我正在尝试打印出包含控制台中某些元素的表格。我有一个macbook pro，用linux mint分区。在linux中，这完美地运行，一切都正确打印。
然而，在macOs中，我没有得到预期的结果。我将链接底部的源代码。 源代码是用linux编写的，但我只是使用标准的C语言。
这是我得到的。
我很擅长使用linux并在两个不同的操作系统之间进行编译。有什么我在这里可以忽略的。

FREELY - Data is added to table and user
handles indexing
1. Options - COLORFUL : make table sensitive to color and higlighting
RAINBOW : print table in rainbow colors, this will
automatically turn on colors as well
2. Alignment - CENTER, LEFT, RIGHT
example:
int options[3] = {STRICT, COLORFUL, CENTER};
--create new table

答案 0 :(得分：4)
var宽线220不是init :(
请将其初始化为零或其他
int wide; //<------- DECLARATION
int check_size;
/*Get overall table width, add together biggest
strings from all rows*/
for(i = 0; i < table -> col_dimension; i++) {
wide += width_arr[i] + 4; //<----------- USE
}
/*On top of this, add */
wide += table -> col_dimension - 2; //<----------- USE
printf("+");
ms(wide,'-'); //<----------- USE
printf("+\n");
您已申报但未初始化
你在Linux上很幸运，因为广泛等于0但不是在Mac OS中
