vector and pairs

This is a discussion on vector and pairs within the C++ Programming forums, part of the General Programming Boards category; Code: for(i=1;i<=m;i++) { cin>>u>>v>>c; G[u].push_back(pair<int,int>(v,c) ); } i just started with it... my scenario is user gives another two i/p ...

    vector and pairs

    Code:
    for(i=1;i<=m;i++)
        {
                         cin>>u>>v>>c;
         G[u].push_back(pair<int,int>(v,c) );
    
    
    }
    i just started with it...
    my scenario is user gives another two i/p say a ,b

    i have to check wat are all adjacent to a and reach b sumtime ..(at the end return sums of c in the path).. how do i do it using vector and pairs....

    a sample code or extension of this code would be helpful

    Write more clearly in English and elaborate on what you are trying to do.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
