How do I sort an array while using a class?

My code:

#include #include using namespace std;

class dancer { int id, hrs; float rate; public: dancer(); void read(ifstream &); void print(ofstream &); void sort_id(dancer a[], int);

dancer::dancer() { }

void dancer::read(ifstream &infile){ infile >> id >> hrs >> rate; } void dancer::print(ofstream &outfile){ outfile << id <<" "<< hrs<<" "<< rate <<" "; } void dancer::sort_id(dancer a[12], int n) //This is the important part where I seek help. { for (int b = 0; b < n - 1; b++) { for (int c = 0; c > b - n - 1; c++) { if (a[n] > a[b - 1]) { int temp = a[n]; a[b] = a[b + 1]; a[b + 1] = temp; } } } }

int main() { dancer a[12];

ifstream infile; ofstream outfile; infile.open("indata.txt"); outfile.open("outdata.txt");

for (int i = 0; i <= 11; i++) { a[i].read(infile); }

sort_id();

for (int j = 0; j <= 11; j++) { a[j].print(outfile); } infile.close(); outfile.close(); system("pause"); return 0; }
