The fscanf () function works as scanf (). The difference is that fscanf () reads a file and not the computer keyboard. prototype: [Read more…] about C Program to Text file containing prime numbers in a given range

If a character read from an input stream is not appropriate for the current operation, we can push it back to the stream using the ungetc function. A subsequent character read operation (such as fgetc or getc) on that stream will return this character. The prototype of the ungetc function is given below. [Read more…] about The ungetc Function in C

The fgets function reads a sequence of character, i. e., a character string from an input stream. Its prototype is given below. [Read more…] about The fgets and fputs Functions in C

The fputc function and putc macro are used to write a character to an output stream. Their prototypes are given below. [Read more…] about C program to fputc Function and the putc Macro

Let us use a while loop in conjunction with the getc macro to read a text file character by character as explained in Program. The counting of characters and lines is very straight forward, the code for which is given below. [Read more…] about C program to count the number of characters, words and lines in a text file

When I/O operations on a file are complete, we must close the file using the fclose function. The prototype of this function is as follows: [Read more…] about The fclose Function in C

The devices used with a computer, such as a keyboard, monitor, printer, hard disk, magnetic tape, etc., have widely varying properties regarding data input and output. To simplify data I/O operations, the C standard library supports a simple mode of input and output based on the concept of a stream. [Read more…] about What is Streams?
