错误：无法将类型“ double *”的值分配给类型“ double”的实体

Question

I encountered a problem while i type my code.

...
double* FindMax(const double* const arr, int n)
{
    double max;
    ...
    return &max;
}

int main()
{
    ...
    maxVal = FindMax(value, numbers);
    ...
}

When I call the function FindMax, the program error and not allow me pass the value to function FindMax. How can I make it possible, thanks a lot!

Answer 1

Two things, if maxVal is double, you cannot assign value of &max . It should be double * .
Secondly, never return address of local variable. Because once you return from function, local variable die.
