You could use something like this. Just keep a count of how many variables you've parsed so you know how many actual valid entries are in the array. Also, change DELTA appropriately to whatever a reasonable step size is for the array. Fewer reallocs means less overhead.

Typed in Mail so not guaranteed to be totally bug free, but it should work I think.


#define DELTA 10

int count = 0;
int capacity = DELTA:
float *variables;

variables = (float *) malloc(sizeof(float) * capacity);


while (parsing) { if (count >= capacity) { capacity += DELTA; variables = (float *) realloc(variables, capacity); } }

Hi,
how can I add an element to an array of float?
I am parsing a text file contains variables, but until I parse the whole
text I cannot know how many variables that text contains.
Actually I parse the text twice. The first time I count the variables then


    float   *variables = malloc(sizeof(float) * totVar);

then I parse the text again to put the variables into my array.
Is a way to do everything in one loop only? Will be faster?
Sorry for the silly question.
