Yes, the increase assignment operator (+=) should be avoided for building an object collection, see also: PowerShell scripting performance considerations. Apart from the fact that using the += operator usually requires more statements (because of the array initialization = @()) and it encourages to store the whole collection in memory rather then push it intermediately … Read more
it’s XOR operator (exclusive OR op.): will toggle (invert) the bit of an operand in position where any bit having value 1 in the other operand int ans = a[i]^1; e.g. a 4 byte size, at an i: a[i] = 00000000 0000000 1000000 1000001 1 = 00000000 0000000 0000000 0000001 ———————————- XOR 00000000 0000000 1000000 … Read more
The results are different because the lauguages are specified differently. why java says 50 Because the order of evaluation is defined so in Java. The addition is: 6+7+8+9+10+10 == 50. The final post increment is overwritten by the assignment and has no effect. while c++ says 51 The shown program has undefined behaviour in C++, … Read more
One will compile, one won’t. this is a pointer, and you can’t apply . to a pointer. Use -> to access members of the object it points to.
I suppose it should be while (rndNumber == 1as1 || rndNumber == 1as2) After || operator you need to specify full boolean expresion, there is not shorthand for right argument only.
You ask for a number, but you are trying to compare it to non-numeric data. Forget language semantics, how do you expect to compare a number to text? What does it mean to ask if a number like 3 is equal to “higher”? The answer is that it is nonsensical; this is one reason why … Read more
expression ? value 1 : value 2 if expression is true, result is value 1 (first condition) if expression is false ,result is value 2（second condition） Example: x = 1, x > 10 ? x : 10 expression: x > 10 => false value 1: x value 2: 10 result is 10
You probably meant to write a * (a//b). Multiplication happens before division, since it’s on the left and has same priority.
