Does the following segment of code have any memory violations?

1: bookArr[i].authors = (author_t* ) calloc(bookArr[i].numAuthors, sizeof(author_t)) 2: for (int j = 0; j < bookArr[i].numAuthors; j++) { 3: bookArr[i].authors[j].name = (char *) calloc(80 + 1, sizeof(char)); 4: scanf("%s", bookArr[i].authors[j].name) 5: scanf("%d", &bookArr[i].authors[j].birthYear); 6: scanf("%d", &bookArr[i].authors[j].publishings) 7: }
