我的程序似乎总是产生荒谬的错误。请给我指路。以下代码段剪切了所有不相关的部分。谢谢。
代码段A部分似乎无法正确初始化数组,如何调试?代码段的 B 部分总是崩溃,我错过了什么吗?
typedef unsigned long T_PSIZE;
int main()
{
int AG_TOTAL = 6 ;
/* part A1 */
T_PSIZE* cntPeopleByAge = new T_PSIZE[AG_TOTAL + 1];
/* part A2 - originally i use static array like this, but it also fails */
//T_PSIZE cntPeopleByAge T_PSIZE[AG_TOTAL + 1];
for (int i = 0; i < (AG_TOTAL + 1); i++)
{
std::cout << i << ":" << cntPeopleByAge[i] << "\t";
cntPeopleByAge[i] = 0;
std::cout << cntPeopleByAge[i] << "\n";
}
std::cout << "cntPeopleByAge:" << cntPeopleByAge[ AG_TOTAL + 1 ] << "\n";
/* part B */
delete [] cntPeopleByAge;
return 0; // <--- crash here!
}
