What is tell () in Python?
Python File tell() Method The tell() method returns the current file position in a file stream.
Tip: You can change the current file position with the seek() method..
Which operator is used to insert the data into file?
1. Which operator is used to insert the data into file? Explanation: You can write information to a file from your program using the stream insertion operator <<. 2.
How do you use Fputs?
C Language: fputs function (Write String from File)Syntax. The syntax for the fputs function in the C Language is: int fputs(const char *s, FILE *stream); … Returns. The fputs function a nonnegative value if it is successful. … Required Header. In the C Language, the required header for the fputs function is: #include
What is the function rewind () do?
In the C Programming Language, the rewind function sets the file position to the beginning of the file for the stream pointed to by stream. … It also clears the error and end-of-file indicators for stream.
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.
Which mode is used to truncate the file?
To truncate the file, you can open the file in append mode or write mode.
What is the return value of GETC ()?
It is the simplest function to read a file. Like getchar, getc() may be implemented macro instead of function. getc is equivalent to fgetc. getc returns the next character from the stream referred to by fp; it returns EOF for End Of File or error.
What is fwrite in C?
Description. The C library function size_t fwrite(const void *ptr, size_t size, size_t nmemb, FILE *stream) writes data from the array pointed to, by ptr to the given stream.
Is used to show hierarchy in a pseudo code?
4. ______________ is used to show hierarchy in a pseudo code. Explanation: Each design structure uses a particular indentation pattern. … Explanation: The READ statement is used to take the input.
Does Fputs add new line?
Notice that fputs not only differs from puts in that the destination stream can be specified, but also fputs does not write additional characters, while puts appends a newline character at the end automatically.
How do you use fread?
Syntax: size_t fread(void *ptr, size_t size, size_t n, FILE *fp); The ptr is the starting address of the memory block where data will be stored after reading from the file. The function reads n items from the file where each item occupies the number of bytes specified in the second argument.
What is rewind Stdin?
rewind is a function in the C programming language that is specified in the stdio. h library header file. The function moves the file position indicator to the beginning of the specified stream, while also clearing the error and EOF flags associated with that stream.
What is the function of f tell?
In the C Programming Language, the ftell function returns the current file position indicator for the stream pointed to by stream.
What is Fseek and Ftell in C?
fseek(), ftell() and rewind() fseek() – It is used to moves the reading control to different positions using fseek function. ftell() – It tells the byte location of current position in file pointer. rewind() – It moves the control to beginning of a file.
Which of the following is true about file FP?
Question 1 Explanation: fp is a pointer of FILE type and FILE is a structure that store following information about opened file. Question 2 Explanation: fopen() returns NULL if it is not able to open the given file due to any of the reasons like file not present, inappropriate permissions, etc.
Which type of files can’t be opened using f open?
Discussion ForumQue.Which type of files can’t be opened using fopen()?b..binc..cd.none of the mentionedAnswer:none of the mentioned1 more row
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?
C library function – fseek() The C library function int fseek(FILE *stream, long int offset, int whence) sets the file position of the stream to the given offset.
