void hex2str(int value, char& str);

int a = 0x1014;
int b = 0x7FFF;

char cstr1[8], cstr2[8];
hex2str(a, cstr1);
hex2str(b, cstr2);

Now these two char arrays are:

cstr1[] == {'1', '0', '1', '4', '\0', ...}

cstr2[] == {'7', 'F', 'F', 'F', '\0', ...}

Have no idea, how to achieve that. Any help?

why can't you use `snprintf()`? – Sourav Ghosh Sep 08 '16 at 16:10

Pick **a** (one) language. – WhozCraig Sep 08 '16 at 16:11
The C and C++ are two different languages and in this case yield different answers to your question. For example, in C++ you can use `ostringstream` and the `hex` manipulator. The C language does not have this capability. So choose, C or C++. – Thomas Matthews Sep 08 '16 at 16:24
