Write a single statement to accomplish each of the following. Assume that each of thesestatements applies to the same program.a) Write a statement that opens the file "oldmast.dat" for reading and assigns the returned file pointer to ofPtr.b) Write a statement that opens the file "trans.dat" for reading and assigns the returnedfile pointer to tfPtr.c) Write a statement that opens the file "newmast.dat" for writing (and creation) and assigns the returned file pointer to nfPtr.d) Write a statement that reads a record from the file "oldmast.dat". The record consistsof integer accountNum, string name and floating-point currentBalance.e) Write a statement that reads a record from the file "trans.dat". The record consists ofthe integer accountNum and floating-point dollarAmount.f) Write a statement that writes a record to the file "newmast.dat". The record consists ofthe integer accountNum, string name and floating-point currentBalance.
Write a single statement to accomplish each of the following. Assume that each of these
statements applies to the same program.
a) Write a statement that opens the file "oldmast.dat" for reading and assigns the returned file pointer to ofPtr.
b) Write a statement that opens the file "trans.dat" for reading and assigns the returned
file pointer to tfPtr.
c) Write a statement that opens the file "newmast.dat" for writing (and creation) and assigns the returned file pointer to nfPtr.
d) Write a statement that reads a record from the file "oldmast.dat". The record consists
of integer accountNum, string name and floating-point currentBalance.
e) Write a statement that reads a record from the file "trans.dat". The record consists of
the integer accountNum and floating-point dollarAmount.
f) Write a statement that writes a record to the file "newmast.dat". The record consists of
the integer accountNum, string name and floating-point currentBalance.
