how to convert an int to a char C++ -

im having trouble assignment have convert 3 variables of clock (int hour, int minutes, , bool afternoon) converted string in method. tried converting int char , replacing each string char. function suppose return t/f if conversion worked or not. here have far:

class time { private:   int hour;   int minutes;   bool afternoon; public:   void sethour(int hr);   void setminutes(int min);   void setafternoon(bool aft);    int gethour();   int getminutes();   bool getafternoon();    bool setasstring(string time);   string getasstring();    time(void);   ~time(void); }; 

and

bool time::setasstring(string time){ char min = minutes; char hr = hour;  char hr[0] = time[0]; char hr[1]= time[1]; char min[0] = time[3]; char min[1] = time[4]; char afternoon = time[6]; if ((hourtens > 1) || (mintens > 5)) { return false; } else { return true; } } string time::getasstring(){ return false; } 

it straight-forward in fact, may involve little twist in mind @ first.

i not going give actual code, snippet that, if can understand them, should able solve problem yourself:

what want converting integer string/char. basic thing need convert single digit int corresponding char.

// example have such integer int = 3;  // , want convert char char c = '3'; 

what need is, adding '0'. reason why works because '0' means integer value of 48. '1'..'9' means 49..57. simple addition find out corresponding character single decimal digit integer:

i.e. char c = '0' + i;

if know how convert single decimal digit int char, what's left how can extract individual digit more-than-one-decimal-digit integer

it simple math making use of / , %

int = 123 % 10;  // give u last digit, 3 int j = 123 / 10;  // give remove last digit, 12 

the logic left homework need then.
