[C/C++基礎]- strstr:字串搜尋，strcat:合併，strcpy拷貝

本篇要分享-純C語言strstr:字串搜尋，strcat:合併，strcpy拷貝_實作，有興趣的(C/P)同好，歡迎來(C/P)一下哈哈 ^ ^。

#include <stdio.h> #include <stdlib.h> #include <string.h> char gchrOutput[1024]; void m3u8_strstr() {     char chrm3u8[]=".m3u8";     char chrColon[]="://";     char chrData[1024];     char *p='\0';     char *p1='\0';     p=strstr(gchrOutput,chrm3u8);     printf("point=%d\n",(p-gchrOutput));       printf("gchrOutput before=%s\n",gchrOutput);       if((p-gchrOutput)>0)     {         p1=strstr(gchrOutput,chrColon);         strcat(chrData,"http");         strcat(chrData,p1);         printf("Data=%s\n",chrData);           strcpy(gchrOutput,chrData);       }       printf("gchrOutput after=%s\n",gchrOutput); } int main() {     printf("Hello world!\n");     strcpy(gchrOutput,"rtsp://127.0.0.1/123.m3u8");     m3u8_strstr();     strcpy(gchrOutput,"rtsp://127.0.0.1/123.wmv");     m3u8_strstr();     return 0; }
