I need help with file pointers

Question

I need to write a program with these components and I just don’t know where to start. I’m new in this and need help lol

Declares a FILE pointer, char filename[100] and any additional variables needed

Prompts user to enter the filename “declaration.txt”

Prints the name of file entered

Opens the tile as read only

If the file pointer is nil invokes exit (0)

Contains the function
Int isvowel(char c) which you must write that returns 1 if the character is a vowel 0 otherwise

In a loop, if a vowel is input via
C= fgetc(fptr)
Print it, otherwise no action Is taken
Then read the next character until EOF is encountered at which point the program is exited
