The 'while' loop can be implemented (in C) as: inti=5; while(i>=0) { printf("%d",i); i--; } where 'i' is the loop variable The 'do-while' loop can be implemented (in C) as: inti=5; do { printf("%d",i); i--; ...
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....
What would happen to the time complexity (Big-O) of the methods in an array implementation of a stack if the top of the stack were at position 0? Explain. Explain array in java. Explain the difference between while loop and for loop? Give an example for the while loop and the for lo...
Inside the heat exchanger, the water from the reactor gives up its energy to cooler water flowing in another closed loop, turning it into steam. Using two unconnected loops of water and the heat exchanger helps to keep water contaminated with radioactivity safely contained in one place and well...

Some of them are meant to be very strong and durable (car bits and prosthetic body parts are examples), while others are designed to fall apart in the environment relatively quickly (biodegradable plastic bags, for example). The properties of a plastic can also be deliberately engineered. ...
Explain also has a built in function library. Some of these functions are general purpose while others are designed for the needs of corrosion measurement. Some of the functions are very simple, while others have several parameters and are quite complex. ...
However, this protocol can cause a redirect loop in special circumstances. For example, if you’ve forced SSL on your site without installing an SSL certificate, you’ll likely see the error. That’s because all requests to your hosting server are sent over HTTP, which your server has to ...

You should be aware that while this makes the output easier to read, it also renders the JSON invalid, causing JSON functions to raise an error. See also Section 14.17, “JSON Functions”. Trying to use an INTO clause without explicitly including FORMAT=JSON causes EXPLAIN to be rejected...
