how to use find function with vector to find a pair of numberHello all
I am declaring a 2 dimensional vector like this vector <int> components(numodnodes); vector <int> coordinates(2,components(numofnodes)); as we know find function can be used with vector to find a particular value. like this if (find (marks.begin(), marks.end(), 0) == marks.end()) { // 0 is not found in the sequence } above marks was a one dimensional vector as in my defination , I have a 2 dimensional vector with number of rows =2, and number of columns = number of nodes. is ther any way that I can use this find function to find a pair,(like (2,4)) rather than a single number like this if (find (cordinates.begin(), marks.end(), (2,4)) == marks.end()) { // (2,4) is not found in the sequence } or what is the right method, to know if both numbers 2 and 4 are present at same column. that is (2,4) pair is present or not Thank you |
