Question

I have an int and I would like to convert it to a vector<char>.

For example:

std::vector<char> MyVct;
int i = 2046;

So I want a vector of size 4 which will have:

MyVct[0] = '2';   
MyVct[1] = '0';   
MyVct[2] = '4';   
MyVct[3] = '6';  

How can I do it in the most efficent way ?

Answer 1

Do this:

if (n == 0) { MyVct.push_back('0'); }

else { for ( ; n; n /= 10) { MyVct.push_back('0' + (n % 10)); } }

std::reverse(MyVct.begin(), MyVct.end());
