a file has the contents below.. Each number represents the amount of money made

Question

a file has the contents below.. Each number represents the amount of money made each month. Each line represents a new year (12 months per line). Right now, the program will read the numbers below and tell the month and year with the highest sales. Modify the program underneath so it will AT THE END tell the month with the highest sales each year (Do not change the current printf at the bottom, just add another one ). Uses arrays.

Explanation / Answer

in your variable declarations add this code: double tempSum = 0.0; int highestMonth = 0; double highestMonthIncome = 0.0; after your for loops add this code: for(m = 0; m < 12; m++) { tempSum = 0.0; for(y = 0; y < 5; y++) { tempSum += sales[y][m]; } if(tempSum > highestMonthIncome) { highestMonthIncome = tempSum; highestMonth = m; } } after your printf statements add this one: printf("The Month with the Highest overall sales: Month %2d, %.2lf Dollars ", highestMonth, highestMonthIncome);
