What you need to know:One.1.if statementsThe C language provides a syntax format called an IF statement, and the general form is:if (Express){Programming statements;}With this syntactic sentence, you can start execution of one or more program

Fast sorting because of the efficiency of the sorting efficiency in the same O (N*logn) of several sorting methods, so often adopted, coupled with the rapid sequencing of ideas----division of the method is also practical, so many software companies

I wrote this automatic generation of pupils arithmetic code is based on the Baidu I saw a blog change, the address is http://www.cnblogs.com/ys1101/p/4368103.html. Its function is not complete, only the whole number of add, subtract, multiply,

1: Take a[4][3] for exampleA represents the address of a two-dimensional array, with pointer operators to get the elements in the array(1) A+n represents the first address of the nth line(2) &a[0][0] can be considered as the first address of the No.

1, choose the idea of sorting is: Iterate the array, the first time to find out the minimum value of all members, placed in the array subscript 0 position, the second time from the remaining content, again find the minimum value, placed in the array
