INT32_MAX和INT32_MIN分别为int32_t的最大值和最小值。 注意:混用定宽整数类型和普通整数类型可能会影响跨平台编译,例如: cpp #include<cstdint>#include<iostream>intmain(){longlonga;int64_tb;std::cin >> a >> b;std::cout << std::max(a, b) << std::endl;return0;} ...
The storage of the vector is handled automatically, being expanded as needed. Vectors usually occupy more space than static arrays, because more memory is allocated to handle future growth. This way a vector does not need to reallocate each time an element is inserted, but only when the additi...

How to delete element from Vector: There is tricky thing for deleting in vector loop. The erase method returns the next element after the one you just erased. So you can use that to continue in your loop. vector c; iterator i = c.begin(); ...
