Considering the Code $5$ in Kundu et al$.,$ for solution of one$-$dimensional compressible

Euler Equations, add the capabilities to the code for obtaining:

a$)$ The plots shown in Fig. $6-26$ plus the converged specific energy values along the

length of the tube.

b$)$ Plots of Mach number, density, internal energy and pressure variation in time at user$-$

selected grid points.

Re$-$run the code and submit the modified code and the obtained plots. Show the

modifications made and discuss the results.
