    Help - Creating a Graph in C++

    Hey community, my name's Zach.

    I am currently trying to create a project that enables me to calculate the % chance of hitting a specific square on a graph, depending on the projectile used.

    ~The Problem~
    I can do most of it but, I do not necessarily know where to start when it comes to actually creating the graph to have points plotted on? Can anybody tell me or point me in the right direction on how to figure this out?


    I looked on the internet a lot but no tutorial is really showing me anything that I can understand and then translate into a program.

    Are you talking about a visual representation "plotted" on screen - in which case, you need to tell us which OS and compiler you're using.

    Or are you just looking for a data structure to store the results of targets and hits, say
    Code:
    int grid[10][10] = {
        { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
        { 0, 0, 1, 1, 1, 0, 0, 0, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 2, 0, 0 },
        { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },   
    };
    
    if ( grid[rand()%10][rand()%10] == 2 ) {
      printf("You hit my battleship!\n");
    }
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    As Salem asks - what is the problem you are having? Using actual graphics is the obstacle? Or is it that you cannot yet figure a way of representing it in the computer memory? You should post your code - you say you can do most of it - so where do you get stopped?
