The parameters of the two-parameter form of the main function allow arbitrary multibyte character strings to be passed from the execution environment (these are typically known as command line arguments). The pointers argv[1] .. argv[argc-1] point at the first characters in each of these stri...
按地址传递(Passing by reference)是一个使函数返回多个值的有效方法。例如,下面是一个函数,它可以返回第一个输入参数的前一个和后一个数值。// more than one returning value include <iostream.h> void prevnext (int x, int& prev, int& next){ ...
