What is the use of FEOF () function in code?
The feof() function in PHP is an inbuilt function which is used to test for the end-of-file on a file pointer. It checks if the “end-of-file” has been reached or not.
Can u rely on FEOF () function to read from files that are written using binary mode?
1 Answer. You should not use feof() to loop on – instead, use the return value of fread() – loop until it returns zero. This is easy to see if you consider reading an empty file – feof() returns the EOF status AFTER a read operation, so it will always try to read bogus data if used as a loop control.
Can you rely on FEOF () function to read from files that are written?
feof () function finds end of file. fgetchar () function reads a character from keyboard. fprintf () function writes formatted data to a file. fscanf () function reads formatted data from a file.
What is FEOF function in C?
C feof function is used to determine if the end of the file (stream), specified has been reached or not. This function keeps on searching the end of file (eof) in your file program. C feof function returns true in case end of file is reached, otherwise it’s return false.
What argument does the FEOF function take when it is called to test for the end of file?
The feof() function takes a file stream as argument and returns an integer value which specifies if the end of file has been reached.
What does FEOF () return if end-of-file was reached?
The function feof() is used to check the end of file after EOF. It tests the end of file indicator. It returns non-zero value if successful otherwise, zero.
What argument does the FEOF function take when it is called to test for the end-of-file?
What happens when an end-of-file condition is encountered while reading characters using getchar function?
EOF is a special character used in C to state that the END OF FILE has been reached. Usually you will get an EOF character returning from getchar() when your standard input is other than console (i.e., a file). Then your getchar() will return every single character in somefile and EOF as soon as somefile ends.
How do you write and read operations performed on file explain with suitable C program?
We must open a file before it can be read, write, or update. The fopen() function is used to open a file. The syntax of the fopen() is given below….Opening File: fopen()
| Mode | Description |
|---|---|
| w | opens a text file in write mode |
| a | opens a text file in append mode |
| r+ | opens a text file in read and write mode |
