Read in enough to fill your buffer, then dump your buffer to the screen, clear it out, and repeat until you get to the end of the file. First, don't use scanf.
Use fgets which takes a parameter to specify the buffer size, and which leaves any newline characters intact. A simple loop over the file that prints the buffer content should naturally copy the file intact.
Second, use fread or the common C idiom with fgetc. These would process the file in fixed-size chunks or a single character at a time.
If you must process the file over white-space delimited strings, then use either fgets or fread to read the file, and something like strtok to split the buffer at whitespace.
Don't forget to handle the transition from one buffer to the next, since your target strings are likely to span the buffer boundary. If there is an external requirement to use scanf to do the reading, then limit the length of the string it might read with a precision field in the format specifier.
If single strings longer than your buffer are allowed, then you would have to process them in two pieces.
If not, you have an opportunity to tell the user about an error politely without creating a buffer overflow security hole. Regardless, always validate the return values and think about how to handle bad, malicious, or just malformed input.Write a Java program to check if two String are anagram of each other, is another good coding question asked at fresher level Java Interviews.
A "Hello, World!"program is a computer program that outputs or displays the message "Hello, World!". Because it is very simple in most programming languages, it is often used to illustrate the basic syntax of a programming language and is often the first program people write.

JFlex is a lexer/scanner generator for Java, written in Java, with emphasis on Unicode support, speed and platform independence. In these Java exercises and solutions you will practise Java loops: for loop while loop and do while loop to do repeated work. Write a program in C++ programming language to print ASCII value of a character and all alphabets using for loop and sample input and output.
