Question

RUN THIS CODE THEN ANSWER THE FOLLOWING:

1. HOW CAN I USE while(!inFile.eof()) IN THIS PROGRAM INSTEAD OF while (transCode != 0)?

2. HOW CAN I PRINT THE OUTPUT TO THE   checkOut.dat FILE?

3. HOW CAN I DISPLAY THE NUMBER OF TRANSACTIONS IN THE FILE? (AS IN BY CREATING A COUNTER OF EVERY TRANSACTION).

4. THIS IS THE checkIn.dat file data

2000 1 1225.72 1 463.81 3 200 1 632 2 1500 1 300 2 1800 0 (note that 2000 is the beginning bal, 1,3,2 are transaction code folloed by actual amount)

Explanation / Answer

1) used while(!inFile.eof()) in the program

2) output the results onto file ( replace every cout with fileoutput )

3) added no of transaction
