Newbie problem

Hello, i''ve just started to learn C

this is my code:

Code:

---

#define MAX 100

char **text ;
 
int lines;

 
 
  printf("number of lines?\n");
  scanf("%d",&lines);

  text = (char**)malloc(linhas*sizeof(char*));
  int i=0;

  do{
      text[i] = (char*)malloc(MAX*sizeof(char));
      printf("%d) ",i+1);
        scanf("%(%d)[^\n]",MAX,text[i]);
      i++;
  }while(i<lines);

---

Thats the problem:
after the first loop iteration, it jumps to the end of loop. what am i doing wrong?

i'm using:
MinGW
Code::Blocks

Bad copy and paste here!


Real quick..where are your ';' to terminate the commands? Also there is no need for &word, just use the variable name as this is a pointer.

Some spelling problems seen as well.

Check your return value for your malloc call.

Do not forget to call free().

sorry, i fixed ;P

This is puzzling. What is your intent here

Code:

---

scanf("%(%d)[^\n]",MAX,text[i]);

---

Should you be using...

Code:

---

scanf("%s",text[i]);

---

The reason I say, that is because MAX is a constant and can not be assigned to.

i need to catch a string with spaces.

i tried
scanf("%100[\n]",texto[i]);
scanf("%100[]",texto[i]);
scanf("%100[^\n]",texto[i]);
scanf("%s100[^\n]",texto[i]);

with no success

scanf("%100[^\n]",texto[i]);

will work, but to make it dynamic you'll have to form the string FIRST: sprintf(control, "%%%i[^\n]", MAX);
Then you can scanf(control, texto[i]);

Probably, however, you should use fgets().

the better succes until now is when i used:

Code:

---

  do{
        texto[i] = (char*)malloc(MAX*sizeof(char));
        printf("%d) ",i+1);
        scanf("%*[^\n]",texto[i]);  // reads all caracter until '\n' appears.
        scanf("%*c");                    // reads '\n'
        i++;
    }while(i<linhas);

---

it skips the first input, although all other lines recieve it's inputs,

That should do the trick. Please keep in mind the dangers of using scanf! If your array is not large enough, scanf will write past it with no problem or a care in the world.

Code:

---

scanf("%[^\n]",text[i]);

I did it! :D

Code:

---

    do{
        texto[i] = (char*)malloc(MAX*sizeof(char));
        printf("%d) ",i+1);
        scanf("%*c");               
        scanf("%100[^\n]",texto[i]); 
        scanf("%*c");               
        i++;
    }while(i<linhas);

thank u all :)
