too few arguments to function 'int getc(FILE*)'

This error message occurs when the function `getc()` is called with too few arguments. The `getc()` function is used to read a single character from a file. It requires one argument, which is a pointer to the `FILE` object representing the file being read.

To fix this error, make sure that the `getc()` function is called with the correct number of arguments, including the `FILE` pointer. For example:

FILE* file = fopen("myfile.txt", "r");
int c = getc(file);

In this example, the `FILE` pointer `file` is passed as the argument to `getc()`, allowing the function to read a character from the file.
