unsigned

Following is the c# code: static void Main(string[] args) { uint y = 12; int x = -2; if (x > y) Console.WriteLine("x is greater"); else Console.WriteLine("y is greater"); } and this is c++ code: int _tmain(int argc, _TCHAR* argv[]) { unsigned int y = 12; int x = -2; if(x>y) printf("x is greater"); else printf("y is greater"); return 0; } Both are giving different result. Am I missing something basic? Any idea? C++ and C# are different languages. They have different rules for handling type promotion in the event of comparisons. In C++ and C, they're usually compared as if they were both

What is the proper way to initialize unsigned char* ? I am currently doing this: unsigned char* tempBuffer; tempBuffer = ""; Or should I be using memset(tempBuffer, 0, sizeof(tempBuffer)); ? The second method will leave you with a null pointer. Note that you aren't declaring any space for a buffer here, you're declaring a pointer to a buffer that must be created elsewhere. If you initialize it to "" , that will make the pointer point to a static buffer with exactly one byte—the null terminator. If you want a buffer you can write characters into later, use Fred's array suggestion or something

How can this be done using ALTER statements? Table definition: ALLITEMS (itemid int(10) unsigned, itemname varchar(50)) I am using the following code but it is throwing error: syntax incorrect .

Currently I read the unsigned int into a Long but while writing it back I never managed to write the exact number back in 4 bytes as unsigned int. The long has the correct value that I need to write back. (eg 3289763894 or 370500) I am unable to even read the write a number smaller then Integer.MAX_VALUE (eg 2997). I am using the following methods to write the value back public void writeUInt32 ( long uint32 , DataOutputStream stream
