RE: [Dev-C++] Dynamic Storage or Sentences

Alright, what you need here is called the C++ vector class, which is an
endless array that reallocates itself when it runs out of space.
 
It's in the <vector> header.
 
Then you can go:
 
vector<string> v; v.reserve(numSentences); v.push_back(sentence);
 
It automatically sets its length. So v.length() can be used as a limit in
loops.
And it supports []. So you can for-loop through the contents.

Subject: [Dev-C++] Dynamic Storage or Sentences


Hi, all!
 
I am trying to develop a program to store sentences in an array as you can
see below. I am following the steps: 1) Ask the user the number of
sentences; 2) Given the number of sentences, ask the user to enter Sentence
1 to Sentence n. 
 
As can be seen in my code, if the user enter 10. I will get a char
array[10]. I was trying to store the sentences like: array[0] = "sentence
1"... array[n] ="sentence n", but that was stupid. Because I was trying to
put a sentence in the place of a character. 
 
If I use a pointer to the array maybe I can solve this, but how can a put a
pointer for each sentence generically for afterwards reach them????? With 10
sentences I will need 10 pointers for 10 arrays!!!!
 
Any suggestions!
 
Best,
 
Alex.
 
PS: You can perfectly compile the source but it is not working properly of
course.

/* Storing sentences dynamically in a array. */

  #include <stdio.h>
  int numberOfSentences (void);
  int max, count;

 main()
 {
     int max = numberOfSentences();  //GAMBIARRA TO PUT MAX INTO THE ARRAY
     char *array[max];
     printf("The number of sentences is %d.\n", max);

     /*Getting sentences from the keyboard*/

     for (count = 0; count < max; count++) //Pay attention if the user
doesn't enter the number >ERROR
     {
         printf("Enter sentence # %d: ", count+1);
         array[count] = gets(*array);   //This line is working  BIZARRE 

         /*Print the sentences on screen*/

         printf("Sentence %d is %s\n", count+1, array[count]);
         system("pause");  //ONLY ACCEPTS A SENTENCE WITH AT MOST 10
CHARACTERS. OTHERWISE IT CLOSES.

     }

     system("pause");
     system("pause");
     return 0;
 }

/* Input number of sentences */

int numberOfSentences (void)
{
     printf("Enter the number of sentences: ");
     scanf("%d", &max);
     //printf("max = %d.", max);
     printf("\n");

     return max;
}
