我的代碼:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define CHAR_BUF 128
#define DATA_FILE "database.txt"
typedef struct client
{
char fname[CHAR_BUF];
char lname[CHAR_BUF];
int pnumber;
float wins;
float loses;
float ratio;
}client;
int ReadData(FILE *fp);
int main()
{
//int lines=0;
//client client[i];
FILE *fp = fopen(DATA_FILE, "r"); // opens file
if(fp==NULL) // checks if .txt file is empty
{
printf("Database is empty.");
exit(1);
}
ReadData(fp); // Calls function to read db
//lines = ReadData(fp);
//printf("Line amount: %d", lines);
}
/* This function reads data from database
* and assigns values to their variables
*/
int ReadData(FILE *fp)
{
int i=0;
client client[i];
while(!feof(fp))
{
fscanf(fp, "%s %s %d %f %f", client[i].fname, client[i].lname,
&client[i].pnumber, &client[i].wins, &client[i].loses);
printf("%s %s %d %.2f %.2f\n", client[i].fname, client[i].lname,
client[i].pnumber, client[i].wins, client[i].loses);
i++;
}
return i;
}
使用正確的工具來解決這些問題是你的調試器。在*堆棧溢出問題之前,您應該逐行執行您的代碼。如需更多幫助,請閱讀[如何調試小程序(由Eric Lippert撰寫)](https://ericlippert.com/2014/03/05/how-to-debug-small-programs/)。至少,您應該\編輯您的問題,以包含一個[最小,完整和可驗證](http://stackoverflow.com/help/mcve)示例,該示例再現了您的問題,以及您在調試器。 –
