Printing prime numbers from 1 through 100

The following prime numbers are printed out by this C++ code: 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 73 79 83 89 97. However, I don't believe that is how my book would prefer it to be written.  It makes a reference to the square root of a number.  I thus tried switching my second loop to for (int j=2; jsqrt(i); j++), but it did not produce the desired outcome. How would I modify this code to make it the way my book desires it to be? int main () { ...READ MORE

Why should I use reference variables at all?

References themselves are unrelated to the issue. The issue is because C++ manages object lifetimes differently from run-time systems that employ garbage collectors, such as Java.  There is no standard built-in garbage collector in C++.  Both automatic (within local or global scope) and manual (explicitly allocated/deallocated in heap) object lifetimes are possible in  C++. A C++ reference is nothing more than an object's alias.  It has no knowledge of object lifespan (for the sake of efficiency).  The coder must give it some thought.  A reference bound to a temporary object is an exception; in this situation, the temporary object's lifespan is prolonged to include the lifetime of the bound reference. References play a crucial role in the fundamental ideas of C++, and they are required for 90% of jobs.  Otherwise, pointers must be used, which is typically far worse. You can use references, for instance, when you need to give an object as a function parameter by reference rather than by value: void f(A copyOfObj); ...READ MORE
