A research institute specializing in physiology is conducting a study on the strain and effects ofcommuting trips done on a bicycle or walking. When the physiological strain of commuting trips hasbeen studied, the results will be used in exercise prescriptions, which can then use commuting as partof an exercise regimen.In this program you will write a C++ program to analyze a small subset of the data that has beencollected.INPUT: Redirect the input from the file HR.txt.The file consists of three columns, with six lines of data for each person. The first line stores eachpersons ID number (integer), clinically measured maximum heart rate (integer), and age (integer).The following five lines contain the days average commuting heart rate, maximum commuting heartrate, and exercise heart rate for five consecutive working days. Then, the six line sequence is repeatedfor the next person. At times the heart rate monitors reacted to nearby power lines or other objects,and gave false readings. These incorrect measurements were rejected and show up in the data file as-1. On the days the person did not exercise, the exercise heart rate value is zero.PROCESSING: Use precisely six parallel arrays: one for subject numbers and five for the calculatedvalues as described below. Look at data for subject 4545 as this is discussed:

4545 190 52114.8 130 113.1102.6 131 0.0117.4 129 149.1-1 -1 114.0114.1 123 119.5 Using this information, calculate1. Average of the average commuting heart rates for each person.

For subject 4545 this would be (114.8 + 102.6 + 117.4 + 114.1)/4 since there was a daythat no reading was available. 2. Number of days that the person exercised on his/her own. For subject 4545 this is 4 since one of the days is 0. 3. Estimated maximum heart rate = 220 age.

For subject 4545 this is 220 52 = 168 4. Ratio (%) of measured maximum heart rate to estimated maximum heart rate.The maximum heart rate for each person has been measured during a maximumoxygen uptake test in the laboratory. During the test, the person exercised withincreasing intensity until exhaustion, and then the maximum heart rate was measuredclose to the end of the test. Using this measured maximum heart rate and the estimatedmaximum heart rate, calculate the percentage of the measured maximum heart ratewith respect to the estimated maximum heart rate. Note that this percentage canexceed 100%. For subject 4545, 190/168 * 100 = 113.1%

5. Ratio (%) of highest commuting heart rate to measured maximum heart rate. Find the highestmaximum commuting heart rate for a person, and then calculate the percentage of this valuewith respect to the measured maximum heart rate.

For subject 4545, 131/ 190 = 69.4%

OUTPUT: Output should be in the following format and sorted by subject number from low to high: COMMUTING AND EXERCISE HEART RATE SUMMARYSUBJECT AVERAGE DAYS ESTIMATED %MEASURED %MAXNUMBER COMMUTING EXERCISED MAX HR TO COMMUTING HR ESTIMATED HR TO MAX HR MEASURED XXXX XXX.X X XXX XXX.X XXX.XSAMPLE: COMMUTING AND EXERCISE HEART RATE SUMMARYSUBJECT AVERAGE DAYS ESTIMATED %MEASURED %MAXNUMBER COMMUTING EXERCISED MAX HR TO COMMUTING HR ESTIMATED HR TO MAX HR MEASURED 1124 112.5 4 184 96.7 81.5

The data the professor wants us to use is HR.txt

Can you please write the code without using global variables, she does not allow global variables at all.
