  4. i made a program not by your help but i felt like showing off so here it is

    #include <iostream>

    using namespace std;

    int main ()

    }

    return 0;

    }

    just search online c++ click on the gdb website and control v this (cotrol a then control c this to copy all of this quickly)

  6. I made this function with the help of your tutorials 🙂
    int x = 1;
    int y = 2;

    if (x > y) {
    cout << "pizza is greasy" << endl;
    }

    else if (y > x) {
    cout << "greasy is pizza" << endl;
    }

    return 0;

  26. I added all the operations to the calculator from the earlier lesson using this <3! It's a bad calculator in everyday terms, but I got it to work. I could get away without using the operations' variables, but whatever.

    #include <iostream>

    using namespace std;

    int main()
    {
    int a;
    int b;
    int x;
    int div;
    int sum;
    int diff;
    int prod;

    cout<<"Please enter a number. ";
    cin>>a;
    cout<<"Please enter another number. ";
    cin>>b;

    div=a/b;
    sum=a+b;
    diff=a-b;
    prod=a*b;

    cout<<"Please choose your operation n1. Division n2. Addition n3. Subtraction n4. Multiplication n";
    cin>>x;
    if(x==1){cout<<"The division equals to "<<div<< " and the remainder equals to "<<a%b;}
    if(x==2){cout<<"The addition equals to "<<sum;}
    if(x==3){cout<<"The difference equals to "<<diff;}
    if(x==4){cout<<"The product equals to "<<prod;}
    if(x>4){cout<<"Invalid option, the program will now close.";}
    if(x==0){cout<<"Invalid option, the program will now close.";}
    return 0;
    }

  28. Can someone tell me what I did wrong?

    #include <iostream>

    using namespace std;

    int main()
    {
    int a = 98;
    int b = 76;

    if (a>5) {
    cout << "Bucky is AWESOME!!!!";
    }

    return 0;

    I got.

    "Boneless Chicken"

  33. :3

    #include <iostream>
    #include <Windows.h>
    using namespace std;

    int main()
    {
    float a;
    float b;
    float total;

    cout << "Hey Thanks for using my calculator enter two numbers!" << endl;
    cin >> a;
    cout << "Alright, enter a second number" << endl;
    cin >> b;

    total = a + b;

    cout << total << endl << endl;

    if(total==69){

    cout << "Hey You have a dirty mind!" << endl;

    }
    else
    {

    cout << "Alright bud you got it!" << endl;
    }

    system("pause");
    }

  44. i understand that it can be used for >>
    what if if i was supposed to write this
    int a;
    int b;
    int miracle;

    if (a = miracle)

    will the program recognize a word?

  46. #include <iostream>
    using namespace std;
    int main (){
    cout <<" welcome to the world of simple calculations nn";
    int a,b,c,d,e,f,x,y;

    cout << "press 0 to continue or any other no. To quitnn" ;
    cin>> y;

    if (y==0){
    cout << " welcome nn";
    cout << "enter a numbernn";
    cin>> a;

    cout << "enter a another numbern";
    cin>> b;

    cout << " press 1 to add 2 to sub 3 to multiply and 4 to divide" << endl;
    cin>> x;
    }else {
    cout << "goodbye, have a nice day" << endl;
    }
    c = a+b;
    d = a-b;
    e = a*b;
    f = a%b;

    if (x==1){
    cout << "the addition of the nos you entered is" << c << endl;
    }
    if (x==2){
    cout << "the subtraction of the nos you enterd is << d << endl;
    }
    if (x==3){
    cout << "the multiplication of the nos you enterd is << e << endl;
    }
    if (x==4){
    cout << "the division of the nos you enterd is << f << endl;
    }
    if (x>4){
    cout << "goodbye, come back later" << endl;
    }
    return 0;
    }

    I know there are a bit of bugs…but help me with the division…i think thats causing a bit of problem. Anyways, a rough program for simple calculator…rate it please…it would b helpful
