下面的代碼在編譯，運行時沒有問題，在輸入內容是出現異常如下：
0x0F19B7EC (ucrtbased.dll)處(位於 ex6.exe 中)引發的異常: 0xC0000005: 寫入位置 0x00740000 時發生訪問沖突。
#include "stdafx.h"
#include <conio.h>
#include <stdio.h>
int main()
{
int NUM, I;
struct STUDENT
{
char NAME[30];
int AGE;
char ID[10];
};
struct STUDENT STD[100];
_cprintf("\nHow many student do you have ? Input the nuber;");
scanf_s("%d", &NUM);
for (I = 1; I <= NUM; I++)
{
_cprintf("\nInput student %d -- name:", I);
scanf_s("%s", &STD[I - 1].NAME);
_cprintf("\nInput student %d -- age:", I);
scanf_s("%d", &STD[I - 1].AGE);
_cprintf("\nInput student %d -- ID:", I);
scanf_s("%s", &STD[I - 1].ID);
}
_cprintf("\nTo see the RESULT,Press Any Key... ...");
_getch();
for (I = 1; I <= NUM; I++)
{
printf("\n student %d -- name: %s", I, STD[I - 1].NAME);
printf("\n student %d -- age: %d", I, STD[I - 1].AGE);
printf("\n student %d -- ID: %s", I, STD[I - 1].ID);
}
_cprintf("\nPress Any Key To EXIT... ...");
_getch();
return 0;
}
解決方法：
將上面的紅色標記代碼修改如下：
// ex6.cpp: 定義控制台應用程序的入口點。
//
#include "stdafx.h"
#include <conio.h>
#include <stdio.h>
int main()
{
int NUM, I;
struct STUDENT
{
char NAME[30];
int AGE;
char ID[10];
};
struct STUDENT STD[100];
_cprintf("\nHow many student do you have ? Input the nuber;");
scanf_s("%d", &NUM);
for (I = 1; I <= NUM; I++)
{
_cprintf("\nInput student %d -- name:", I);
scanf_s("%s", &STD[I - 1].NAME,30);
_cprintf("\nInput student %d -- age:", I);
scanf_s("%d", &STD[I - 1].AGE);
_cprintf("\nInput student %d -- ID:", I);
scanf_s("%s", &STD[I - 1].ID,10);
}
_cprintf("\nTo see the RESULT,Press Any Key... ...");
_getch();
for (I = 1; I <= NUM; I++)
{
printf("\n student %d -- name: %s", I, STD[I - 1].NAME);
printf("\n student %d -- age: %d", I, STD[I - 1].AGE);
printf("\n student %d -- ID: %s", I, STD[I - 1].ID);
}
_cprintf("\nPress Any Key To EXIT... ...");
_getch();
return 0;
}
