Reads in a string from this file. The string has been encoded using a modified UTF-8 format. The first two bytes are read, starting from the current file pointer, as if byreadUnsignedShort. This value gives the number of following bytes that are in the encoded string, not the length of...
Reads a boolean from this file. This method reads a single byte from the file, starting at the current file pointer. A value of 0 represents false. Any other value represents true. This method blocks until the byte is read, the end of the stream is detected, or an exception is thrown...
In this program, we are writing characters (by taking input from the keyboard) to the file until new line is not pressed and reading, printing the file. #include<stdio.h>intmain(){FILE*fp;/* file pointer*/charfName[20];charch;printf("\nEnter file name to create :");scan...
FILE *fptr; // Open a file in read mode fptr = fopen("filename.txt","r"); // Store the content of the file charmyString[100]; In order to read the content offilename.txt, we can use thefgets()function. Thefgets()function takes three parameters: ...

This example gets a line of input from thestdinstream. You can also usegetc(stdin)instead ofgetchar()in theforstatement to get a line of input fromstdin. #include <stdio.h> #define LINE 80 int main(void) { char buffer[LINE+1]; int i; int ch; printf( "Please enter string\n" )...
