Question

Modify your struct person to include an additional field to hold a last name. That should be declared as char lname[30]; //30 characters is probably long enough Modify your program so that in addition to reading ages and heights, it reads in a name for each person. At the end, in addition to printing the averages calculated previously, print the names of the oldest, youngest, tallest, and shortest people.

Answer 1

The answer to the question is explained below

Step-by-step explanation:

#include <stdlib.h>

#include <stdio.h>

#define MAXNUM 100

typedef struct person

{

int age;

double height;

}

person;

int getData(person people[], int max)

{

printf("Enter your age(or -1 to quit):");

int n = 0;

scanf("%d", &people[n].age);

while (people[n].age>0)

{

if(n == MAXNUM)

{

printf("You have reached the maximum limit");

return n;

}

printf("Enter your height:");

scanf("%lf", &people[n++].height);

printf("Enter your age(or -1 to quit):");

scanf("%d", &people[n].age);

}

return n;

}

void getAverages(person people[], double *averageAge, double * averageHeight, double *averageRatio, int numPeople)

{

*averageAge = 0;

*averageHeight = 0;

for(int i = 0; i <numPeople; i++)

{

*averageAge += people[i].age;

*averageHeight += people[i].height;

}

*averageAge /= numPeople;

*averageHeight /= numPeople;

*averageRatio = *averageAge / *averageHeight;

}

void printAverages(double averageAge, double averageHeight, double averageRatio)

{

int age;

double height;

printf("Result:\\");

printf("Average age is %.2lf\\", averageAge);

printf("Average height is %.2lf\\", averageHeight);

printf("The average age/height ratio is %.2lf\\", averageRatio);

}

void main(void)

{

person people[MAXNUM];

int numPeople;

double averageAge, averageHeight, averageRatio;

numPeople = getData(people, MAXNUM);

if (numPeople == 0);

getAverages(people, &averageAge, &averageHeight, &averageRatio, numPeople);

printAverages(averageAge, averageHeight, averageRatio);

}
