将两个字符串链接

#include

void fun(char string1[],char string2[],char string[])
{
	int i,j;
	for(i = 0;string1[i] != '\0';i++)
	{
		string[i]=string1[i];
	}
	for(j = 0;string2[j] != '\0';j++)
	{
		string[i+j]=string2[j];
	}
	string[i+j] = '\0';
}

int main ()

	void fun(char string1[],char string2[],char string[]);
	char s1[100];
	char s2[100];
	char s[100];
	printf("intput string1:");
	scanf("%s",s1);
	printf("intput string2:");
	scanf("%s",s2);
	fun(s1,s2,s);
	printf("\nThe new string:%s\n",s);
	return 0;
