Master the idea of minimum spanning tree algorithm 2, Content and design idea The State Grid Corporation of China wants to lay out an EHV transmission network across the country and connect all provincial capitals. In order to reduce costs and meet some hard requirements, the ...

Sequential storage structure and chain storage structure of linear table and their simple operation (mixed use of C and C + +)1, Preface:In the first computer experiment when learning data structure, the teacher asked us to realize the sequential storage structure and chain storage structure of linear table and their simple operation. It was pa ...

C + + exception handling (try catch) The program often encounters some errors, such as divisor 0, age negative, array subscript out of bounds, etc. if these errors can not be found and handled, they may lead to program crash. The C + + exception handling mechanism allows us to catch and handle these errors, and then we can let the program cont ...

Double pointer algorithm We have already used the double pointer algorithm in quick sort and merge sort. The first type: the first pointer points to sequence 1 and the second pointer points to sequence 2 The second type: two pointers point to the same sequence for(int i=0,j=0;i<n;i++){ while(j<i && check(i,j)) j++; // ...

Thank you! 0x01 manual memory management In actual C + + development, we may have problems such as sudden crash during program operation due to improper manual memo ...

Basic form: int cmp(const void *a ,const void *b); Analyze this basic form: The return value of the function is int The formal parameters are two const void *, which means that the two parameters are of const void * type, that is, a pointer. Const represents that the value of the memory unit pointed to by the pointer cannot be changed. Void ...

C + + programming and object model design Conversion function #include <iostream> class Fraction { public: Fraction(int num, int den = 1) : m_numerator(num), m_denominator(den) {} operator double() const { return ((double)m_numerator/m_denominator); } private: int m_numerator; // molecule int m_denominator; // denominat ...

Recently, I started to watch Effective C + +. In order to facilitate future review, I specially took notes. If I misunderstand the knowledge points in the book, please correct!!! In the previous article, we learned the high efficiency of reference passing, but this does not mean that value passing is useless. If you only want to use reference ...
