Programming Definition and 1000 Threads

Hi fellas. Thanks for taking the time to read my post. I basically wanted to know if it is better to learn programming different languages rather than say building things? The reason I ask is because I want to get an internship by next year and I have no experience with programming or...

This might sounds stupid but I'm just curious, what is the best programming language we have today?

this is the program which i wrote: #include<iostream.h> #include<conio.h> #include<stdlib.h> void prime(int p) { if(p==0||p==1) { cout<<"neither prime nor composite"<<endl; getch(); exit(1); } for(int i=2;i<p/2;i++) { if(p%i==0) { cout<<"composite"<<endl; break; } else...

Hey guys, I am trying to create a 2d simulation of the Earth going around the sun. However I am facing an issue. I am not sure what are the forces that apply on the Earth in a 2d aspect. I know there is the gravitational pull GM1M2/R^2. I know there is momentum, which is P = V * R...
