As low-level programming languages, the designs of C and C++ closely follow what common hardware is capable of. The primitive building blocks (fundamental types) correspond to entities that common CPUs natively support. CPUs typically can handle bytes and words very efficiently; C called these char and int. (More precisely, C defined int in such a … Read more
It’s not completely clear what you are looking for, but note that java long arithmetic is effectively done mod 264. You can investigate modular inverses and the extended euclidean algorithm yourself, as well as how java handles integer overflow. The BigInteger class makes doing these experiments relatively easily, as this example shows. public class Main … Read more
The program has following issues: Array indexing is wrong : Array is of size 5 starting from 0 , you can use only till a[4] , but for scanf() , it tries to read value as &a[5]. No use of for loop when you are using hard coded index a[1],a[2],etc. Instead the below code will … Read more
The solution was to add a p in the URL in the Retrofit answer before (id) (what they call URL manipulation, check out the Retrofit site to find out more about that) where the id long was given. Thanks for the help ideas though! solved NumberFormatException, Invalid long
var X = 0 This is the line that declares X’s type, regardless of how it’s later used. When you specify a numerical literal without any suffixes, it will be an integer. Here’s one possible solution. var X = 0L solved C# – var not behaving as expected in for loop
What you want to accomplish is called de-serialisation or de-marshalling. For values that wide, using a loop is a good idea, unless you really need the max. speed and your compiler does not vectorise loops: uint8_t array[6]; … uint64_t value = 0; uint8_t *p = array; for ( int i = (sizeof(array) – 1) * … Read more
Here is a way you could achieve your purpose. int num = 2; // for example int out = 1; for (int exp = 1; exp <= 10; exp++) { out *= num; printf(“%d\n”, out); } Remarks about your code: Your inner while loop is infinite if num and expnt are both different from 0. … Read more
