Formatting in c++

is there any way to remove the zero before the decimal point?
instead of 0.33
it would print .33

sure, use:

Code:

---

cout << ".33";

---

poorly stated questions give you poor answers.

however, here is an alternative:

Code:

---

#include<iostream>
#include<sstream>

using namespace std;

int main()
{

        float x = 0.33;
        stringstream ss;
        ss << x;
        cout << ss.str().substr(1,ss.str().length()) << endl;
}

---

maybe create a function that takes in a float and returns the string with the leading character (assumed to be a zero) removed?

Code:

---

std::string a("0.33");

a = a.substr(a.find("."));

---

What about input such as 10.23 or 1023?

Code:

---

    std::size_t pos = a.find('.');
    if (pos == 1 && a[0] == '0') {
        a = a.substr(pos);
    }

---

This might also have locale issues (e.g where , is used for decimal point).

If C++ accepts ".33" as input for a double then it is a legitimate question whether there is a format flag that lets you output without leading 0 too (I don't know of that).
