Practice problems + Solutions

Hello fellow members,
I know there are million others who are out of ideas to code, like me. After a little bit of searching, I have found a link in which it contains some C++ exercises and solutions for those exercises. Remember that the exercises are arranged from difficulty; If you want the hard ones, scroll all the way to the bottom.

Ordered based on difficulty(really easy for beginner programmers): http://en.wikibooks.org/wiki/C++_Program...Iterations

A lot of exercises!: http://en.wikibooks.org/wiki/C%2B%2B_Pro.../Exercises

Not ordered in any way: http://www.fz-juelich.de/video/cpp/html/exercises.html

The most famous, ProjectEuler: http://projecteuler.net/index.php?section=problems

I hope you found this helpful. Please if you have any ideas or websites which contains some programming ideas, feel free to post them.

Thanks for reading,

Dynamic Database - ProjectEuler + Solution

Hello fellow members,

Before you talk about SQL connection and stuff, this has nothing to do with that.

My friend gave me an assignment to do this:

Code:

Make a program like this:
1. Add to database
2. Display databse
Option:

You should be able to add as many databases as you want. It should ask you for name, age, gender, and after it is registered, put the computer time in a string(which should be a string or whatever). All this information should be taken into a structure

When displaying the database, it should display like this:
--
<The registered time>
Name: Name
Age: 15
Gender: M

The 'Display database' option should print all the databases added.

I know this source code sucks, leave me alone:

Code:

#include <iostream>
#include <string>
#include <ctime>

int counter = 0, option = 0;

struct data_base
{
    std::string name;
    int age;
    char gender;
    std::string curtime;
};

int main()
{
    data_base **array = new data_base*;
    data_base *data = new data_base;
    while(1)
    {
        system("CLS"); //don't care
        std::cout << "1. Append to Database\n2. Display Database\nChoose(1/2):";
        std::cin >> option;
        if(option == 1)
        {
            data = new data_base;
            system("CLS"); //don't care
            std::cout << "Enter the name: ";
            std::cin.ignore();
            std::getline(std::cin, data->name);
            std::cout << "Enter the Age: ";
            std::cin >> data->age;
            std::cout << "Enter the gender: ";
            std::cin >> data->gender;
            while(data->gender != 'm' && data->gender != 'M' && data->gender != 'f' && data->gender != 'F')
            {
                std::cout << "\nEnter the correct gender type\n";
                std::cout << "Enter the gender: ";
                std::cin >> data->gender;
            }
            time_t raw_time;
            tm *time_info;
            time(&raw_time);
            time_info = localtime(&raw_time);
            data->curtime = asctime(time_info);
            array[counter] = data;
            counter++;
        }
        else if(option == 2)
        {
            system("CLS"); //don't care
            int c = 0;
            while(c < counter) //problem is heere
            {
                std::cout << "\n--\n";
                std::cout << "Time appended: " << array[c]->curtime << std::endl;
                std::cout << "Name: " << array[c]->name << std::endl;
                std::cout << "Age: " << array[c]->age << std::endl;
                std::cout << "Gender: " << array[c]->gender << std::endl;
                c++;
            }
            std::cin.ignore();
            std::cin.get();
        }
        else
        {
            std::cout << "Can you read?";
        }
    }
    std::cin.ignore();
    std::cin.get();
    return 0;
