確定一個字符串在規定的字符串中的行列位置

#include <stdio.h>
#include <string.h>

int main(void)
{
	char *str[] = {"Hello world","Hello hell","hello aka","hello hello hoho"};
    char src[32] = {0};
	char *tmp = NULL;
	int  i;
	int len = sizeof(str)/sizeof(str[0]);
	while(1)
	{
		printf("Enter a string:\n");
		scanf("%s",src);
		if(!strcasecmp(src,"exit"))
            return 0;
        for(i = 0; i < len; i++)
		{
			tmp = str[i];
            while((tmp = strstr(tmp,src)) != NULL)
			{
				printf("%s :row = %d col = %d\n",src,i,strlen(str[i]) - strlen(tmp));
				tmp += strlen(src);
			}
		}
	}
	return 0;
