在Go 语言中,可以使用unsafe.Sizeof()函数来获取变量或类型的大小(以字节为单位)。下面是一个示例代码,演示如何使用unsafe.Sizeof()函数: package main import ( "fmt" "unsafe" ) type Person struct { Name string Age int } func main() {
golang sizeof 占用空间大小 C语言中,可以使用sizeof()计算变量或类型占用的内存大小。在Go语言中,也提供了类似的功能, 不过只能查看变量占用空间大小。具体使用举例如下。 package mainimport("fmt""unsafe") type Manstruct{ NamestringAgeint}funcmain(){...
varn int16 fmt.Printf("n变量占用的字节数:%d \n",unsafe.Sizeof(n)) n变量占用的字节数:2 bit是计算机最小存储单位;byte是计算机基本存储单元 使用类型时,按照变量具体使用,合理设置类型,不要设置太大的类型造成内存空间浪费 在go语言中,int和int16是不同的数据类型,以此类推 ...
