Question

Consider the following structure definition and solve the following problems.

typedef struct { int phoneID;

// unique ID will start from 1 up to N.

char phoneName[50];

int price;

int ramMemory;

float cpuSpeed;

int gpuMemory;

char userName[50];

int userPhoneNo;

char userCountry[50];

} SmartPhoneType;

1. Write a program that will read 5 mobile’s information from the user and save it in a file named “mobileInfo.txt”.

2. Write a function that will print all the information of a specific smart phone. Use the prototype - void printPhoneInfo(SmartPhoneType phoneType);

Answer 1

void SmartPhone_Output(TSmartPhone p)

{

printf("-------------------------------\n");

printf(" phoneID = %d \n",p->phoneID);

printf(" phone name :>%s< \n ",p->phoneName);

printf(" price = %d \n",p->price);

printf(" memory = %d \n",p->ramMemory);

printf(" cpu speed = %6.2lf \n",p->cpuSpeed);

printf(" gpu memory = %d \n",p->gpuMemory);

printf(" username:>%s<\n",p->userName);

printf(" user phone # = %d \n",p->userPhoneNo);

printf(" user country :>%s< \n",p->userCountry);

}

void printPhoneInfo(SmartPhoneType phoneType)

{

SmartPhone_Output(&phoneType);

}

void My5Phones(TPhoneDB phoneDB)

{

int iLoop=0;

phoneDB->count=phoneDB->phoneSeqNum=5;

phoneDB->phones=(TSmartPhone)malloc(5*SMART_PHONE_SIZE);

for (iLoop=0; iLoop<5; iLoop++)

{

phoneDB->phones[iLoop].phoneID=(iLoop+1);

SmartPhone_Input(&phoneDB->phones[iLoop]);

SmartPhone_Output(&phoneDB->phones[iLoop]);

}

WritePhoneFile(phoneDB,"E:\\mobileInfo.txt");

}
