C Program only first reading車牌

Question

所以我已經經歷了一個問題，我必須爲學校製作一個出租車程序，所以，我有一個案例，我需要給用戶一個選項來改變車輛的可用性，但爲此用戶需要給牌照才能繼續。正如我兩路車添加到結構，案例3，程序只接受車牌1是正確的......

void alterarDisponiblidadeTaxi (TAXIS taxis[], int qtd_taxis){ 
int i=0; 
char matr[10]; 
if(0>=qtd_taxis){ 
    printf("No data has given yet!\a\n"); 
    return; } 
printf("Insert the vehicle's plate:\n"); 
scanf("%s",matr); 

if (strcmp(matr,taxis[i].matricula) == 0){ 
    printf("License plate found with sucess!\n"); 
    return 0; 
} 
if (strcmp(matr,taxis[i].matricula) != 0){ 
     printf("License plate not found with sucess!\a\n"); 
     return 0; 
} 
} 

Answer 1

我想你忘了添加一個for循環。由於i=0，它只會檢查第一個車牌。

void alterarDisponiblidadeTaxi (TAXIS taxis[], int qtd_taxis){ 
    int i=0; 
    char matr[10]; 
    if(0>=qtd_taxis){ 
     printf("No data has given yet!\a\n"); 
     return; } 
    printf("Insert the vehicle's plate:\n"); 
    scanf("%s",matr); 

    for(int i=0; i<qtd_taxis; i++) { 
     if (strcmp(matr,taxis[i].matricula) == 0){ 
      printf("License plate found with sucess!\n"); 
      return 0; 
     } 
    } 

    printf("License plate not found with sucess!\a\n"); 
    return 0; 
}
