Explain the difference between while loop and for loop? Give an example for the while loop and the for loop. Write the following code #pragma warning(disable: 4996) int getNum(void) { /* the array is 121 bytes in size; we'll see in a later lecture how we can improve this code *...
In most of the programming languages, three looping structures 'for', 'while', and 'do-while' are used to perform the statements that need to be executed repetitively until a given condition is satisfied. For example, the 'for' loop can be implemented (in C) as: ...
While declaration multiple variables and providing multiple arguments in a function, comma works as a separator. Example: int a,b,c; In this statement,comma is a separator and tells to the compiler that these (a, b, and c) are three different variables. ...
The following code provides an example of a nested loop join. BEGIN; CREATE TABLE public.nestedloop_test_1 ( a integer not null, b integer not null ); CALL set_table_property('public.nestedloop_test_1', 'distribution_key', 'a'); CREATE TABLE public.nestedloop_test_2 ( c integer not...
Artwork: How pulleys work#1: With one wheel, a pulley simply reverses the direction of the force you apply. It doesn't alter the force in any other way. Two wheels Now if you add more wheels, and loop the rope around them, you can reduce the effort you need to lift the weight. Su...
