Question

Write a program that reads by asking the user the name of the file. After opening it, read it into the structure of array. The input file is in the format: firstName lastName age result (Contents of the input file) The Temp 0 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 Edward Newman 61 3 1 2 2 2 3 5 3 5 3 5 1 3 1 4 3 5 2 5 3 5 1 3 1 5 1 5 3 1 1 3 1 3 1 3 3 5 2 1 2 3 5 1 1 3 3 5 3 1 5 The program reads the result into the structure called TheResult. The constants and the structure to be used is given below: const int EXTROVERSION = 0; const int AGREEABLENESS = 1; const int CONSCIENTIOUSNESS = 2; const int NEUROTICISM = 3; const int OPEN_TO_EXPERIENCE = 4; const int NUM_QUESTIONS = 50; const int NUM_RESULT = 5; const int MAX_RESULT = 5; struct TheResult { string firstName; string lastName; int age; int answers[NUM_QUESTIONS]; // result double normalizedResult[NUM_RESULT]; }; The name of the input file is obtained from the user. The data is read into an array of structures. After reading the data from the input file into the array of TheResult structures, calculate each result’s normalized result scores using the formulas below where (n) is the numeric answer to question n. extroversion = 20+(1)–(6)+(11)-(16)+(21)-(26)+(31)-(36)+(41)-(46) • agreeableness = 14-(2)+(7)-(12)+(17)-(22)+(27)-(32)+(37)+(42)+(47) • conscientiousness = 14+(3)-(8)+(13)-(18)+(23)-(28)+(33)-(38)+(43)+(48) • neuroticism = 38-(4)+(9)-(14)+(19)-(24)-(29)-(34)-(39)-(44)-(49) • openness to experience = 8+(5)-(10)+(15)-(20)+(25)-(30)+(35)+(40)+(45)+(50) Calculate each result’s score then normalize it from a scale of 0 to 40 to a scale of 1 to 5. For example: normalizedResult[EXTROVERSION] = (extroversion + 10)/10; After scoring all results, sort the array of TheResult structures by last name, calculate the averages of each trait, and print the array and averages in a form of a table as shown in the image.
