• getc(): it reads a character from a file.
• putc(): it writes a character to a file.
• fscanf(): it reads a set of data from a file.
• fprintf(): it writes a set of data to a file.
• getw(): it reads an integer to a file.
• putw(): it writes an integer to a file.
• fseek(): it is used to set the position to aspiration point.
• ftell(): it is used to give present position in the file.
• rewind(): it set the position to the starting point.

Example:

#include <stdio.h>
#include <stdlib.h> 

void main()
{
	FILE *fp;
	char c;
	fp=fopen("TEST.txt","r");
	while(1){
		c=fgetc(fp);
		if(feof(fp))
			break;
		printf("%c",c);
	}
	fclose(fp);
}
