Exit the program the output file the output file cannot open

Quotient throws an exception to the higher-level function main to decide whether or not the program should be terminated. Main catches the divByZero and prints out an appropriate comment on the screen. Also include in main a try block to catch the divide-by-zero error.

If no exception occurs, print out a message "The quotient is xxxxx."

3. Create an ASCII (or text) file that contains text that will be used as input to your program. Call this file textinput.

4. Have the output stored in a file called textouput.

6. • Whenever a nonblank character is found, it calls the function that does the counting, characterCount, to update the letter count. (Do not count blank, tab, or end-of-line characters as part of the letter count.)

   • Have the characterCount function convert the letter to uppercase, find the index of the array corresponding to this letter and, if the index is valid, increment appropriate count.

   • 4. Open the output file.

     5. If the output file cannot open, exit the program.

     10. Increment the line count. (Increment the variable lineCount.)

     11. Read the next character.
