fgetc() is used to obtain input from a file single character at a time. This function returns the ASCII code of the character read by the function. It returns the character present at position indicated by file pointer. After reading the character, the file pointer is advanced to next character.
What is the difference between fgets and fgetc?

What does fgetc return on end-of-file?
Return Value

Does fgetc move the file pointer?
fgetc() function in C
fgetc() function is a file handling function in C programming language which is used to read a character from a file. It reads single character at a time and moves the file pointer position to the next address/location to read the next character.
Is fgetc slower than fgets?
Although fgetc() also works, it is marginally fiddlier – but only marginally so. Underneath the covers, it uses the same mechanisms as fgets() . The internals may be able to exploit speedier operation – analogous to strchr() – that are not available when you call fgetc() directly.
Why is fgets better than gets?
Even though both the functions, gets() and fgets() can be used for reading string inputs. The biggest difference between the two is the fact that the latter allows the user to specify the buffer size.
What is fgets and Fputs in C?

What is the purpose of file type in file handling?
File Handling In C++
Files are used to store data in a storage device permanently. File handling provides a mechanism to store the output of a program in a file and to perform various operations on it.
What is rewind in C?

What does PUTC do in C?
The putc() function converts c to unsigned char and then writes c to the output stream at the current position. The putchar() is equivalent to putc( c , stdout) . The putc() function can be defined as a macro so the argument can be evaluated multiple times.
