#INTEGER OVERFLOW MATHEMATICA CODE#

You need to assign the shifted value back to num using the assignment operator (num = num > 1). This also leads to the integer overflow error you're experiencing. An overflow causes an error while running the function. So thats why the value of num remains unchanged, causing an infinite loop when num is greater than 0. You forgot to assign the shifted value back to the num variable within the while loop. Since you're performing a bitwise AND operation with num and the result of the comparison, the value of (1 = 1) is 1, and you effectively perform num & 1 in each iteration of the loop. When this occurs, the value may wrap to become a very small or negative number. In C++, the result of a comparison operation is either 0 (false) or 1 (true). An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation.

The bitwise AND operator (&) has lower precedence than the equality operator (), so the expression is evaluated as (num & (1 1)).

#INTEGER OVERFLOW MATHEMATICA CODE#

In C++, the result of a comparison operation is either 0 (false) or 1 (true). The integer overflow in your code is caused by the comparison (num&1 1) within the if statement. The bitwise AND operator (&) has lower precedence than the equality operator (=), so the expression is evaluated as (num & (1 = 1)). Types can be specified for input arguments to a function. The type of each intermediate computation is determined from knowledge of the function and the type of its arguments. The integer overflow in your code is caused by the comparison (num&1 = 1)within the if statement. Type System The Wolfram System compiler uses a type system to generate its instructions.
