C Language Reference Manual Reading Notes: preprocessing instructions #, #, variable parameters

. Macro definition is valid, but # There is no mark to be combined on the right (unless + is encountered, but this is not what we want ). To solve this problem, we should regard the formal parameter I as a special "null" Mark specially designed for # extension. In this way, the result of the temp () + x extension will be temp + X as we expected.You cannot splice tags to generate common character names.Similar to converting macro parameters to strings (see section 3.3.8), programmers can exploit

Summary of the top ten ranking algorithms for Go Language (next)

This is a creation in Article, where the information may have evolved or changed. Hill sort Hill sort basic idea: First take an integer less than n D1 as the first increment, dividing all the records of the file into D1 groups. All records that are multiples of the DL are placed in the same group. First, the direct insertion sort is performed within each group, and then the second increment D2 the D1 repeats the above groupings and sorts until the increment dt=1 (dt dt-l ... d2 d1), where all re

My friends, I recently stepped up writing some C # algorithms. Select sorting and insert the algorithm I have introduced. Now we are introducing the hill sorting feature. In the future, I will introduce other algorithms in sequence.Hill sorting is to segment the group for insertion sorting.If you want to improve your C # programming skills, we can discuss with each other.For example, the following program does not implement polymorphism.
