 Assume a text console where somebody is typing input. Whenever the person hits enter, we should display the string that he has entered. The string can be very very long and the program that takes the input and displays should be as fast as possible. Write such a C program1 AnswerThe easy solution would be start with a buffer and whenever it is filled reallocate the buffer to 2*size. But I actually came up with a better solution that doesn't need the overhead of reallocation. I used a recursive function with the buffer size increasing by a multiple of 2 every time the function is called. When user hits enter, the function returns and on return-ing displays the characters in each buffer.
