input and output programs

---

Here are some programs with solution. The solution is also provided with  explanation such that you can understand  it easily.
Before you go for program, ensure yourself that you have sufficient knowledge about theory. If not then you can go to tutorial section of C.
                            First you try yourself and if you could not then you can click "show the solution".button.
You can put comment if any problem arises or if you want to go for theory then you can go to
  tutorial section of "C".
 You can get solution of programs given in books of different national and international authors.
                   Following are some programs related to input and output functions
