Zero Initialization of struct, C++

Say I have this struct...

Code:

---

struct SomeStruct
{
 int a;
 int b;
 int c;
 int d;
};

---

My simple tests indicate this...

Code:

---

int main()
{
 SomeStruct ss{0};
 ...

 return 0;
}

---

...is equivalent to this...

Code:

---

int main()
{
 SomeStruct ss = {0};
 ...

 return 0;
}

---

Is this kosher??? In my research I found reference to the 2nd, but not the first, i.e., ...

Code:

---

ss{0}

---

Although I do not believe either conforms to any particular dietary laws, I do believe that they are essentially equivalent in the given context. However, you should get a warning about missing initializers if you are using a reasonable warning level (i.e., with g++ at least -Wall -Wextra).

In modern C++, the best way to zero-init your POD struct is with empty braces and no equals sign.

Or better yet initialize the variables in the structure definition.

Code:

---

struct SomeStruct
{
 int a{};
 int b{};
 int c = 0;
 int d = 0;
};

Thanks John and Jim. Appreciate it. Working on something, and the issue came up. My C++ is old, so I need to update.
