Hi, I´ve had some problems completing a program that I´ve worked with for a while now. Basically, i need to read data from a textfile with 30 beers each containing 10 elements(each element is seperated by a comma). This data is supposed to be stored in a struct with maximum capacity of 100 items(beers). Can someone explain how you´re supposed to solve it?
Code:#include <stdio.h> #include <string.h> #include <stdlib.h> #include <locale.h> void start(void) { char *oneline, *tok; char envara[256]; char delim[] = ","; FILE *fp; int i; struct vara { int nummer; char namn[100]; float pris; float volym; char typ[100]; char stil[100]; char forpackning[20]; char land[20]; char producent[50]; float alkoholhalt; } items[100]; items[i].nummer = atoi(tok); items[i].pris = atof(tok); items[i].volym = atof(tok); items[i].alkoholhalt = atof(tok); strncpy(&items[i].namn, tok, strlen(tok)); strncpy(&items[i].typ, tok, strlen(tok)); strncpy(&items[i].stil, tok, strlen(tok)); strncpy(&items[i].forpackning, tok, strlen(tok)); strncpy(&items[i].land, tok, strlen(tok)); strncpy(&items[i].producent, tok, strlen(tok)); if ((fp = fopen("varor.csv", "r")) == NULL) { fprintf(stderr, "Filen varor.csv gick inte att öppna\n"); exit(-1); } for (i = 0; i < 100 && fgets(envara, 256, fp); i++) { envara[strlen(envara) - 1] = '0'; // Ta bort radslutstecknet printf("%s\n\n", envara); oneline = strdup(envara); tok = strtok(oneline, delim); while (tok != NULL) { printf("%s\n", tok); tok = strtok(NULL, delim); } } free(oneline); free(tok); fclose(fp); }
