What is a file pointer?
A file pointer is an opaque object that refers to a file. Opaque means that you should not attempt to delve into its specific value, other than to use it as a file pointer. FILE *fp; /* fp is the file pointer */ fp = fopen("somefile.txt"); if (fp == NULL) ...{exception}... fprintf(fp, "Hello somefile.txt"); fclose(fp);

What function will read a specified number of elements from a file?
The function fread() in C can be used to read a specified number of elements from a file. It takes as arguments the pointer to the buffer, size of each element, number of elements to read, and the file pointer.
What does the file pointer return?
The file pointer, often used in programming to manage file input and output, returns the current position within a file. It indicates where the next read or write operation will occur. Depending on the context, it can also provide information about the file's end, allowing for efficient data processing and manipulation. Functions or methods associated with file pointers can typically move or adjust this position as needed.
