file input and output

[e15slicks]

Can someone help me i am trying to create a program where it reads the text file from a user and opens the text file for input 1. counts the number of characters in the file,
2. counts the number of letters in the file
3. counts the number of vowels in the file
4. counts the number of consonants in the file
5. computes the % of letters in the file
6. computes the % of vowels in the file
7. computes the % of consonants in the file
8. reads a second text file name, different from the first from a user
9. opens the second file for output
10. writes the counts and percentages, well-formatted and well-labeled, to the second file
11. closes the input file
12. close the output file
....

i created a program already but something is wrong with it. when i run the program it sends me to the else statement and then it shuts down on me can someone help me to tell me what am i doing wrong..
