This question already has an answer here:

I have the following variables:

char* words[20];
char* tracks[20];

where they represent the number of tracks and words saved in a database on a SD card. My question is that, I would like the array of words and tracks to be of variable size and not static, that it is I don't want to specify the size of the array.
