#include <stdio.h> #include <string.h> int main(int argc,char**argv){ char *token = argv[1]; FILE *fp = fopen("./test.txt","a+"); char buf[1024]; char *p; int s=-1,len=strlen(token),line=0,pos=-1; while(!feof(fp)){ fgets(buf,sizeof(buf),fp); line ++; p = buf; while(*p){ if(*p==token[0] && s==-1){ s = 0; }else if(*p==token[s+1]){ s ++; }else{ s = -1; } p++; if(s==len-1){ printf("(%d,%d)\n",line,p-buf-len+1); s=-1; } } s=-1; } }

代码很简单，功能也很单一，这里就不多废话了，大家直接看代码吧。
