Trying to go through a 2d array, and not getting the correct values?
java,if-statement,multidimensional-array,int,paint
The first index in a 2D array is by convention the row index and the second is the column index, so your co-ordinates are the wrong way round: public void collisionChecker(int playerX, int playerY){ //takes the user's location and then checks if they are running into the wall if(mazeWalls[playerY /...
Converting a integer to char by adding '0' - what is happening?
Each symbol has an numeric representation, so basically each char is a number. Here is the table of characters and its values. So, in your code name[1] = numbers[1];, you assign name[1] to 2, which is equal to symbol STX in the ASCII table above, which is not a printable...
Dynamic Array Size in C++
You cannot create an array with run-time size, it must be known at compile time. I would recommend a std::vector instead. One solution would be to count the characters after converting to a string #include <string> int MyFunction(int number) { std::vector<int> myarr(std::to_string(number).size()); } Mathematically, you can take the log (base...
Calculating time for any sum to double, at a given rate of interest compounded annually
interest is an int so this line interest / 100 is doing integer division, and will always be 0. The quick fix would be to change the literal so you are doing floating point math sum += sum*(interest / 100.0); ...

The htonl function is declared in <arpa/inet.h>. Assuming you have a proper #include for that header: #include <arpa/inet.h>` the declaration uint32_t htonl(uint32_t hostlong); will be visible, so the compiler knows the expected argument type and the result type. If you want to pass the value 5 to the htonl function,...
Printing Int variable in Float format [duplicate]
c,gcc,int,printf,format-specifiers

C++ string.length() Strange Behavior
This is because .length() (and .size()) return size_t, which is an unsigned int. You think you get a negative number, when in fact it underflows back to the maximum value for size_t (On my machine, this is 18446744073709551615). This means your for loop will loop through all the possible values...

Java method returns double | int
I'm not quire sure I understand the intention of returning a double or and int knowing that's not really possible for a single function to return different data types. What I think I understand from your sample code, is that if a String (For example, "123.0" doesn't matter how many...
Is it possible to differentiate between 0 and -0?
It depends on the machine you're targeting. On a machine that uses a 2's complement representation for integers there's no difference at bit-level between 0 and -0 (they have the same representation) If your machine used one's complement, you definitely could 0000 0000 -> signed 0 1111 1111 -> signed...
Objective C unsigned char to negative int
Converting the unsigned char to a signed char first, then going to an int will give you the result you want: unsigned char x = 0xEC; char x1 = (char)x; int x2 = x1; As CRD points out, the C specification leaves the fact that char could either be signed...

How do char and int work in C++
char is a fundamental data type, of size 1 byte (not necessarily 8bits!!!), capable of representing at least the ASCII code range of all characters. So, for example, char x = 'a'; really stores the ASCII value of 'a', in this case 97. However, the ostream operators are overloaded so...
Typecasting int pointer to float pointer
c,pointers,floating-point,int,type-conversion

Last two bits in a BitArray of length 4 are being ignored when converting to int
The constructor for BitArray(bool[]) accepts the values in index order - and then CopyTo uses them in the traditional significance (so bitArray[0] is the least significant bit) - so your true, true, false, false ends up meaning 0011 in binary, not 1100. It's not ignoring the last two bits -...

You are treating m1 as a nested list of integers: result[i][j] += m1[i][k] * m2[k][j] # ^^^^^^^^ It is not; it is merely a simple list of integers. m1[i] then is an integer object and you cannot index integers: >>> [3, 4, 2][0] 3 >>> [3, 4, 2][0][0] Traceback (most...
How does C treat char sums?
From the C Standard, 6.3.1.8 Usual arithmetic conversions, emphasis mine: Many operators that expect operands of arithmetic type cause conversions and yield result types in a similar way. The purpose is to determine a common real type for the operands and result. For the specified operands, each operand is converted,...
C/C++ How to convert back int to string (a word)?
The challenge is to realize you have a string of hex and a string of decimal, meaning you have a character string representation of the values, not the values themselves. So you will need to convert the string representations to the appropriate numeric values before converting back to the original...
Swift - generate random Integer between 0.1 and 0.6
Okay here is the working code - thanks to @mireke for help // delay before playing var lower : UInt32 = 1 var upper : UInt32 = 6 var delayTime = arc4random_uniform(upper - lower) + lower var delayTimer = Double(delayTime) / 10 var delay = delayTimer * Double(NSEC_PER_SEC) var time...
