推荐答案

当你使用fgets（）时，你将使用换行符char作为分隔符从文件中提取字符串（字符数组）。 fscanf（）更适合从文件中提取内容。

When you use fgets(), you're pulling strings(character arrays) from the file with the newline char as the delimiter. fscanf() would be more appropriate for pulling ints from files.

程序打印50的原因是因为while循环后magicSquareArray [0]的值是'2 '，而不是2，'2'的ascii值是50。

The reason your program prints 50 is because the value of magicSquareArray[0] after the while loop is '2', not 2, and the ascii value of '2' is 50.
