Sir, i'm getting compilation error. please help me to figure out my mistake

#1
#2

i have removed all compilation error

  1. s.insert(make_pair(dij_dist,ngr.first));
    there should be a braces or use make_pair function
    s.insert(make_pair({dij_dist,ngr.first}));

  2. void addedge(int u, int v, int w ) {
    m[x].push_back(make_pair(y,w));
    m[y].push_back(make_pair(x,w));

    }
    it should be x and y not u and v

  3. unordered_map(int ,int) dist ;
    here you should use angular brackets
    unordered_map<int ,int> dist ;

#6

you are missing one check
if((nodedist+ngr.second)<dist[ngr.first])
here you also have to check whether then ngr.first is processed befor or not
it should not be processed before

#7

sir, Then how will i update the dist[ngr.first] if i get “if((nodedist+ngr.second)<dist[ngr.first])” ?

#8

you can use visited map for that
but you have to check this condition also
