how to delete a file using c program

how to delete a file using c program

This c program deletes a file which is entered by the user, the file to be deleted should be present in the directory in which the executable file of this program is present. Extension of the file should also be entered, also note that deleted file doesn't go to recycle bin, remove macro is used to delete the file. 

Code

#include<stdio.h>

#include<conio.h>

void main()

{

   int status;

   char file_name[25];

   printf("Enter the name of file you wish to delete\n");

   gets(file_name);

   status = remove(file_name);

   if( status == 0 )

      printf("%s file deleted successfully.\n",file_name);

   else

      printf("Unable to delete the file\n");

  

   getch();

How to open thumbnail image in large view on facebook.

How to open thumbnail image in large view on facebook.
Please do-not Misuse it.

Step -1. Open any Facebook profile.

Step -2. Right click on the profile picture and click “Copy image URL”.

                                    Or

  Right click on the profile picture and click “Open image in new tab”.

Paste the copied URL in a notepad or address bar. you will see something look like this

fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/c120.0.720.720/s160x160/941834_691157654228570_1826110726_n.jpg

If you observe the above URL, you Will notice that the text in green color matches the thumbnail size of the profile picture.

Step #3. Now you have need to replace s160×160 with s720×720 in the above link , so your new link will look something like this

fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/c120.0.720.720/ s720×720 /941834_691157654228570_1826110726_n.jpg

Step #4. Now just visit this new url.

you have the original profile picture on your Screen.

Programming Challenges Question 1

Programming Challenges Question 

Write a program which will print the below structures according to the input provided to the program.
The program should accept 3 inputs in the form of numbers between 1 and 9, both inclusive (one number per line) and then generate the corresponding structures based on the input.
Suppose the following sequence of numbers is supplied to the program:
3
2
4

Then the output should be:
  1
 2 2
3 3 3
 1
2 2
   1
  2 2
 3 3 3

Programming Challenges Question 2

Programming Challenges Question 
Write a program which will accept a single pair of strings separated by a comma; the program should calculate the sum of ascii values of the characters of each string. The program should then subtract the sum of the ascii values of the second string from the sum of the ascii values of the first string.

Suppose the following input is given to the program: 

123ABC,456DEF

Then the sum of the ascii values of the characters in '123ABC' is 348 and in '456DEF' it is 366. The Difference between these numbers is 348 – 366 = -18
The corresponding output to be printed by the program is: 
-18

Kermit, a frog hops in a particular way such that:
1. He hops 20cm in the first hop, 10cm in the second hop and 5cm in the third hop.
2. After three hops Kermit rests for a while and then again follows the same hopping pattern.
Calculate the total distance travelled by Kermit (in centimeters) for the provided number of hops. Exactly 4 numbers of hops will be provided to the program (one number per line) as per the below example.

Suppose the following number of hops is provided to the program:
4
6

Then the total distance covered should be displayed as follows:
55
70
35
65
