我想知道是否有可能,例如我int temp后来定义,我定义temp为float.
我的意思是我想在.cpp文件中多次使用名称"temp" .这可能吗?如果有可能,怎么样?
编辑:我的意思是在同一范围内.

不,您不能在同一范围内声明两个具有相同名称的变量.它们的范围必须不同.
像这样:
int temp; // this is global
struct A
{
int temp; // this is member variable, must be accessed through '.' operator
};
int f1()
{
int temp; //local temp, though the global one may by accessed as ::temp
...
}
int f2()
{
int temp; //local
// a new scope starts here
{
int temp; //local, hides the outer temp
...
}
// another new scope, no variable of the previous block is visible here
{
int temp; // another local, hides the outer temp
...
}
}
