In this file, we are discussing the concept of a file and only the list of important file handling functions.
CLICK TO DOWNLOAD STUDY MATERIAL -1
It covers opening modes of files, standard function: fopen(), fclose()
CLICK TO DOWNLOAD STUDY MATERIAL -2
In this, I have discussed the topic “how to write into a file using C program” for which used some standard functions: fputc(), fprintf(), fwrite()
CLICK TO DOWNLOAD STUDY MATERIAL -3
In this, Topic discussed is “how to read data from a file using C program” for which used some standard functions: fgetc(), fscanf(), fread()
CLICK TO DOWNLOAD STUDY MATERIAL -4
In this file, we are discussing some other important standard functions: fseek(), ftell(), rewind()
