C++学习札记一

主要是根据C++来说 发现\b退格的用处 以及const的应用 写博客有点累啊

// bondini.cpp -- using escape sequences
#include 
int main()
{
    using namespace std;  
    cout.setf(ios_base::fixed, ios_base::floatfield);//fixed-point
    cout << "Please enter your height in inches: ___\b\b\b ";//这个体现的就是退格的思想
    int inch; double infeet;
    cin >> inch;
    const int convert = 12;
    infeet = (double)inch / convert;
    cout << "This person height is " << inch << endl
        << infeet << endl;
    return 0;
}

运行结果

对比一下
