freopen("log.txt",stdout);这个函数是将标准输出保存到指定文件 只要加到输出前面就可以了 实际上要按规范的话 最后还要加一行 fclose(stdout);当然 你不关闭也可以。但是最好还是加上 include<stdio.h> main(){ freopen("log.txt",stdout);int a,b;scanf("%d",&a);b=a;printf("%d",b...
可以在命令行里面执行,利用输出转向,比如要把a.exe执行的结果输出到a.txt中,可以执行下面的命令:a.exe > a.txt
int Z[1024]; memcpy(Z,e,1024*sizeof(int));/*如果只是复制,这个更高效*/ fp1=fopen("探测器KK.txt","w+"); for (i=0;i<1024;i++) //输出到TXT文件 { fprintf(fp1,"%d",Z[i]); } fclose(fp1);//关闭流 return 0; } else { printf("错...

您好,茫茫人海之中,能为君排忧解难实属朕的荣幸,在下拙见,若有错误,还望见谅!。简单的来说:FILE *fp = fopen(“*.txt”, "w");fprintf(fp, "这里放置你需要输出到txt文件的字符流!",...);fclose(fp)非常感谢您的耐心观看,如有帮助请采纳,祝生活愉快!谢谢!
void main(){ FILE *fp,*fp1;char str[200];if((fp=fopen("new.txt","wt"))==NULL) /* 假设新旧文本文件分别是new.txt,old.txt */ { printf("cannot open file\n");return;} if((fp1=fopen("old.txt","rt"))==NULL){ printf("cannot open file\n");return;} while (fgets...
请问怎样在c中把处理后数据输出到txt或dat文件? 收藏 回复 210.77.13.* 快试试吧,可以对自己使用挽尊卡咯~ ◆ ◆ 我用了fwrite,但怎么导出后的都是乱码??谢谢各位 风雨破老鼠 强能力者 7 #include "stdio.h" main(){ FILE *fp; fp=fopen("xxxxx.dat",w); fputs("Hello!",fp); fclose(...
