Using fgets with struct

Question

我得到以下错误建议:

注意:预期为'char *'，但参数类型为'int *'_CRTIMP __cdecl __MINGW_NOTHROW char * fgets (char *， int, FILE *);

这与t->名称等有关，我猜，有什么办法可以解决这个问题吗?

现在输赢的存储方式也很奇怪，程序是这样工作的:

inputs:
Name of team > goo
Wins of team > 3
Losses of team > 4
Name of team > goo
Wins of team > 4
Losses of team > 3
outputs
team 1 name is goo
team 2 name is goo

我的代码

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_SIZE 20
#define MAXC 1024
typedef struct {
char name[MAX_SIZE];
char wins[MAX_SIZE];
char losses[MAX_SIZE];
} teams;

int addteam(teams *t);

int addteam(teams *t) {
char buffer[MAXC];

printf("Name of team > ");
fgets(t->name, MAXC, stdin);
printf("Wins of team > ");
getchar();
fgets(t->wins, MAXC, stdin);
printf("Losses of team > ");
getchar();
fgets(t->losses, MAXC, stdin);
return 0;
}

int main() {
int numOfTeams;
char array[MAX_SIZE];
char * Ptr;
teams team[MAX_SIZE] = {{ .name = "", .wins = 0, .losses = 0}}; 
for(int i=0; i < 2; i++) {
addteam( &team[i] );
}
for(int j=0; j<2; j++) {
printf("team %d name is %s   %s    %sn",j+1, team[j].name, team[j].wins, team[j].losses);
}
}

fgets将文本行读入字符缓冲区。fgets对数字一无所知。

代替

fgets(t->wins, MAXC, stdin);

char buffer[100];  // temporary buffer for line containing a number
fgets(buffer, sizeof(buffer), stdin);  // read line
t->wins = atoi(buffer);                // extract number

对t->losses做同样的处理。您可能应该将其放在int ReadIntFromLine(FILE *input)之类的函数中。

免责声明:

我们可以使用strtol来代替atoi，这对于现实世界的程序来说是一个更好的选择，因为它允许检测格式错误的输入。
