For example, the size of a standard int is 4 bytes, whereas a char type is 2 bytes of length. When an arithmetic operation involves integer data types of unequal length, the compiler employs the policy of integer promotion.Integer Promotions...
intxm=x; // If n is in bytes, n << 3 will be the number of bits in that byte // For example, if n is 2 (as in 2 bytes), n << 3 will be 16 (as in 16 bits) xn=x>>(n<<3); // Mask off everything except the part we want xn=xn&0xFF; // Do the same for m...
For a program written in C (see Chapter 13), if you explicitly use a casting technique, you can safely convert one element size to another. The nature of data storage depends only on how many bytes are needed to represent a particular data storage element. An unsigned integer is usually ...
Recently, the good folks in the Windows division set out to create small set of C functions (obviously, you can use them in C++ code too) to perform safe integer arithmetic. These functions are used mainly to perform safe memory allocation calculations and array offset calculations. The small...

In C#, the double data type is a floating-point type that represents a double-precision 64-bit number (8 bytes). On the other hand, the int data type is an integer type representing a 32-bit signed integer. Converting a double to an integer in C# can be done using: ...
