How can I solve this problem. I've tried my very best but I can't
#include<iostream.h>
#include<iomanip.h>
int hours=3, hh, mm;
void firstorder();
void firstserve();
int main(){
int time;
cout<<"The first customer arrived at "<<firstorder<<endl;
cout<<"The first customer was served at "<<firstserve<<endl;
return 0;
}
int firstorder(int){
int mint;
hh= mint/ 60;
mm= 0 %60;
cout<<hours<<":"<<setw(2)<<setfill('0')<<mm<<'\n';
return mm;
}
int firstserve(int){
int mint;
hh= mint/ 60;
mm= 2 % 60;
cout<<hours<<":"<<setw(2)<<setfill('0')<<mm<<'\n';
return mm;
}
