Let us compile and run the above program that will create a file file.txt with the following content. Initially program creates the file and writes This is tutorialspoint.com but later we had reset the write pointer at 7th position from the beginning and used puts() statement which over-write the file with the following content −

I'm trying to append the contents of a file myfile.txt to the end of a second file myfile2.txt in c. I can copy the contents, but I can't find a way to append. Here's my code: FILE *pFile; FILE *pFile2; char buffer [256]; pFile=fopen ("myfile.txt", "r"); pFile2=fopen ("myfile2.txt", r+); if (pFile==NULL) { perror ("Error opening file."); } else {

Assume that the content of the file test.txt is : test line 1 test line 2 test line 3 test line 4 File I/O; Checking end of file inside a loop condition, bad practice? Closing a file; Copying a file; Flushing a stream; Opening a file; Opening modes; Reading a `struct` from a formatted text file. Reading a file into a container; Reading an ASCII file into a std::string; Reading from a file; Writing files with non-standard locale settings Use an if condition and eof() function that is, end of the file, to ensure the compiler keeps on reading from the file if the end is not reached. Use a break statement to stop reading from the file once the end is reached. Print the contents of variable ch on the console.

The C library function char *fgets (char *str, int n, FILE *stream) reads a line from the specified stream and stores it into the string pointed to by str. It stops when either (n-1) characters are read, the newline character is read, or the end-of-file is reached, whichever comes first. EOF means end of file. It's a sign that the end of a file is reached, and that there will be no data anymore.On Linux systems and OS X, the character to input to cause an EOF is CTRL+D. In the C Programming Language, the exit function calls all functions registered with atexit and terminates the program.

In an executable C program, exactly one .c file has a main() function in while or do/while loops; the third is applied at the end of a loop body.

End Of File returns non - zero value if the end of file (EOF) is encountered and a zero otherwise. The condition can be checked as follows : If (last1.eof ()!=0) {}; fgets returns NULL on end-of-file, when fgets fails you can assume that you've reached the end as this appears to be homework ( you don't need it to be bulletproof). sscanf performs the same operation as fscanf except it reads from buff instead of the file.
