Question

Hello, I am in a C PROGRAMMING class and need help finishing this code. I must finish case three and the last function call. The program is based off FILE I/O it creates a file called input.txt and can create a person, print the file, search for a person, or exit. I am stuck with search for a person. The function call and prototype must not change. The program runs and compiles correctly as is but is missing the earlier said function.

Thank you

#include <stdlib.h>
#include <unistd.h>

#include <stdbool.h>

void addPerson();
void printFile();
bool readFileRecord(char *name);

struct person{
char name[100];
char number[100];
char address[100];
};

int main(){

int choice;
char name[100];

printf("1. Add person to file 2. Print person file 3. Search for person 4. Exit ");
scanf(" %d",&choice); getchar();

while(choice!=4){

switch(choice){

case 1:

addPerson();
break;

case 2:

printFile();
break;

case 3:

//case three must search for a person in a file and tell if the person exists

break;

case 4:

break;

default:

printf("Enter a valid option! ");
break;

}

choice = 0;
printf("1. Add person to file 2. Print person file 3. Search for person 4. Exit ");
scanf("%d",&choice); getchar();

}

return 0;

}

void addPerson(){

struct person *p = malloc(sizeof(struct person));
FILE *fp;

printf("Enter value for name: ");
fgets(p->name,99,stdin);
printf("Enter value for phone: ");
fgets(p->number,99,stdin);
printf("Enter value for address: ");
fgets(p->address,99,stdin);

fp = fopen("input.txt","ab");

if(fp!=NULL){
fwrite(p,sizeof(struct person),1,fp);
fclose(fp);
}
}

void printFile(){

struct person *p = malloc(sizeof(struct person));

printf("%s",p->number);
printf("%s",p->address);
}

fclose(fp);

}

bool readFileRecord(char *name){

//this function must be completed
//if the search person exists in the file it must
