Name this program filter.c. • The program takes two command line arguments: the name of an input file and the name of an output file. The program should confirm the input and output files can be opened. If a file cannot be opened, print the error message Cannot open file '<filename>' where <filename> is the name of the file and return. o fopen() will return 0 if it fails to open a file. • Then, the program will read the file string by string (up to 50 characters in length). If the string consists of only uppercase and lowercase characters, print it. • You can use isalpha(char) declared in ctype. h to check whether a character is a-z or A-Z. o continue and break might be useful. • Don't forget to close your files! It will likely fail the test cases if files are not closed. Examples ./a.out example.txt output.txt example.txt The Quick Brown Fox Jumps over the Lazy Old Dog. ALABAMA? Roll Tide!!!
