下午好,对于一个学校项目,我必须输入并显示客户端30天(1个月)的运动记录,客户端是一个包含天数组的结构,当我初始化程序时我会初始化我的客户矢量:
//Struct
typedef struct{
char name[100];
int dayOfBirth;
int monthOfBirth;
int yearOfBirth;
char address[100];
int phone;
int iRSNumber;
float height;
float weight;
int exerMinutes[30];
}client;
client clients[100] = {};
//initialize struct of clients
for(int i=0; i<100; i++){
strcpy(clients[i].name, "NULL");
strcpy(clients[i].address, "NULL");
clients[i].height = 0.0;
clients[i].yearOfBirth = 0;
clients[i].monthOfBirth = 0;
clients[i].dayOfBirth = 0;
clients[i].iRSNumber = 0;
clients[i].weight = 0.0;
clients[i].phone = 0;
for(int j = 0; j<30; j++){
clients[i].exerMinutes[j] = 0;
}
}
显示报告的代码:
system("cls");
printf("\nSHOW MONTHLY REPORT\n");
for(int i=0;i<30;i++){
if((i+1)%2==0 && i!=0){
printf("day %2d: %3d min\n", i+1, Client->exerMinutes[i]);
}else{
printf("day %2d: %3d min\t\t", i+1, Client->exerMinutes[i]);
}
}
printf("\n\nPress Enter to continue");
system("pause >nul /nobreak");
但是,用于初始化月份数组的for()循环似乎不起作用,因为当我请求月份报告时,这是输出:
day 1: 100 min day 2: 0 min
day 3: 0 min day 4: 0 min
day 5: 0 min day 6: 0 min
day 7: 0 min day 8: 0 min
day 9: 0 min day 10: 0 min
day 11: 0 min day 12: 0 min
day 13: 0 min day 14: 0 min
day 15: 0 min day 16: 0 min
day 17: 0 min day 18: 0 min
day 19: 0 min day 20: 0 min
day 21: 0 min day 22: 0 min
day 23: 0 min day 24: 0 min
day 25: 10 min day 26: 3 min
day 27: 1999 min day 28: 1280070990 min
day 29: 0 min day 30: 0 min
感谢您提供的帮助和/或建议。

代码运行良好,即,“结构”中的所有变量均以零或正好初始化。我尝试了一些更改。
问题在于以下几行:
if((i+1)%2==0 && i!=0){
printf("day %2d: %3d min\n", i+1, Client->exerMinutes[i]);
}else{
printf("day %2d: %3d min\t\t", i+1, Client->exerMinutes[i]);
}
您已经使用了指针来构造“客户端”,但尚未初始化,这就是得到意外结果的原因。请记住,在此“客户”中,您使用了大写字母“ C”。希望这会有所帮助:)
