• Confusing If Statement?

  - by NetSide

  I always use If statement (In C#) as (1. Alternative); if (IsSuccessed == true) { // } I know that there is no need to write "== true" as (2. Alternative)); if (IsSuccessed) { // } But, I use it because it is more readable and cause no performance issue. Of course, this is my choice and I know many software developers prefer first alternative. What is the best usage, and Why?

• Any pitfalls using char* instead of void* when writing cross platform code?

  - by UberMongoose

  Is there any pitfalls when using char*'s to write cross platform code that does memory access? I'm working on a play memory allocator to better understand how to debug memmory issues. I have come to believe char*'s are preferable because of the ability to do pointer arithmetic and derefernce them over void*'s, is that true? Do the following assumptions always hold true on different common platforms? sizeof(char) == 1 sizeof(char*) == sizeof(void*) sizeof(char*) == sizeof(size_t)

• finding if an anniversary is coming up in n days in MySql

  - by user151841

  I have a table with anniversary dates. I want a query that returns me rows of anniversaries coming up in the next 10 days. For instance: birthdate --------- 1965-10-10 1982-05-25 SELECT birthdate FROM Anniversaries WHERE mystical_magical_mumbo_jumbo <= 10 +------------+ | birthdate | +------------+ | 1982-05-25 | +------------+ 1 row in set (0.01 sec) I'd like to keep the query in the form x <= 10, because I'll use that number 10 in other parts of the query, and if I set it to a variable, I can change it once everywhere by changing the variable, and not have to re-write the query.

I'd like to write a function that uses templates, which in turn calls another function based on the type passed: template <class T> void test_function (T var) { //Do stuff if (T == char) { bar (var); } else { foo (var); } //Do even more stuff } If not, I'll have to fallback to enums...
