一个星期过去了     还没想出来

谢谢啦
#include<stdio.h>
int main()
{
FILE*FP=fopen("pppp","r");
}

执行 link.exe 时出错.

002.exe - 1 error(s), 0 warning(s)

这个错在哪里呢      

麻烦运行一下这个看有没有出错
#include<stdio.h>
int main()
{
    int i;
    char a[5]={'a','b','c','d','e'};
    fopen("pppp","a");
    for(i=0;i<5;i++)
    fput(a[i]，D：\\pppp.txt);
}

谢谢

已经在书上找到了问题的原因  谢谢
