multiple character

Multiple character can be taken either using putc and getc or, by using fscanf and fprintf

Here's the method, we learned earlier by using, putc and getc,

#include <stdio.h>

int main()
{
    FILE* fp;
    char c;

    fp = fopen("file.txt", "w"); // using write mode
    while ((c = getchar()) != EOF) // iterating until EOF
        putc(c, fp); // putting a character
    fclose(fp);

    fp = fopen("file.txt", "r"); // using read mode
    while ((c = getc(fp)) != EOF) // iterating till EOF
        printf("%c", c); // printing to our screen
    fclose(fp);

    return 0;
}

Here EOF is End Of File, can be triggered generally by double pressing ctrl + d in linux or, ctrl + z in windows operating system.
