fscanf的用法

import core.stdc.stdio;
extern(C):
void main()
{
    //char[20]b="aa.txt";
    FILE*f=fopen("aa.txt","r");
    char[30]a;
    fscanf(f,"%s",a.ptr);
    printf("%s",a.ptr);
}
//fgets用法
import core.stdc.stdio;
extern(C):
void main()
{
    char[30] b;
    FILE*f=fopen("aa.txt","r");
    char*t=fgets(b.ptr,30,f);
    //printf("%s",b.ptr);//也可以
    printf("%s",t);//返回缓冲区地址
}
