For many purposes, i need to take a large input of string.
I have declared a character array in large size. But i cannot take
more than 128 characters input as string from keyboard.
Can anyone help me about htis problem ?

Why don't you provide a simple test case to show how do you exactly fail to read more than 128 bytes?
You could also read some manual, but I'm sure you have already done it. You wouldn't ask before reading it, would you?

u can try this for reading a line of unlimited size, with dynamic allocation:
Code: Select all
#include <stdio.h>
#include <stdlib.h>
const int BLOCK = 16;
char *getline(void) {
char *p, *s = NULL;
int c, lim = -1, size = 0;
while ((c = getchar()) != EOF) {
if (size >= lim)
if (!(p = realloc(s, (lim+=BLOCK)+1))) {
ungetc(c, stdin);
break;
} else s = p;
if ((s[size++] = c) ==
