NOTE : All the programs are tested under Turbo C/C++ compilers. **
It is assumed that,** *=> Programs run under DOS environment,**
*=> The underlying machine is an x86 system,** *=> Necessary
header files are included.** *=> Program is compiled using Turbo
C/C++ compiler.** The program output may depend on the information
based on this assumptions. ** (For example sizeof(int) = 2 bytes
may be assumed).
