Beginner's Guide to C++ Basics

We get to that point, c++, this chapter mainly introduce parts of c++, and understand them with many code example.

hello world

first program "hello world", using std cin and out.

#include <iostream>
int main()
{
    using std::cout;
    using std::endl;// only use the 2 elements in standard namespace
    cout << "Hello Buggy World \n";
    return 0;
}

brief introduction of fuction

first touch of function in c++

#include <iostream>
using namespace std;
int ConsoleOutputTemp();
int main()
{
    ConsoleOutputTemp();
    return 0;
}
int ConsoleOutputTemp()
{
    cout << "this is a simple string literal" << endl;
    cout << "number 5 " << 5 << endl;
    cout << "math problem 10/5 " << 10 / 5 << endl;
    return 0;
}

## first glance at 'return value' return values using function

#include <iostream>
#include <string>
using namespace std;
int FuncInputDemoOne();
int main()
{
    return FuncInputDemoOne();
}
int FuncInputDemoOne()
{
    int inputNumber;
    string inputName;
    cout << "enter an integer " << endl;
    cin >>inputNumber;
    cout << "enter your name " << endl;
    cin >> inputName;
    cout << inputNumber << " " << inputName << endl;
    return 0;
}
