未處理的異常

-6

我在編譯在Visual Studio 2013編寫了一個程序，我得到這個錯誤：（（在0x5837FB53（msvcr120d.dll）在ConsoleApplication2.exe未處理的異常：0000005：訪問衝突讀取位置0x0000006D））未處理的異常

我該怎麼辦？

這裏是我的代碼：

#define _CRT_SECURE_NO_WARNINGS 
#include <stdio.h> 

int jabs(int th) 
{ 
    if (th < 0); { 
     th *= -1; 
    } 

    return th; 
} 

int main() 
{ 
    char depature[8][8] = { "08:00 am" ,"09:43 am","11:19 am","12:47 am", "02:00pm" ,"03:45 pm","07:00 pm","09:45 pm" }; 
    char arrival[8][8] = { "10:16 am", "11:52 am", "01:31 pm", "03:00 pm", "04:08 pm", "05:55 pm", "09:20 pm", "11:58 pm" }; 
    int dep[8] = { 800,943,1119,1247,1400,1545,1900,2145}; 
    int str1[2]; 
    int str2[2]; 
    char str3[10]; 
    int temp; 
    int index; 
    int a[10]; 

    int i; 
    int j=0; 
    int javab = 0; 
    int javabs; 
    printf("enter a time corresponding 24 hour"); 
    scanf("%s", &str3); 
    for (i = 0; i <= 4; i++) 
    { 
     if (str3[i] != ':'){ 
      str1[i] = str3[i] - '0'; 

     } 
     else 
     { 
      i++; 
      str2[j] = str3[i]-'0'; 
      i++; 
      str2[j+1] = str3[i] - '0'; 
      break; 
     } 


    } 
    str1[0] = str1[0] * 1000; 
    str1[1] = str1[1] * 100; 
    str2[0] = str2[0] * 10; 
    javab = str1[0] + str1[1] + str2[0] + str2[1]; 
    for (j = 0; j < 8; j++) 
     javabs = (javab - dep[j]); 
     a[j] = jabs(javabs); 
    temp = a[0]; 
    for (j = 1; j < 8; j++) 
    { 

     if (temp > a[j]) 
     { 
      temp = a[j]; 
     } 
    } 
    for (j = 0; j < 8; j++) 
    { 
     if (temp == a[j]) 
     { 
      index = j; 
      break; 
     } 

    } 
    printf("closest departure time is %s,arriva at %s \n",depature[j][7],arrival[j][7]); 
    return 0; 

}`enter code here`

看起來像一個假地址（'0x0000006D'）??? –

您尚未預留NUL終結符的空間。掃描'％s'時不要在變量名前使用'＆'。如果（th <0）;'應該是'if（th <0）' –

當'i> = 2'時不要訪問'str1 [i]'和'str2 [i]'。代碼'str1 [i] = str3 [i] - '0';'可以做那個超出範圍的訪問。 – MikeCAT

char depature[8][8] = { "08:00 am" ,"09:43 am","11:19 am","12:47 am", "02:00pm" ,"03:45 pm","07:00 pm","09:45 pm" }; 
char arrival[8][8] = { "10:16 am", "11:52 am", "01:31 pm", "03:00 pm", "04:08 pm", "05:55 pm", "09:20 pm", "11:58 pm" };

留下空間'\0'，你可能想利用他們來%s打印。兩者的大小應該是 -

char departure[8][9]= // initialization 
char arrival[8][9]= // initialization

也在於此 -

scanf("%s", &str3); 
      ^& is not needed ,remove &

簡單地寫 -

scanf("%9s",str3);

depature[j][7]和arrival[j][7]是爲指針無效，所以你不能把它們傳遞給%s在printf。

行

printf("closest departure time is %s,arriva at %s \n",depature[j][7],arrival[j][7]);

應該

printf("closest departure time is %s,arriva at %s \n",depature[j],arrival[j]);

這將釋放你得到分割故障。

注意，有more warnings：

prog.c: In function 'jabs': 
prog.c:6:16: warning: suggest braces around empty body in an 'if' statement [-Wempty-body] 
    if (th < 0); {
