This may be a silly question, but could someone please provide a standard reference for C++11 and C11:
Is char default-promoted to int?
Here's a little background: Both C and C++ have notions of default argument promotion (C++11: 5.2.2/7; C11: 6.5.2.2/6). This entails that in the following call, the arguments are promoted:
void f(int, ...);
float a = 1; short int b = 2; char c = 'x';
f(0, a, b, c);
For the function call, a is converted to double and b is converted to int. But what happens to c? I have always been under the impression that char also gets promoted to int, but I cannot find the relevant statement in the standards.
