Sorting 2d Array to Find Highest Number

Blixamarkham (24)
Hi there! I was wondering if someone would be so kind as to look at my code and tell me how I can fix my output! My goal is to get the corresponding name, and the sales amount, that are highest for each Quarter of the Year. This is all MY code I made from scratch. Pretty proud of it. Would love to hear some criticism on anything I could do to make it prettier. Thanks!

First initialize highestSalesFirst = 0; and take one variable say int highestIndex;
1
2
3
4
5
6
7
8
 
for (int k = 0; k < 3; k++)
{
	if( sales[k][0] > highestSalesFirst )
	{
		highestSalesFirst = sales[k][0];
                highestIndex = k;
	}

}
After this for loop you can print it like,
cout << name[highestIndex<<"had the..........."<<highestSalesFirst<<" for Qt1";

I have figured that part out. I cannot figure out why I have this huge number for my output.

I guess no one can help me.

You need to initialze all your highestSales... variables to 0:
1
2
3
4
5
 
	double highestSales = 0;
	double highestSalesFirst = 0;
	double highestSalesSecond = 0;
	double highestSalesThird = 0;
	double highestSalesFourth = 0;


Otherwise those variables contain random values that might very well be the greater than one of the sales values. It's only by accident that just 'quarter 2' comes out that way
