While file data with regex

I have problem on while file data on get only regular expession. I would get only the sorted data table.

My file:

Foods list test.
Check all foods:
1   123456   Food Name 1
2   123457   Food Name 2
3   123458   Food Name 3
4   123459   Food Name 4
5   123460   Food Name 5
blablabla blablabla
...
file foods done

ID\tCOD\t(SPACE)NAME

My code:

int id, cod;
char name[64];
FILE *file;
file = fopen("foods.txt", "r")
while(fscanf(file, "(\d+)\t(\d+)\t (.*)", &id, &cod, name) != EOF)
    printf("ID: %d - Code: %d - Name: %s\n", id, cod, nome);

Is not working as it should, why? You are entering an endless loop.

The scanf function does not accept regular expressions. It has its own syntax similar to printf.

Try this instead:

while(fscanf(file, "%d %d %s", &id, &cod, name) == 3)
