C + + can use the const to define constants, or define constants using define #, which has more advantages than the latter.1) const data constants have data types, and macro constants do not have data types. The compiler can perform type safety

Problem DescriptionThe output Yang Hui the first n rows of the triangle.InputEnter a number n (n OutputThe output Yang Hui the first n rows of the triangle. (Note that there is no extra space at the end of the line, the number is output in%3d format)

Problem DescriptionEnter an unsigned short integer k[hex.] and P[oct.], the high byte of K as the low byte of the result, and the high byte of p as the result of the high byte to form a new integer.InputK[hex.] and P[oct.]OutputThe operation gets

When const is used in conjunction with pointers, it is easy to confuse:1. Can the const limit the pointer to other memory?2. Is it forbidden to modify the contents of the block of memory it points to by this pointer? (PS: This is said to prohibit

Today, using Unicode as a string is a common sense, but it's still a headache for some programming languages with a long history. Without the support of a third-party library, C + + does not actually support Unicode effectively, even if it is UTF8. (

A namespace is a domain in which all type names in a domain must be unique, with different types grouped into hierarchical namespaces.The benefits of namespaces are: 1, avoid name collisions, 2, easy to find type names.such as:
