英文:
Is it valid for function parameter's names to be the same as the variables used in the call to the function?
问题
在程序中，可以使用与函数参数名称相同的变量名来调用函数，这是程序上没有问题的。例如：
int num1 = 10;
int num2 = 10;
int result = add(num1, num2);
但是，为了提高代码的可读性和可维护性，通常建议使用不同的变量名来调用函数，以避免混淆。这样可以更清晰地表达变量的用途和含义。例如：
int input1 = 10;
int input2 = 10;
int sum = add(input1, input2);
英文:
Say I have a function:
int add(int num1, int num2) {
num1 += num2;
return num1;
}
is it programatically correct to call the function with variable(s) which contain the same name(s) as the function's parameter's names?
example:
int num1 = 10;
int num2 = 10;
int result = add(num1, num2)
Or is it programatically correct to use different names for the function call's variables/function parameters.

是的。这些变量位于不同的作用域中，因此是完全有效的。请参阅名称查找和作用域：
英文:
Yes. Those variables are in different scopes, therefore it is perfectly valid. See Name lookup and Scope:
> Each name that appears in a C++ program is only valid in some possibly
> discontiguous portion of the source code called its scope.
