Question

****Using C language*****

1. Assume you have an input file with 10 characters. Scan these values into an appropriate array.
2. Convert all the characters into Upper Case, then find their ascii value (like done in the homework) and save to a new array, order these values from highest to lowest. Save to file called “upper.txt”
3. Convert all the characters into Lower Case, then find their ascii value (like done in the homework) and save to a new array, order these values from highest to lowest. Save to file called “lower.txt”
