| | Does it matter what you put in the array? If not, why not just fill it with the same number (e.g. - 1, 5, 19, etc. - whatever you like.) Or you could fill the array with some permutation of the indices of the array elements themselves. For example, a[i][j] … |
| | I can think of three examples: 1) nested for loops 2) nested while loops 3) nested do-while loops And they can all be nested multiple times, so have fun with them. |
 | >> "A while back I looked at SpiderOak which was promising just that in the near future. Perhaps it's time for another look." I recall that discussion from about a year ago: https://www.daniweb.com/community-center/geeks-lounge/threads/455113/new-kind-of-dropbox I have been using SpiderOak and it seems to work fine. Automatically synchs my files whenever a … |

| | You won't get good at Algebra just by reading a particular book; you only get good at it by doing it, and more, and more, and more. By reading several books, doing exercises, and coming at the info from different angles, the pieces will come into place and you will …  |
| | I am trying to understand some old FORTRAN code and have reached a point that puzzles me. In the main program, a 1-D work array has been defined. i.e. - REAL WORKA(30) Later on, portions of this work array are passed into a few sub-routines: e.g. - CALL SNAME1 (10, …  |
 | Each mailbox is either closed or open, so you could represent the mailboxes by an array of ints, which are assigned the value 0 or 1, to represent closed or open. Or an array of booleans. Start by assigning all of them to one value (say, 1) to represent closed. … |
 | I don't know if there is a way to automatically pull *just* reviews from one site to another; as far as I know, you get everything or nothing. Or perhaps you have a section of your facebook page specifically for testimonials, in which case you could restrict the content of … |
 | Re: Beards No beard (see photo from a couple years ago on my Twitter or LinkedIn page if curious). I sometimes let it grow for a few days, but it gets too itchy and starts to irritate the heck out of me--so I shave. Plus, I think it starts to show too …  |
| | Even *if* we wanted to work through this problem for the OP, I don't think there is enough information to answer the question. We don't know how much the seller marked it up in the first place. |
| | I am working with dynamic arrays which have been created using **<vector>**. For convenience, I have created a typedef : typedef vector<double> C1DArray; In the main program, several variables are created using this definition which, at the moment, means working with arrays of size 30. main() { . . . …  |
| | I am trying to convert some old FORTRAN code to C++. I am about three sub-routines deep into the code and one of the sub-routines includes the following line (twice): CDIR$ IVDEP This is the first time I have come across this command, or directive, or whatever it is. What … |
| | For the past while, I have gotten comfortable doing things a particular way when it comes to inputting data: i) create text file whose first entry is N, an integer indicating the number of data entries following, and the actual data entries. For example, for 101 data values, the text … |
| | Are you willing to purchase a compiler? If so, there are some commercial products available, for example, Pro Fortran 2014: http://www.absoft.com/ Otherwise, you might be interested in Open Watcom. I don't have extensive experiences with it myself. I downloaded it a couple years ago to test original Fortran code against …  |
| | I (finally) signed up for a Twitter account and am spending some time to customize my Profile. A few free services have been mentioned that provide this functionality: add URLs, change pattern, add LinkedIn URL, etc. -- basically, a template that prompts users to input their info and then outputs … |

| | The Wikipedia page for social networks is pretty extensive, but I can't think of any that I really recommend. But then, I am waaaaaaayyy behind the times anyhow. I haven't even joined Twitter yet. However, I am planning to change that and sign up within the week, to see what … |
| | It can also be done by postal code. For example, in the US, the ZIP code is used for accurately locating a region. I believe it is established by the USPS, but other shipping companies use it too (e.g. UPS, FedEx, etc.) It started out as a 5-digit code but …  |

 | The use of a URL Shortener, by itself, is not spam. It is used for many legitimate purposes (e.g. - in Twitter, to keep tweets within the 140 character limit). And they are offered by many different sources; in fact, even Google provides one (goo.gl). I don't think Google would … |
| | >> "Is the TAB going to replace the laptop?" No, I don't think so. I couldn't program on a tablet. Even a laptop is a bit awkward. I don't like being hunched over for hours when I am trying to write code. My preferred machine for serious code-banging is a …  |
 | I have stopped paying attention. Everybody else should too. They are like whiny babies: as long as they are getting attention, they keep whining. As soon as they are ignored, they shut up. It is the same rhetoric as always. And Quebec's reasons for grievances are getting lamer all the … |

 | Hello, Zubaer. You found one of them here. Welcome to Daniweb. Besides Daniweb, there are many others, but it would help to have more specific information.

| | I haven't been bothered by spam for a long time; most services have become pretty good at blocking it. Are you using a POP3 client or a webmail service? Besides adding filtering as suggested by "stultuske", you could also try to eliminate its generation in the first place. Do you … |

| | Re: Version Control Lots of good information being exchanged in this thread. I hadn't looked too deeply into version control before; the closest I have come to it was using Tortoise SVN on a small office LAN to maintain all the procedural documents.

 | I don't think forums are dying because of social media; from what I have seen, they are a poor substitute for the back-and-forth discussions that take place when somebody needs help with something. The groups on Facebook or LinkedIn simply do not offer that. Are forums dying, period? Perhaps some. … |
| | You are passing by value to this function. So the value (1200) gets passed into the function, not the actual variable. The function does not perform any manipulations on the variable and, even if it did, the effects would not be visible outside the function.  |

| | Re: Brute force If the password is maximum four letters long, you won't need an infinite loop. I think a combination of four variables can be arranged, at most, 4! times: `4! = 4*3*2*1 = 24`. (It has been several years since my last stats class, so I could be wrong. But there … |

 | Re: While Loops I haven't gone through this code thoroughly, but a couple things caught my eye. First, does this program compile? If so, what is it doing wrong? I don't think you need the break on line 27. If number==x the program should go back up to line 11 and break out …  |
