Get Price2021-7-20 · C++ introduced a different cast system from C that distinguishes the types of cast operations. The problem with C casts is the ambiguity of the operation; sometimes you are doing a conversion (e.g., (int)3.5) and sometimes you are doing a cast (e.g., (int)'hello'). Brace initialization and C++ casts can often help avoid this ambiguity.
