Thanks var Numbers =… Read More C# -> 7 in a string, convert to int returns 55?
As far as I understand .NET concepts, the source code is first translated into an Assembly (IL code+meta data), which is compiled to machine code on the target machine with the CLR’s JIT compiler. However I cannot really match these concepts to what I see when working on a C# project. When I build a… Read More Understanding .NET compilation
I’m making a program to add items to a LIFO (last in first out) array, where the elements are inserted at the start of the array. Here is my code: typedef struct neud{ int num; struct neud *next; }neud; void add(neud** head,int val){ //creat a new neod neud* newNeod; newNeod = malloc(sizeof(neud)); //assigning newNeod->num =… Read More I'm having a problem understanding double pointers

Hi I’ve been learning ReactJs and I wrote these lines: handlerClick(i) { this.setState( (state) => (state.squares = […state.squares, (state.squares[i] = "X")]) ); } Now, I know whats happening but I’m confused with how this is working, the order that each operation is being executed… >Solution : Regarding the order of operations, everything to the right… Read More Can someone explain how this state update is resolved?
So, I have a single byte in bytes format looking something like that: b’\xFF’ It is quite easy to understand that a single byte is the two symbols(0-F) after ‘\x’ But sometimes the pattern doesn’t match, containing more than two symbols after ‘\x’. So, for example, if I use secrets.token_bytes() I can get something like… Read More What are these symbols in 'bytes' type?
My question is on Python pandas. Suppose we have pandas dataframe df with two columns "A" and "B". I subset to select all values of column "B" where the entries of column "A" are equal to "value". Why does the order of the following commands not matter? df[df["A"]=="value"]["B"] Returns the same as the code df["B"][df["A"]=="value"]… Read More Subsetting Pandas dataframe based on Boolean condition – why doesn't order matter?
