Repeat a sound/action every certain time
python,date,time,while-loop,repeat
Your logic is wrong. First of all, the while loop will most likely end in the first iteration and you want the program to continue till you tell it to. In addition to that, you don't update the now variable inside the loop, which is basically a bad idea. For...
How to write my program without loops

Copy A to B and then multiply the elements not divisible by k by k: A=[1 2;3,4]; k=2; A1=A/k; B=A; B(A1-fix(A1)~=0)=B(A1-fix(A1)~=0)*k; Edit: Also without using an extra array, similar to eventHandler's idea: B=A; B(mod(A,k)~=0)=B(mod(A,k)~=0)*k ...
(JS) Why is my While Loop not working!? Perhaps I don't understand the basic concept
Am I right here: n is a variable, with value 4. while n = 4, print "Hey" in console. while(n) doesn't check to see if n is 4, it checks to see if n is truthy*. Both 4 and 5 are truthy values. To check if it's 4, use...
How many times are primitive data types allocated inside loops?
c++,while-loop,allocation,variable-declaration,value-initialization
Logically, yes, the variables are being created at the start of the loop body for every iteration of the loop, and destroyed at the end. In your first example, the constructor of std::string (actually std::basic_string<char> which is what std::string is) will be invoked for every iteration, as will the destructor....

while loop is not breaking even if the condition is satisfied
