Unexpected output in c++ code , Not getting expected result -

i made program show possible time in clock if angle given between hour , minute hand ..

#include <iostream> #include <fstream> #include <string> #include <vector> #include <math.h> using namespace std;  int main(){      //ifstream cin("input.txt");     vector <float> hour , min , angle;     string str;     int h , m ;      float diff, cal1 ,cal2 ,  , j;;     h = 11 ;     m = 59;     ( = 0 ; <= h ; i++ ){         ( j = 0 ; j <= m ; j = j + 1){             cal1 = (i*60/2) + (j/2); // hour angle             cal2 = (j*6); // min angle;             diff = fabs(cal1 - cal2) ;             if ( diff > 180 ){                 diff = 360.0000 - diff ;             }             //cout << cal1 << " " << cal2 << " " << diff << endl;              hour.push_back(i);             min.push_back(int(j));             angle.push_back(diff);         }     }      int t , value , size;     cin >> t;     size = hour.size();     while( t-- ){         cin >> value;          ( int = 0 ; < size;i++ ){             //cout << angle[i] << endl;             if ( value == angle[i] ){                 if ( hour[i] > 9 && min[i] > 9 ){                     cout << hour[i] <<":" << min[i] << endl;                 }                 else if ( hour[i] <= 9 && min[i] > 9 ){                     cout << "0" << hour[i] <<":" << min[i] << endl;                 }                 else if ( hour[i] > 9 && min[i] <= 9 ){                     cout << hour[i] <<":" << "0" << min[i] << endl;                 }                 else {                     cout << "0" << hour[i] <<":" << "0" << min[i] << endl;                 }             }         }     } } 

for reson when puts input :

    2     60.0000     30.0000 

i gets

   02:00    10:00    00:00 

but should

    02:00     10:00     01:00     11:00 

and when enter input

2 30.0000 60.0000 

i gets

    01:00     11:00     00.00 

when remove 0 in input , gives intergers shows correct answer floats gives wrong answer . ran code in ideone . gave same problem .

value has data type int input demands float:

try replacing int value float value
