我正在撰寫代碼來列印三個驅動程式的詳細資訊，但問題是程式正確地獲取了驅動程式 1 的輸入，但跳過了驅動程式 2 和 3 名稱的輸入，盡管提供了輸入，但它仍將其列印distance travelled為0.0.
#include<stdio.h>
struct data
{
char name;
int dlo;
char route;
float km;
}s1,s2,s3;
void details(struct data *d)
{
printf("Enter your name: ");
scanf(" %s",&d->name);
printf("Enter your driving license no: ");
scanf("%d",&d->dlo);
printf("Enter route taken: ");
scanf("%s",&d->route);
printf("Enter distance travelled: \n");
scanf("%.2f",&d->km);
}
void output(struct data *d)
{
printf("Driver name: %s\n", &d->name);
printf("Driving license no: %d \n", d->dlo);
printf("Route taken: %s\n", &d->route);
printf("Distance travelled: %.2f \n", d->km);
}
int main()
{
printf("\n--------------driver 1---------------\n");
details(&s1);
printf("\n");
output(&s1);
printf("\n--------------driver 2---------------\n");
details(&s2);
printf("\n");
output(&s2);
printf("\n--------------driver 3---------------\n");
details(&s3);
printf("\n");
output(&s3);
return 0;
}
輸出是這樣的：
--------------driver 1---------------
Enter your name: abhishek
Enter your driving licence no: 123
Enter route taken: abcd
Enter distance travelled:
123
Driver name: abhishek
Driving licence no: 123
Route taken: abcd
Distance travelled: 0.00
--------------driver 2---------------
Enter your name: Enter your driving licence no: 321
Enter route taken: efgh
Enter distance travelled:
45
Driver name: 123
Driving licence no: 321
Route taken: efgh
Distance travelled: 0.00
uj5u.com熱心網友回復：
問題是，我以前%.2f在scanf這導致了運行時錯誤從而通過改變scanf("%.2f",&d->km);到scanf("%f",&d->km);的錯誤解決了我也不得不使用陣列name，并route避免進一步的運行時錯誤。
我真的很感謝大家的建議。
