C C++
1. C is Procedural Language. 1. C++ is non Procedural i.e Object oriented Language.
2. No virtual Functions are present in C 2. The concept of virtual Functions are used in C++.
3. In C, Polymorphism is not possible. 3. The concept of polymorphism is used in C++.
Polymorphism is the most Important Feature of OOPS.
4. Operator overloading is not possible in C. 4. Operator overloading is one of the greatest Feature of C++.
5. Top down approach is used in Program Design. 5. Bottom up approach adopted in Program Design.
6. No namespace Feature is present in C Language. 6. Namespace Feature is present in C++ for avoiding Name collision.
7. Multiple Declaration of global variables are allowed. 7. Multiple Declaration of global varioables are not allowed.
8. In C

  • scanf() Function used for Input.
  • printf() Function used for output.
8. In C++

  • Cin>> Function used for Input.
  • Cout<< Function used for output.
9. Mapping between Data and Function is difficult and complicated. 9. Mapping between Data and Function can be used using “Objects”
10. In C, we can call main() Function through other Functions 10. In C++, we cannot call main() Function through other functions.
11. C requires all the variables to be defined at the starting of a scope. 11. C++ allows the declaration of variable anywhere in the scope i.e at time of its First use.
12. No inheritance is possible in C. 12. Inheritance is possible in C++
13. In C, malloc() and calloc() Functions are used for Memory Allocation and free() function for memory Deallocating. 13.In C++,  new and delete operators are used for Memory Allocating and Deallocating.

Installing SRAC Code on Mandrivalinux 2010.0 x86_64

Posted by Syeilendra Pramuditya on January 18, 2016

SRAC: Standard Reactor Analysis Code, developed by Japan Atomic Energy Agency

SRAC code was developed long time ago, so there are problems when you try to install it on modern linux distros. The biggest problem of all is I think the original SRAC works only with F77/G77, whereas modern linux distros usually only provide gfortran.

Some installation tips:

Tip 1

Using the control panel, make sure that the following packages have been installed: gcc-cpp, gcc-c++, gcc-gfortran, tcsh, make, automake, ncompress, mscompress

Tip 2

Edit these 2 files:

SRAC/tool/install/SysDpnd/linux-g77/PrepInst.sh

SRAC/tool/install/SysDpnd/linux-g77/lmmake/lmmk/lmmk.sh

Open the files, you will see “set F77 = G77”, add a new line after that line: “set F77 = gfortran”

Now you just test run the code by executing SRAC/smpl/shr/Test.sh

Sample of input and output files are available here.

This has been tested and works for me.

*Of course you can just simply install SRAC 2006 which supports gfortran compiler.
