如何修改特定地址的值

[u010576908]

#include<stdio.h>
#include<string.h>
int main()
{
char *c="im the best";
char *fynd=strstr(c,"b");
printf("%s\n",c);
*fynd='6';
printf("%s\n",c);
printf("%s\n",fynd);

return 0;
}

我的目的是将c串中的"im the best"改为"im the 6est"，但F9后就会弹出程序崩溃的框，这是为什么呢

字符串常量的类型是const char *,你用char *很容易出错. 于是改成:

char c[]="im the best";

字符串常量不可 修改

修改如下：

#include<stdio.h>
#include<string.h>
int main()
{
	//char *c = "im the best";    //c指向一常量，不可对常量修改
	char c[] = "im the best";     //等价于 c[12]={'i','m',' ','t','h','e',' ','b','e','s','t','\0'};
	char *fynd = strstr(c, "b");
	printf("%s\n", c);
	*fynd = '6';
	printf("%s\n", c);
	printf("%s\n", fynd);

	return 0;
}
//im the best
//im the 6est
//6best
