c - 用 fgetc 读取某些字符

Question

我正在尝试创建一个拼写检查程序，该程序接受输入文件并通过搜索字典文件来确保每个单词都是正确的。我面临的问题是，当我尝试从输入文件中取出由空格分隔的每个单词并将其放入char []单词中时，"出于某种原因打印

H0
i1
c0
h1
r2
i3
s4
!5
â0
1
2
h3
o4
w5
w6
â7
8
9
a0
r1
42
e3
y0

    char norm[33];

    if ( argc < 3 ) /* argc should be 3 for correct execution*/

    }
    fclose( fdict );
    fclose( input );
