Practical 3 Hours/Week 1 Credit Marks: 25

Note:
• Programs of all the Concepts from Text Book including exercises must be practice and
execute.
• Faculty must take care about UG Standard Programs.
• In the external lab examination student has to execute two programs with compilation
and deployment steps are necessary. Write the Pseudo Code and draw Flow Chart for
the programs.
• Recommended to use Open Source Software: GCC on Linux; DevC++ (or) CodeBlocks
on Windows10.
• External Vice-Voce is compulsory.
