title: Are the "usual arithmetic conversions" and the "integer promotions" the same thing?
body: <p>Are the "usual arithmetic conversions" and the "integer promotions" the same thing? I have read that the "usual arithmetic conversions" are used to make the operands of an expression the same type, while "integer promotions" are used to promote the types smaller than <code>int</code> to <code>int</code>, but in <a href="https://msdn.microsoft.com/en-us/library/3t4w2bkb.aspx" rel="nofollow">MSDN</a> both of these concepts are placed under "usual arithmetic conversions" only.</p>
