I was attempting to highlight only the areas I wanted to draw attention to. The areas where I felt the coding issue might be. This time I have placed comment above all the functions stating what my expectation is of that function and the problem I am having. I will place the whole code in the tags.

Making the changes you suggested worked. Thank you. I am still having a problem with the table format output. The program reads the last line and saves it. Each time the program opens and reads the line again it is not appending to the original file. The original line is overwritten. I tried to open the file using the append method with no success. The questionable areas are highlighted below.

I've changed the function data type to float. When the user exits the program they should use -1. How do I ensure they are still using -1 rather than -1 0 0 0 or -1.0? The revised code is noted below.

float processCharge(float shippingWeight)
{   
    
    const int size = 50;
    float shippingCost;
    int weight[size] = {1,2,3,5,7,10,13,16,20,25,30,35,40,45,50};
    float cost [size] = {1.50,2.10,4.00,6.75,9.90,14.95,19.40,24.20,27.30,31.90,38.50,43.50,44.80,47.40,55.20};
    
    for(int index = 0; index < size; index++)
    {
            if (shippingWeight <=weight[size])
            {
               shippingCost = cost[size];
            }
    }
    return shippingCost;

)

My array wants to return a float shippingWeight. I am receiving an error message that I am converting an integer to a float. I am attempting to compare the weight value passed to the function to the weight value in the weight array. Once I find a value close to the weight passed it should assign the value in cost array to shippingWeight. Cost array is a float as well, I have not identified where the float integer conversion error in the code. My revised code looks like this:

int processCharge(int shippingWeight)
{   
    
    const int size = 50;
    float shippingCost;
    int weight[size] = {1,2,3,5,7,10,13,16,20,25,30,35,40,45,50};
    float cost [size] = {1.50,2.10,4.00,6.75,9.90,14.95,19.40,24.20,27.30,31.90,38.50,43.50,44.80,47.40,55.20};
    
    for(int index = 0; index < size; index++)
    {
            if (shippingWeight <=weight[size])
            {
               shippingCost = cost[size];
            }
    }
    return shippingCost;

I apologize no2pencil. I've place my code in tags except on the first post. I am not sure why it isn't taking. Used both methods you mentioned. I am kind of new navigating the site and posting. Thank you for your assistance.
