将[mw_shl_code=c,true]fopen(path,"w");[/mw_shl_code]改为[mw_shl_code=c,true]fopen(path,"r");[/mw_shl_code]

[mw_shl_code=c,true]#include <stdio.h>
#include <stdlib.h>
int main()
{
    char *path=(char *)calloc(256,sizeof(char));
    gets(path);
    FILE *fp=fopen(path,"w");
    fgets(path,256,fp);
    puts(path);

我从不用那么复杂的方法去做文件操作！[mw_shl_code=c,true]#include <stdio.h>
int main()
{
    FILE *fp=fopen("1.txt","w");
    fprintf(fp,"你好，欢迎你来到C++的世界");
    fclose(fp);
    fp=fopen("1.txt","w");
    fprintf(fp,"hello");
    fclose(fp);
    return 0;
}
