why the output of following c program is 16 16 16?

hope this fix your issue The output of following C program is 16 16 16, According to me output should be 10, as f2=f2+f2=4 now this f2=f2+2 will be 8, now a=a+2.5 which will make it 8+2.5=10.5, so 10 10 10 should get printed. But it is printing 16 16 16. , In your code fragment:
code :
    int a=2,*f1,*f2;
    f1=f2=&a;
    *f2+=*f2+=a+=2.5;
   int a = 2, b = 10, c = 20;
   printf("before: a=%d b=%d c=%d\n", a, b, c);
   c += b += a += 2;
   printf(" after: a=%d b=%d c=%d\n", a, b, c);
before: a=2 b=10 c=20
 after: a=4 b=14 c=34

Compare output of program to correct program using bash script, without using text files

fixed the issue. Will look into that further if [ "$TEST!"!="$CORRECT" ];
Looks like you have an extra ! in $TEST!.
code :
$ echo "foobar" > /tmp/test; TEST=`tail -n1 < /tmp/test`; CORRECT="foobar"; if [ "$TEST" != "$CORRECT" ]; then echo "failed"; fi
$
$ echo "barfoo" > /tmp/test; TEST=`tail -n1 < /tmp/test`; CORRECT="foobar"; if [ "$TEST" != "$CORRECT" ]; then echo "failed"; fi
failed

Program does not return output for large value of input such as 50.It returns 0.this is a factorial program using recurs

should help you out 50! is a very large number (over 60 digits) and 2^64 is less than 50!. The reason that you don't get the right number is that you get overflow, you are counting above the limit of what your computer can calculate.
code :
enter n 50

How to make PyCharm pipe python program output through another text processor program

To fix the issue you can do Update: I end up with a better (in my sense) solution: craft a startup python stub file run-module.py like:
code :
#!/usr/bin/env python

import os
import sys
import subprocess
import runpy

real_stderr = sys.stderr

if len(sys.argv) < 2:
    raise Exception('module name is required')

try:
    bi, bo = os.pipe()
    sys.stderr = os.fdopen(bo, 'w')
    subprocess.Popen(['bunyan', '--color'], stdin=bi, stderr=real_stderr)

    modu_name = sys.argv[1]
    sys.argv = sys.argv[1:]  # shift off run-module.py, argv[0] will be replaced by module's __main__
    runpy.run_module(modu_name, alter_sys=True)
except NameError:
    print('sys.path => %r' % sys.path, file=real_stderr)
    raise
except:
    import traceback

    traceback.print_exc(file=real_stderr)
    raise

How do i fix my output in my C program using format specifiers? the program is running but the output is not as expected

To fix this issue First thing I doubt that your code compiles, since in printf() you missed ',' :
code :
printf("\n\n\t\t Hi, %s ! You are %i years old.", name,age);
  char name;
  clrscr();
  printf("NAME: ");
  scanf("%s",&name);
char name[100];
  clrscr();
  printf("NAME: ");
  scanf("%s",name);

How to create a program in C that compiles and runs another c program and saves the output in a txt file?

seems to work fine It's possible. You either run a shell command that compiles and runs your subprogram (man 3 system, easy), or you go with more advanced techniques such as on-the-fly compilation (http://blog.coldflake.com/posts/On-the-fly-C++/ or https://bellard.org/tcc/ if you're a C programmer)
