我在 Visual Studio 2013 中编写了一个程序,在编译期间出现此错误:((ConsoleApplication2.exe 中 0x5837FB53 (msvcr120d.dll) 处未处理的异常:0xC0000005:读取位置 0x0000006D 时发生访问冲突。))

我该怎么办?

这是我的代码:

#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`

最佳答案

depature[j][7]arrival[j][7] 作为指针无效,因此您不得将它们传递给 %s printf 中。

线

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

应该是

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

这将使您避免出现段错误。

请注意,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); {

scanf("%s", &str3);
