Question

A weather analysis program uses the following array to store the temperature for each hour of the day on each day of a week. int temp [7] [ 24 ] ; Each row represents a day \((0=\text { Sunday, } 1=\text { Monday, etc. })\) and each column represents a time \((0=\text { midnight }, 1=1 \text { a.m., } \ldots, 12=\text { noon, } 13=1 \text { p.m., etc. })\) A) Write code to find Tuesday's average temperature. B) Write code to find the average weekly noon temperature.

Short answer

Answer: The process involves the following steps: 1. Calculate the sum of temperatures for Tuesday by iterating through row index 2 of the 2D array and adding the values. 2. Divide the sum of Tuesday temperatures by the total number of hours (24) to get the average temperature for Tuesday. 3. Calculate the sum of noon temperatures over the week by iterating through column index 12 of the 2D array and adding the values. 4. Divide the sum of noon temperatures by the total number of days (7) to get the average weekly noon temperature.

Step-by-step solution

Calculate the sum of temperatures on Tuesday

To find the average temperature for Tuesday, we first need to loop through the temperatures stored in row index 2 of the temp array representing Tuesday. We will calculate the sum of these temperatures. ```c++ int sum = 0; for (int i = 0; i < 24; i++) { sum += temp[2][i]; } ```

Calculate the average temperature for Tuesday

To calculate the average temperature, divide the sum of temperatures by the total number of hours (24). ```c++ double averageTuesdayTemp = sum / 24.0; ``` Now `averageTuesdayTemp` contains the average temperature of Tuesday.

Calculate the sum of noon temperatures over the week

To find the average weekly noon temperature, we first need to loop through the temperatures stored in column index 12 of the temp array representing noon. We will calculate the sum of these temperatures. ```c++ sum = 0; for (int i = 0; i < 7; i++) { sum += temp[i][12]; } ```

Calculate the average weekly noon temperature

To calculate the average noon temperature, divide the sum of temperatures by the total number of days (7). ```c++ double averageWeeklyNoonTemp = sum / 7.0; ``` Now `averageWeeklyNoonTemp` contains the average weekly noon temperature.
