Inside the text file, the first number is number of albums, second is number of tracks associated with a single album, and the number infront of each track title is the character length of the title.
Right now I am having trouble scanning in the name of each individual title (without the number in front) into char **tracks; which is also part of an array of Structs
For example, info[0].tracks[0] should print out the string "Like an umbrella".
Example Text File:
1
17
16 Like an umbrella
...
15 Dynasty Warrior
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
struct album
{
int num_tracks;
char **tracks;
};
int main(int argc, char *argv[]){
int numbALBUMS=0, numbCharInTrack=0;
int i=0,j=0;
FILE *albums;
albums = fopen (argv[1], "r");
fscanf(albums, "%d", &numbALBUMS);
struct album *info = (struct album*)malloc(numbALBUMS * sizeof(struct album));
for(i=0;i<numbALBUMS;i++){
fscanf(albums, "%d", &info[i].num_tracks);
info[i].tracks = malloc(sizeof(char*) * info[i].num_tracks);
for(j=0;j<info[i].num_tracks;j++){
fscanf(albums, "%d", &numbCharInTrack);
info[i].tracks[j] = malloc(sizeof(char) * numbCharInTrack);
//NEED HELP HERE
}
}
fclose(albums);
return 0;
}
try this
fscanf(albums, "%d", &numbCharInTrack);
info[i].tracks[j] = malloc(sizeof(char) * (numbCharInTrack+1));//+1 for NUL, sizeof(char) is always 1(by standard)
fscanf(albums, " %[^\n]", info[i].tracks[j]);//Space to skip the previous space
