Hya, 
and thanx agian for helping me. I certainly understood a bit about
functions, 
but still not enough to resolve another stumbling block (for me).
   Could u plz have a look a it and point me out, how I should do it?
Below is the piece that I working on. The first function is working, but
there something wrong with data types or formats. It prints everything,
except for the last interger. If u r interested to see the whole thing,
just scroll down, plz.
Thank you - I really do appreciate, Alex 




#include <stdio.h>
#include <conio.h>
void prompt(int &hrs1, char &ch1, int &mnts1,int &hrStop1,int 
&mntStop1)
 {
 printf ("Plz carve your nums");
 scanf  ("%d%c%d", &hrs1, &ch1, &mnts1);
  printf("U left office at: ");
  scanf ("%d%c%d", &hrStop1, &ch1, &mntStop1);
  return;
 }
void mntpositive(int &hrs1, int &hrStop1, int &Allhrs1)
{
	if (hrs1>=8&&hrs1<=12&&hrStop1<8&&hrStop1>0)//began before 12 &
finished after
	    Allhrs1=12-hrs1;
	    Allhrs1=Allhrs1+hrStop1;
	   if (hrs1>=8&&hrs1<12&&hrStop1>=8&&hrStop1<=12)//began & finished
before 12
	     Allhrs1=hrStop1-hrs1;
	   else if (hrs1<7&&hrs1>0&&hrStop1<=7&&hrStop1>0)//began & finished
after 12
	   Allhrs1=hrStop1-hrs1;
	   return;
}
void main (void)
 {   int days, Allmnts, totalHrs, Allhrs, totalMnts;
 char ch;


      clrscr();
       int hrs, mnts, hrStop, mntStop;

       prompt(hrs, ch, mnts, hrStop, mntStop);



   if (mnts<60&&mnts>=0&&mntStop<60&&mntStop>=0)//minutes are valid
initially

       Allmnts=mntStop-mnts;

  if (Allmnts>=0&&Allmnts<60&&mntStop>=mnts)//entries with positive
minutes difference
	{int hrs, hrStop, Allhrs;
	  mntpositive(hrs, hrStop, Allhrs);
	   }
	   printf("\n\tHere they are:\n\t%d and %d and %d and %d and %d", hrs,
mnts, mntStop, hrStop, Allhrs);
	   }






And here's the whole program, if it's helpful .

#include <stdio.h>
#include <conio.h>

&mntStop1)
 {
 printf ("Plz carve your nums");
 scanf  ("%d%c%d", &hrs1, &ch1, &mnts1);
  printf("U left office at: ");
  scanf ("%d%c%d", &hrStop1, &ch1, &mntStop1);
 }


int main ()
 {  int hrs, mnts, hrStop, mntStop, Allhrs, Allmnts, days, totalHrs=0,
totalMnts=0, extra;
 char ch;

     for (days=0; days<5; days++)
    {    clrscr();
       int hrs, mnts, hrStop, mntStop;
       char ch;
       prompt(hrs, ch, mnts, hrStop, mntStop);



   if (mnts<60&&mnts>=0&&mntStop<60&&mntStop>=0)//minutes are valid
initially

       Allmnts=mntStop-mnts;

  if (Allmnts>=0&&Allmnts<60&&mntStop>=mnts)//entries with positive
minutes difference
	{

	if (hrs>=8&&hrs<=12&&hrStop<8&&hrStop>0)//began before 12 & finished
after
	    Allhrs=12-hrs;
	    Allhrs=Allhrs+hrStop;
	   if (hrs>=8&&hrs<12&&hrStop>=8&&hrStop<=12)//began & finished before
12
	     Allhrs=hrStop-hrs;
	   else if (hrs<7&&hrs>0&&hrStop<=7&&hrStop>0)//began & finished after
12
	   Allhrs=hrStop-hrs;
	   }
     else if (Allmnts<0&&Allmnts>-60)//entries with a negative minutes
difference
       {
	 if (hrs>=8&&hrs<=12&&hrStop<8&&hrStop>0)//began before 12 & finished
after
	    Allhrs=11-hrs;
	    Allhrs=Allhrs+hrStop;
	   if (hrs>=8&&hrs<=12&&hrStop>=8&&hrStop<=12)//began & finished before
12

	     Allhrs=hrStop-hrs-1;
	   else if (hrs<8&&hrs>0&&hrStop<8&&hrStop>0)//began & finished after
12
	   Allhrs=hrStop-hrs-1;
	   Allmnts=60+Allmnts;
	  }


	     totalHrs=totalHrs+Allhrs;
	     totalMnts=totalMnts+Allmnts;
	  }

	    float rate, hrWage, mntWage, regWage, SuperWage, totalWage;

	      printf ("Enter desired pay per hour: ");
	      scanf  ("%f", &rate);

	 if (totalMnts>=60)
	  {
	    extra=totalMnts/60;
	    totalMnts=totalMnts%60;
	    totalHrs=totalHrs+extra;
	    }




       if (totalHrs>40)
	 { regWage=rate*40;
	   SuperWage=(totalHrs-40)*1.5f*rate;
	   mntWage=(rate/60)*totalMnts;
	   totalWage=regWage+SuperWage+mntWage;
	   }
	else
	  {
	     SuperWage=0;

	     mntWage=(rate/60)*totalMnts;
	     totalWage=(rate*totalHrs)+mntWage;
	   }
	printf ("\n\tYour regular pay is $%7.2f,\n overtime pay $%7.2f,\n\t and
total pay $%7.2f\n\t", regWage, SuperWage, totalWage);
    return 0;
   }
