Question

*/Take help from question 2 plz dont do it question 2 once you have done.Using easy code process for easy to understand./*

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

4. Write a function that will find all the devices from a specific country and print the information using the function mentioned in the Question 2. Use the prototype - void countryWisePhone( SmartPhoneType mobileList[], int size, char *country);

5. write a function that will delete all the information of a specific smart phone from the file. Use the function prototype – void deletePhone(SmartPhoneType mobileList[], int size, int phoneID);

Answer 1

void deletePhone(SmartPhoneType mobileList[], int size, int phoneID)

{

int iIndexPos=-1;

int iLoop=0;

//locates the phone rec with the specified id

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

{

if (mobileList[iLoop].phoneID == phoneID)

{

iIndexPos=iLoop; //found it!!!

break;

}

}

if (iIndexPos>-1) //it is there

{

//moves each phone rec one position to the left, clobbering the target record

for (iLoop=iIndexPos; iLoop<size-1; iLoop++)

{

memcpy(&mobileList[iLoop],&mobileList[iLoop+1],SMART_PHONE_SIZE);

}

memset(&mobileList[size-1],0,SMART_PHONE_SIZE); //invalidates the last record

}

size--;

/* NEXT, you have to write this array containing size-1 records to the file, whose name is

neither specified, nor passed */

}
