 #include<stdio.h>//外掛printf() fprintf() fscanf() fopen()

int main(int argc,char**argv)

{

    FILE * fout=NULL;//檔案指標file output變數

    fout=fopen("a.txt","w+");//開啟檔案a.txt 模式write+

    printf("Hello World\n");

    fprintf(fout,"Hello World\n");//改裝printf變成fprintf

}

備份的程式碼 以後需要

#include <stdio.h> ///step01 外掛 printf(), fprintf(), fscanf(), fopen()

int main( int argc, char** argv )

{

///    FILE * fout=NULL;///step01 檔案指標 file output 變數

///    fout = fopen("檔名.txt", "w+");///step01 開啟檔案,檔名.txt, 模式write

///

///    printf("Hello World\n");

///    fprintf(fout, "Hello World\n");///step01 改裝 printf() 變 fprintf()

///先把舊程式 註解 掉

    FILE * fin = NULL;///step03 改成讀檔

    fin = fopen("檔名.txt", "r"); ///step03 開啟step01/step02的檔案,Read

  ///scanf(  "%d", &n ); //int n

  ///scanf(  "%c", &c ); //char c

  ///scanf(  "%f", &f ); //float f

  ///scanf(  "%s", line ); //char line[100];

    char line[100]; ///step03 宣告一個字串 line

    fscanf(fin, "%s", line); ///step03 讀入一個字串

     printf("現在讀到的是 %s \n", line );///step03 順便印出字串

    fscanf(fin, "%s", line); ///step03 讀入一個字串

     printf("現在讀到的是 %s \n", line );///step03 順便印出字串
