Question

PLEASE HELP ME GUYS ! THIS IS VERY IMPORTANT
This is my airline reservation prog. that was modified by someone else.That person introduced files in the program to create and display simple profile info. for passengers and their booked flights.(which is my goal)
Now he used stuff such as "itoa" AND "outfile.open(str.c_str()); " (character casting),
"memset", dynamic arrays etc. PLZ CAN ANY OF U SEE WHETHER THE PROGRAM BELOW CAN BE DONE IN AN EASIER WAY (IM A NEWBIE TO FILES AND NOT SUCH AN EXPERT AT C++ :( . IF U HELP, I WILL FOREVER BE THANKFUL TO U!)

THIS IS THE MODIFIED VERSION WITH FILES

// Convert to string
itoa(intValue,myBuff,10);

// Copy the buffer into the string object
strRetVal=myBuff;

// Delete the buffer
delete[] myBuff;

return(strRetVal);
