I have wireless RF (433mhz) transmitter which is sending out packets to the receiver using RadioHead library. If there is a converted input voltage value on A0 pin, the transmitter send 1. Otherwise it sends 0. Everything is working completely fine and I can see the correct values on the receiver side. The problem is ..

In C++ we have the nice compact way to iterate over a vector: for(auto& item: myVector) { … } Is there any compact form for the same, if I want to iterate over myVector but I need to skip the first N items? I found a lot of references for skipping only the first item. ..
Hello I am making this question because on the for loop "for (grade = 0; grade != -1; numbOfTests++)" or in the getGrade function there seems to be an error if you enter the integer "-1" in the cin input first. More so it gives the "timeout: the monitored command dumped core" error. What is ..
Recently, I have written a shape generator to generate triangle and rectangle in C++. In this program, the rectangle function works fine as it does not have spacing between ‘O’. However, for my triangle function, there is a spacing between ‘O’, no matter how I adjust, the spacing between ‘O’ could not be eliminated. For ..
Perfect Numbers in a range int main() { int n, limit, sum = 0; cout << "Enter a number "; cin >> n; cout << "Enter a limit "; cin >> limit; for (int n = 1; n < limit; n++) { // Why do we need to use sum=0 here, if I have used ..
Currently I’m working project which I have to provide an reccurence relation of a function. The thing is that the function is an iterative function and I did not manage to write its reccurence relation. In addition, I am not sure if such a thing is possible or not. Is there any way to write ..
I’m trying to merge two loop functions. I’m trying to include the two into one void(loop). The first loop I call for a few functions being constData(); and varData();. The second loop is for a button/switch. How would I go about doing so? I am using an Arduino and C/C++ //first loop——– void loop(){ if(mode!=lastMode) ..
I unfortunately have been tasked with writing unit tests for python running on windows. I do not have access to containers and must deal with interacting with windows itself. I am running Python 3.9 I am using pexpect.popen_spawn to spawn the child python script I am writing tests for and using the expect method to ..
The following Code Snippet does exactly what I want it to do if the SRV record is present, which is print out each server withing the SRV record. However, if the SRV record isn’t found (which is expected in some circumstances, I see the error. :: Execute a Nslookup for the internal SRV Record and ..
I am writing a simple code to reverse a string in C++. However, I am encountering some problems. I am using the string "abcd" as an example because it is simple. When I am printing out the reversed string the result comes out as "dabc" which I’m not sure why. I have tried separating the ..
