRamMemory() endl;

  return 0;
 }
