This may be due to a corruption of the heap, which indicates a bug in helloC++.exe or any of the DLLs it has loaded. This may also be due to the user pressing F12 while helloC++.exe has focus. The output window may have more diagnostic information. helloC++.exe是我的專題名，我有爬文只知道heap好像是一種記憶體的方式但是還是不太知道為什麼它會爆可以請板上的高手解答一下嗎小弟還是VC新手所以請板上高手盡量告訴感謝^^ Unhandled exception at 0x002718f7 in helloC++.exe: 0xC0000005: Access violation writing location 0x00160004. 有時後又會出現這種，真的是很頭痛 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.113.122.235 ※ 編輯: gw119 來自: 140.113.122.235 (04/30 20:50)
