File IO: You need to include the struct Person, createPerson, and printPerson from 2). (Code "2)" is at very bottom) a) Write a function that opens a file named test and prints some random text to the file. (not graded) b) Write a program that opens a file name test and prints the content of the file to screen. (not graded) III) Write a function void savePerson(char fileName[], Person p)that opens a file named fileName and prints the person to the file, as follows:

Name age score // Ex. Rickard 31 100

c) Write a function Person loadPerson(char fileName[]) that reads the file created by savePerson and returns a Person with the attributes in the file.

The function prototypes and a sample main are provided below:

Person createPerson(char name[],int age,double score); //from 2) void printPerson(Person p); //from 2) void savePerson(char fileName[], Person p); Person loadPerson(char fileName[]);

void hw5_3(){ Person p = createPerson("Rickard",31,100); char file[] = "testPerson"; savePerson(file,p); //check file manually Person p2 = loadPerson(file); printPerson(p2); };

CODE 2:

#include

#include

typedef struct

{

char name[20];

int age;

double score;

}Person;

Person createPerson(char name[],int age,double score);

void printPerson(Person p);

void changeAge(Person * p,int newAge);

void printPeople(Person people[],int length);

int main()

{

Person p = createPerson("Rickard",31,100);

printPerson(p);

changeAge(&p,30);

printPerson(p);

Person people[3];

people[0] = createPerson("John",22,83);

people[1] = createPerson("Donnie",24,63);

people[2] = createPerson("Marry",20,81);

printPeople(people,3);

return 0;

}

Person createPerson(char name[],int age,double score)

{

Person p;

strcpy(p.name,name);

p.age=age;

p.score=score;

return p;

}

void printPerson(Person p)

{

printf("Name :%s ",p.name);

printf("Age :%d ",p.age);

printf("Score :%.2lf ",p.score);

}

void changeAge(Person * p,int newAge)

{

p->age=newAge;

}

void printPeople(Person people[],int length)

{

int i;

for(i=0;i

{

printf("____ Person#%d ____ ",i+1);

printPerson(people[i]);

}

}
