好的,所以我有这段代码,我想存储整数数组 intwholef[x] 的值,并将这些值存储在数组 Wholelist[y] 中。唯一的问题是我设置它的方式是我取数组的前三个值并将它们存储在 intwholef[x] 中,然后 x 在下一行传递时正在重置。图形表示如下
这是存储在字符串数组中的文件内容
intwholef[0] = 1 3 10
intwholef[1] = 2 4 15
intwholef[2] = 3 6 8
intwholef[3] = 4 7 3
intwholef[4] = 5 9 12
现在我想要的是像这样存储的那些值。
wholelist[] = 1,3,10,2,4,15,3,6,8,4,7,3,5,9,12
并且可以访问
wholelist[2] * wholelist[5] = 150;
我遇到的问题是我无法将值保存在这样的列表中,有什么想法吗?
这是整个代码,我正在谈论的部分在底部
