 Posted: Sat Mar 07, 2009 4:36 pm Post subject: First C++ program |
 |
|
This is my first C++ program very simple that I made since starting 3 days ago, I didn't have any good idea's so I thought I might just make this. In addition if anyone can help me add a line in the source that makes the program calculate how many questions you got wrong and right as well as the choice of starting over or not. Here's the code.
| Code: |
//attempting to create a program
#include <iostream>
using namespace std;
int main ()
{
int Iss, Blister;
cout << "Math Practice Beta: Made by FirePhoenix of CEF!\n";
cout << "\nSimply answer a few math questions, to see how good you are at Math!\n";
cout << "\n1. What is 1+1?: ";
cin >> Iss;
if (Iss == 2)
cout << "\nYou are correct!\n";
else
cout << "\nYour wrong.\n";
cout << "\n2. What is 4+4?: ";
cin >> Iss;
if (Iss == 8)
cout << "\nYou are correct!\n";
else
cout << "\nYour wrong!\n";
cout << "\n3. What is 6+6?: ";
cin >> Iss;
if (Iss == 12)
cout << "\nYou are correct!\n";
else
cout << "\nYou are wrong!\n";
cout << "\n4. What is 3+2?: ";
cin >> Iss;
if (Iss == 5)
cout << "\nYou are correct!\n";
else
cout << "\nYou are wrong!\n";
cout << "\n5. What is 4+5?: ";
cin >> Iss;
if (Iss == 9)
cout << "\nYou are correct!\n";
else
cout << "\n You are wrong!\n";
cout <<"\nYou have completed all questions nice job, press any key to close\n";
cin >> Blister;
return 0;
}

Why don't you randomly generate the problems?
Just loop until the user feels like stopping.

god I am rusty on this, virtually forgot c++ or much of any programming,, been a long time lol..
anyway if you want to just edit this program instead of looping you could try making another varible called INT correctsum or whatever you want to call the varible,
then have
if (Iss == 2)
cout << "\nYou are correct!" << correctsum = correctsum + 1 <<\n;
else
else
cout << "\nYour wrong.\n";
you can make varibles to keep a check on the wrong numbers as well in much the same way,
say if there is a wrong answer
INT wronganswer
wronganswer = wronganswer +1
that sort of thing
goodly godly I need a refresher course 
hope that gave you a simple idea or two

Unlimited!, just a few Math Questions
| Code: | #include <iostream>
int main(){
std::cout << "Attempt to calculate the following:\n";
int nr1, nr2, result;
while(true){
nr1 = rand() % 20;
nr2 = rand() % 20;
std::cout << nr1 << " + " << nr2 << " = ";
std::cin >> result;
if(result == nr1 + nr2)
std::cout << "Correct!\n\n";
else
std::cout << "Sorry, the correct answer was: " << nr1 + nr2 << ", try a new one!\n\n";
}
return 0;

Simple, | Code: | //(declarations)
//I prefer using a byte for this particular variable because it takes up less space than an int
byte quesWrong = 0;
//any time the user gets one wrong
quesWrong++; //not sure if a semicolon goes here or not exactly, I don't use this function much. Anyway in case you didn't know adds quesWrong + 1
//at the end of the quiz
cout<<"You got "<<quesWrong<<" wrong."<<endl; |
The code above is from memory and may not exactly be right.

You forgot to ::srand, faulty input will harm your program and I'd prefer for(;;) over while(true). :)

I'm assuming that most if not all compilers would require | Code: | | typedef unsigned char byte |
beforehand, or they could just use | Code: | | unsigned char quesWrong = 0; |

Here are a few of my first programs. while taking the class and following the book of course.
Sources are included, along with an explanation on what they do and how to use them.

An improved version of Anden100's code:
| Code: | #include <iostream>
#include <ctime> //the library for time
#include <cstdlib> //allows usage of srand
using namespace std; //so you don't have to use std:: every time
int main()
{
srand(time(0)); //seeds the random numbers based on the time
system("title Math Problem Generator"); //changes window title
int nr1, nr2, result;
int quesamount = 0, quesnum = 0, queswrong = 0, quesright = 0; //gives odd error if they don't all say = 0 for some reason here.
cout << "How many questions do you want to be asked? ";
cin >> quesamount;
quesamount++; //adds one to quesamount so it asks the right amount
system("cls"); //clears the screen so only the problems display
for(quesnum = 1; quesnum < quesamount; quesnum++) //loops until the question number equals or is above the amount
{
nr1 = rand() % 20 + 1;
nr2 = rand() % 20 + 1; //+ 1 to make sure it never asks with 0(too easy =P)
cout << "Question " << quesnum << ":\n" << nr1 << " + " << nr2 << " = ";
cin >> result;
if(result == nr1 + nr2)
{
cout << "Correct!\n" << endl;
quesright++; //adds to the questions answered right
}
else
{
cout << "Sorry, the correct answer was: " << nr1 + nr2 << ", try a new one!\n" << endl;
queswrong++; //adds to the questions answered wrong
}
}
cout<< "You got " << quesright << " right, and " << queswrong << " wrong." << endl;
system("pause"); //puts Press any key to continue... on screen
return 0;
