C ++中的访问冲突错误

这是一个程序，该程序生成一个随机的2维数组，并按对角线元素升序排列.我收到"Acess Violation"错误，无法理解why.here，这是我到目前为止的内容.这个家伙有什么线索吗?
Laba6.exe中0x011bbfed的未处理异常:0xC0000005:访问冲突读取位置0x00000061.

This is a program that generate a random 2 dimensinal array and sots its diagonal elements in ascending order. I get an "Acess Violation" error and cant understand why.here it is what i have so far. any clue on this one guys?
