In this code, we declare and initialize variables `a` and `b` with integer and string values respectively, and we declare and initialize a constant `pi` with a float value of 3.14. We then print the values of these variables and constants to the console using `fmt.Println()`. Functions...

说明该程序需要使用fmt包中的某些函数或者是元素,那fmt就是一个非常常用的包,实现了格式化IO的函数,比如fmt.Println输出到console。 func main() 1. 这是程序开始执行的函数,main函数是每个可执行的程序必须包含的,一般来说是启动后第一个执行的函数,如果有init则例外,因为init()函数会先于main开始执行。 当标识...
