排错-Error--memory violation Exception ACCESS_VIOLATION received解决方

简介: 排错-Error--memory violation Exception ACCESS_VIOLATION received解决方

Error -- memory violation : Exception ACCESS_VIOLATION received

 


测试代码:

Action()

{

   char *a = NULL;

   strcpy(a, "shouke");

   return 0;

}

 

运行报错:

Action.c(4): Error: C interpreter run time error: Action.c (4):  Error -- memory violation : Exception ACCESS_VIOLATION received.

Action.c(4): Notify: CCI trace: Action.c(4): strcpy(0x00000000, 0x032b0111 "shouke")

.

Action.c(4): Notify: CCI trace: Compiled_code(0): Action()

 

原因分析:

char *a = NULL; a为指向栈内存的指针,暂时值为NULL,指向内存为空。所以,不能用于存放内容。

 

改正方法:

法一,用数组开辟栈内存

Action()

{

   #char *a = NULL;

   char a[20]={0};

   strcpy(a, "shouke");

   return 0;

}

 

法二,开辟堆内存:

Action()

{

   char *a = NULL;

   a = (char *)malloc(sizeof(char)*20);

   strcpy(a, "shouke");

   free(a);

   a = NULL;

   return 0;

}
