long long get_ms(void) { long long ms = 0; struct timespec s; clock_gettime(CLOCK_MONOTONIC, &s); ms = (long long)s.tv_sec*1000 + s.tv_nsec/1000000; return ms; } 这个代码的问题在于类型转换的写法。 代码本身已经意识到了32bit的数据类型不够表征毫秒的问题,于是首先对其进行了long long...
C++ is a strong-typed language. Many conversions, specially those that imply a different interpretation of the value, require an explicit conversion. We have already seen two notations for explicit type conversion: functional and c-like casting: The functionality of these explicit conversion operators...

In the C programming language – a positive integer value (int) can be assigned in an unsigned integer (unsigned int or uint) automatically (implicit type conversion). But in the Go language, this assignment will not happen.See the below examples (C language code & Go language code) ...
Now, an important property of unsigned integral types in C and C++ is that their values are always in the range [0, max], where max for unsigned int is UINT_MAX (it's defined in limits.h). If you assign a value that's not in that range, it is converted to that range. So, if...

language background, like perl. The terms we use in C++ for read operations is something like "the first read". Casting is a different concept and quite a subject in itself. Btw, if you take care not to read EOF by adding a whitespace like " " or "\n", everything works fine. #...

In the <stdlib.h> there are few interesting functions that could be used to convert data types: atof(charArray) will transform the array in style of C language into float. atoi(charArray) will transform the array of chars into the int. ...
