Rita        Johnson     91.50 A
Randy       Brown       85.50 B
Seema       Arora       76.50 C
Samir       Mann        73.00 C
Samantha    McCoy       88.50 B

The preceding program works as follows. The statements in Lines 8 to 13 declare and initialize variables needed by the program. The statements in Lines 14 and 15 declares 'inFile' to be an 'ifstream' variable and 'outFile' to be an 'ofstream' variable. The statement in Line 16 opens the input file using the variable 'inFile'. If the input file does not exist, the statements in Lines 17 to 21 output an appropriate message and terminate the program. The statement in Line 23 sets the output of floating-point numbers to two decimal places in a fixed form with trailing zeros.
