Does anyone know how to truly select random element from a vector v? I tried this: int rnd; rnd = v[ (int)floor( (double)rand()*( (double)v.size() / (double)RAND_MAX ) ) ]; cout<< "Random element: "<<rnd; But every time it's selecting only one particular element from my vector. It should be random right. …

Not stuck and no real question, which is unusual for me. Just a comment. The 2nd term in a for loop establishes the condition under which the loop terminates. For example, this loop terminates when i increments to 5... for(i=0; i<=5; i++) { ... ... } It'll execute its contents …
