What will Fopen will return if there is any error while opening a file?
The fopen() function creates a new file when the specified file doesn’t exist and if it fails to open file then it returns NULL. Mode “a”: Using this mode Content can be appended at the end of an existing file.
What does FEOF return in C?
The feof function returns a nonzero value if the end-of-file indicator is set. Otherwise, it returns zero.
How do I printf a new line?
The escape sequence \n means newline. When a newline appears in the string output by a printf, the newline causes the cursor to position to the beginning of the next line on the screen. Some common escape sequences are listed in Fig.
Does printf add new line?
The printf statement does not automatically append a newline to its output. It outputs only what the format string specifies. So if a newline is needed, you must include one in the format string.
What is the need for closing a file in C language?
A file needs to be closed after a read or write operation to release the memory allocated by the program. In C, a file is closed using the fclose() function. This returns 0 on success and EOF in the case of a failure. An EOF is defined in the library called stdio.
What are the first and second arguments of Fopen?
A character string containing the name of the user & the second argument is the mode.A character string containing file pointer & the second argument is the mode.A character string containing the name of the file & the second argument is the mode.All of above.None of these.
How do you open a file in both read and write mode in C?
There are many modes for opening a file:r – open a file in read mode.w – opens or create a text file in write mode.a – opens a file in append mode.r+ – opens a file in both read and write mode.a+ – opens a file in both read and write mode.w+ – opens a file in both read and write mode.
Is Putchar faster than printf?

What is C file data type?
A FILE is a type of structure typedef as FILE. It is considered as opaque data type as its implementation is hidden. We don’t know what constitutes the type, we only use pointer to the type and library knows the internal of the type and can use the data. Definition of FILE is in stdio although it is system specific.
What is Fseek in C?
Description. The C library function int fseek(FILE *stream, long int offset, int whence) sets the file position of the stream to the given offset.
What is %d in printf?
“%s%d%s%d\n” is the format string; it tells the printf function how to format and display the output. … %d tells printf that the corresponding argument is to be treated as an integer value; the type of the corresponding argument must be int .
