0023
0024     int i, j, sum, id, divisors[] = { 10, 1 };
0025

0030         for (j = 0; j < 2; j++)
0031         {
0032             sum *= id / divisors[j];
0033             id = id % divisors[j];
0034         }
0035         categoryCount[sum % NUM_CATEGORIES] += productList[i].numberInStock;
0036     }

0042             printf("Category %d has %d items\n", i, categoryCount[i]);
0043         }
0044     }
0045
0046     return 0;
0047 }

each line that has code needs to be defined, can someone help me

Answer 1

Line 0001 - importing standard I/O library

Line 0003 , Line 0004, Line 0005 - defining CONSTANT

Line 0001-0012 - defining structure ProductInfo with attributes: prodID as int, numberInStock as int, and unitPrice as double

Line 0014 - declaring main function

Line 0015 - 0020 - passing array productList to the structure.

Line 0022 - Initializing array

Line 0024 - defining variables i, j , sum, id as int type & array divisors also of int type.

Line 0026 -0036 - initializing for loop that will give id, sum of product and this sum & id passes to function categoryCount for total count.

Line 0038- 0044- for loop to find the total count of category

Line 0046 - Exit status of program.
