1. Assume an integer array of size 12 named arrSales stores the sales of a product for each month. For example, sales for January should be stored in 1^st
   position of the array, and February is stored in 2^nd
   position of the array and so on for the rest of the months.

iv) Assume an integer array of size 4 named arrQtrSales is defined. Calculate each quarter sales and store into the array arrQtrSales based on the below formula:

• Quarter 1 sales : Total Sales from January to March


• Quarter 2 sales : Total Sales from April to June


• Quarter 3 sales: Total Sales from July to September


• Quarter 3 sales: Total Sales from October to December.

v) Using for loop and arrQtrSales array, calculate increasing percentage for each quarter. Display the output as shown in the sample output below. Use below formula for your calculation:

Increasing Percentage for current quarter = (sales in current quarter – sales in previous quarter) / sales in previous quarter * 100

Sample output:

Quarter 1 : RM6000

Quarter 2: RM12400( Increasing : 106%)

Quarter 3: RM19000( Increasing : 53%)

Quarter 4: RM14500( Increasing : -23%)
