Check if entire vector is zero
c++, vector
Solution
It depends on what you mean by looping, but this would work:
bool zeros = std::all_of(v.begin(), v.end(), [](int i) { return i==0; });
Problem
How could I check if every single element in a vector is zero without looping through them? Current I have (In semi-MEW form): What this attempts to do is check if all three values of the final vector (its three dimensional... year.) is all zeros, (At the origin), or if it equals any previous vector on all three values. ``` siteVisited = false; counter = 0; while (counter < (walkHist.back().size()-1)) { tdof = 1; while (tdof <= dimensions) { if (walkHist.back().back().at(tdof-1) == 0) { siteVisited = true; } else { siteVisited = false; break; } tdof++; } if (siteVisited) { goto visited; } tdof = 1; while (tdof <= dimensions) { if (walkHist.back().back().at(tdof-1) == walkHist.back().at(counter).at(tdof-1)) { siteVisited = true; } else { siteVisited = false; break; } tdof++; } if (siteVisited) { visited: ... } counter++; } ```
