Abstract
C language module design is implemented mainly through the function. The information between the functions is delivered by parameters. The parameter delivery of the function includes the delivery value and delivery address. In order to distinguish the difference of the two modes, two methods of examples and illustrations are adopted. The instances which takes variable, array name and pointer as parameters are listed. By comparing the variation of formal parameter and actual parameter after function call, two laws of the parameter delivery, while the function was called, were summed up: the base type variable, array element and structure variables as parameters are passed by value, that is, they deliver information in one ways the array name and pointer as parameters are passed by address, that is, they share the same address.关键词
