RAILWAY SEAT RESERVATION PROJECT

RAILWAY SEAT RESERVATION PROJECT

Description: This C++ program on RAILWAY SEAT RESERVATION is a simple text base program.We have used procedure oriented method to design this program. This program is without grahics to keep program simple for beginners.

 in a trian compartment there are 67 seats...13 rows of 5 (3 by2) setats and the last row has 2
