🛸Week15 存檔 讀檔🛸
✨存檔
🔼用fopen() fprintf()寫檔案
🧷程式
#include <stdio.h>///外掛
int main(int argc,char ** argv)
{
FILE*fout=NULL;///file output 變數
fout=fopen("檔名.txt","w+");///開啟檔案 檔名.txt，模式:write
printf( "Hello World\n");///小黑視窗的文字
fprintf(fout,"Hello World\n");///檔名.txt中的文字
}
____________________________________________________
✨修改專案目錄
🔼打開.cbp
🔼修改程式碼後

🧷程式
#include <stdio.h>
int main(int argc,char ** argv)
{
FILE*fin=NULL;///讀檔
fin=fopen("file.txt","r");///開啟檔案(Read
char line[100];
fscanf(fin,"%s",line);
printf("Read %s \n",line);
fscanf(fin,"%s",line);
printf("Read %s \n",line);
