Pointers are important concepts in the C + + language and are an important feature of the C + + language. With pointers, you can make your programs more concise, compact, and efficient.The memory of the computer hardware system has a large number of

A few years ago, Charles Simonyi (who later became Microsoft's famous programmer) devised a prefix-based naming method, which was later called the "Hungarian notation" to remember him. His idea was to give it a suffix based on what each identifier

C ++ (1): Data Type, Data TypeA computer processes data, and data exists in a specific form (such as integers, floating-point numbers, and characters ). There are often some relationships between different data (for example, an integer array

Variable naming rules ------ Hungarian naming rules! A few years ago, Charles Simonyi (who later became a well-known programmer at Microsoft) designed a post-fix-based naming method known as "Hungary notation" to remember him. his idea is to give

It seems that from the age of C, pointer has become a difficult point in the minds of the masses. In today's c ++, the complexity of object-oriented, template, and other technologies has reduced the difficulty of learning the basic process-oriented
