幫我看看我寫ㄉC哪裡錯ㄌ

#include<stdio.h>
void main(void)
{
int i;
char a[74];
FILE *aa;
FILE *qq;
aa=fopen("my dir.txt","r");
qq=fopen("out.txt","w");
for(i=1;i<=73;i++)
{
fgets(a[i],73,aa);
fputs(a[i],qq);
}
}
12 C:\1.cpp passing `char' to argument 1 of `fgets(char *, int, FILE *)' lacks a cast
13 C:\1.cpp passing `char' to argument 1 of `fputs(const char *, FILE *)' lacks a cast

這是哪裡出ㄌ問題...可以幫我解答ㄇ
