Hi @rusahupe, it's nice of you to want to help out ##-## I'm not a Mentor/Moderator here, but given that you're new here, I'd like to gently point out that there are rules on the Physics Forums that place some carefully-thought-out limits on how members may help with homework, and it seems to me that simply writing the code for someone, without first seeing a genuine attempt from that someone, might be out of bounds ##-## you can read the rules at the Terms link in the footer of every page, and if you're unsure about something, you can PM one of the Mentors . . .rusahupe said:Please reply If you want me to write the code for you.
C: Question on file handling refers to the topic of handling files in the C programming language. It involves reading, writing, and manipulating files on a computer's file system.
To open a file in C, you can use the fopen() function. This function takes in two arguments: the name of the file and the mode in which you want to open the file (e.g. read, write, append). It returns a file pointer which can be used to perform operations on the file.
To read from a file in C, you can use the fscanf() or fgets() functions. These functions take in the file pointer and the data type of the variable you want to read the data into. They will read data from the file and store it in the specified variable.
To write to a file in C, you can use the fprintf() or fputs() functions. These functions take in the file pointer and the data you want to write to the file. They will write the data to the file at the current position of the file pointer.
To close a file in C, you can use the fclose() function. This function takes in the file pointer and closes the file. It is important to close files after you are done using them to avoid any data loss or corruption.
