Question

When you read data in (without using getLine) how is the data read. does it read spaces and line breakers(\n). Also how can you read a paragraph into a double vector of strings ( into words and strings again without using getLine)

Answer 1

When a data is read using getLine, it is generally read over the entire string input separated by space (' '). The input is terminated by a newline character ('\n').

For example - let us assume our input is - "A brown fox is hungry."

Then it can be stored in a array of string as {"A", "brown", "fox", "is", "hungry"}.

Separated by space and terminated by a newline character.

Code to illustrate

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define NUMSTR 3
#define BUFFSIZE 100

int main()
{    
  char *words[NUMSTR];
  char buffer[BUFFSIZE];
  int i, count = 0, slen;

  /* loops only for three input strings */
  for (i = 0; i < NUMSTR; i++)
  {
    printf("Enter a word: ");
    scanf("%s", buffer);
    words[count] = (char *) malloc(strlen(buffer) + 1);
    strcpy(words[count], buffer);
    count++;
  }

  /* reading input is finished, now time to print and free the strings */
  printf("\nYour strings:\n");
  for (i = 0; i < NUMSTR; i++)
  {
    printf("words[%u] = %s\n", i, words[i]);
  }

  return 0;
}
