==> Learning to program can be tough--just ask anyone who's done it! Fortunately, a lot of problems happen over and over again--I've put together 8 of the most common problems that you'll run into as a new programmer. 1. Undeclared Variables int main(){ cin>>x; cout< "Huh? Why do I get an error?" Your compiler doesn't know what x means. You need to declare it as a variable. int main(){ int x; cin>>x; cout< 2. Uninitialized variables int count; while(count "Why doesn't my program enter the while loop?" In C++ variables are not initialized to zero. In the above snippet of code, count could be any value in the range of int. It might, for example, be 586, and in that situation the while loop's condition w...
Most of us know that our brain functions in a complex manner. The neurons in the brain communicate using electrical signals, and our brain has around 100 billion neurons and each communicates with millions of others. The information thus is traveled and transferred at the atomic level. We can view and maneuver the signals through implants and wiring inside the brain, but only to some extent. A team of medical researchers at Florida International University in Miami has found another way of mapping the brain signals more accurately than ever. They injected 20 billion nanoparticles into the brains of mice, with the idea of establishing a kind of direct wireless connection to neurons. These are the ‘Magnetoelectric Nanoparticles’ ( MENs) that sneak up towards the neural networks inside the brain. The nanoparticles possess special properties. They produce electric fields in the vicinity of the individual neurons, when triggered by the magnetic field ex...
