P.S - Scan files before executing.

My advice get a branded pc instead of assembled one..

So, this is how those chinese vendors from ebay make the fake pen drives. Thanks for sharing!

you are rite...!! At my place we deal with such shit everyday .. my friend has a code that reads the actual disc space..

I made this program when i was kid(around 14Y.O)...at that time i was learning batch program.This is simple and easily understandable for those who are learning batch programing.Feel free to edit and re-post.It is not a virus,so dont worry.I have some tutorials at my youtube channel..  


Edit- Dont use option 3.It wont work but if u mess with it i am not responsible for your loss

You should use #include <cstdlib> in order to use "system" actions, like system("PAUSE");, or system("CLS");. It should work if you include that.


On a side note, you may want to create functions for finding the sum, difference, product, and quotient to make your main program source code more neat, and structured.


For example:

Code: [Select]


#include<iostream>


double findSum(double n1, double n2)
{
    double sum = n1 + n2;
    return (sum);
}


int main()
{
    double num1, num2;


    std::cout << "Input 1st number:";
    std::cin >> num1;
    std::cout << std::endl;
    std::cout << "Input 2nd number:";
    std::cin >> num2;
    std::cout << std::endl;


    // Output
    std::cout << num1 << " + " << num2 << " = " << findSum(num1, num2);


    std::cin.ignore();
    return 0;
}


I was not able to understand your code as i am in learning stage..i tried to compile and run your code but it seems like cin.get() isnt working..i dont know but why..anyways thanks for your help.

#include <iostream>
#include <cmath>




int main()
{
    using namespace std;
   
    double answer;
    double option;
    double num1;
    double num2;
   
    do{
   
    cout << "Enter operator <1=add 2=subtract 3=multiply 4=divide>" << endl;
    cin >> option;
   
    if (option == 1)
       {
       
        cout << "Enter first number" << endl;
        cin >> num1;
        cout << "Enter second number" << endl;
        cin >> num2;   
        cout << "answer is" << endl;
        cout << num1 + num2 << endl;
        cout << endl;
}   
    else if (option == 2)
    {
        cout << "Enter first number" << endl;
        cin >> num1;
        cout << "Enter second number" << endl;
        cin >> num2;   
        cout << "answer is" << endl;
        cout << num1 - num2 << endl;
        cout << endl;
}   
    else if (option == 3)
    {
        cout << "Enter first number" << endl;
        cin >> num1;
        cout << "Enter second number" << endl;
        cin >> num2;   
        cout << "answer is" << endl;
        cout << num1 * num2;
        cout << endl;
    }   
    else if (option == 4)
       { cout << "Enter first number" << endl;
        cin >> num1;
        cout << "Enter second number" << endl;
        cin >> num2;   
        cout << "answer is" << endl;
        cout << num1 / num2 << endl;
        cout << endl;
   }   
   
   
   else{
       cout << "Enter the real operator you dingbat." << endl;
       }
} while(.1);




 
    system("pause");
    }

This is a basic calculator.I am still learning C++.This is a program i made with help from some tutorial.The problem is when i enter a option and use it smoothly .After that i need to clear the screen,it keeps stacking after using operators.I am not sure if u understood my problem.I tried using system("CLS") but i failed.Help me.

Thank you.
