Few of the functions declared in conio.h are taken from Pascal. Conio.h header file that comes with Borland compiler of turbo C video RAM to perform Output functions. As there exists more than one compiler each compiler has few functions declared in conio.h that differs from other compilers. The functions are declared in conio.h depends on the compiler. conio.h has many inbuilt library functions that are used to perform input and output from a c program.

If the room number doesn't match the 1-based index of the room in your array, the search will fail to produce correct is a header file used for functions related to console input/output. I'm not sure I completely understand your reproduction steps, but option 3 searches for a room index, but the prompts imply that you're searching for a room number. What is the error in my coding regarding this ? I m not able to see the added record again :(. I select 3rd option to see records but the record comes blank i.e. I'll also let gets() slide, but keep in mind that it's the worst possible choice for string input. I'll let someone else chastize you over using fflush() on an input stream, because it's obvious that you're using Turbo C++. I m bonded to use concepts of structure, functions, arrays and basics of c++, not more than that.
