The average temp over the past 100 years has increased a whopping 1 degree F. Scary!!! :S So if this uncontrolled rise in temp is not checked, we'll be in danger in about 3564AD. '[I]Global warming[/I]' is a naturally occurring phenomenon that is cyclical.

[QUOTE=BestJewSinceJC;733868]From when I programmed in C, I remember that output stream redirection is done by a.out > filename.txt or a.out < filename.txt I don't remember which.

Please read [url=http://www.gidnetwork.com/b-58.html]this[/url] about using [ICODE].eof()[/ICODE] the way you are (it's the same as using [ICODE]feof()[/ICODE]. And read [url=http://www.gidnetwork.com/b-38.html]this[/url] about formatting your code so it can be understood.

[QUOTE=Ancient Dragon;728164]The code you posted will have undefined behavior. [icode]cube(++x)[/icode] could result in different answers on different compilers, so the ourput can not be determined exactly.[/QUOTE] Why? It increments [B]i[/B], calls [ICODE]cube[/ICODE] with the new value, then returns the answer to [B]y[/B]. What's undefined about it? [B]i[/B] isn't modified twice.

No

No wonder those links don't help. They have nothing to do with the problem. First off, [I]res[/I] is already binary. If you know the shift operator ([B]<<[/B]), that makes it easy to count the 0's. Look it up and see what you come up with.

Every solution proposed here has major problems -- that of trying to read an integer when a 'not a number' can be entered which screws up the entire read process.. You need to read [I]an entire line[/I] as a string, test all characters entered up to the '\n' to make …

[QUOTE=keyser_soze;726512]i think u might use the getch() putch combination use getch to enter the charcter one by one and then using putch print out * example: [code=c] getch(password[x]); //where x runs in a loop from 0 till NULL putch('*'); [/code] PS:go through this thread [code][url]http://www.daniweb.com/forums/thread9916.html[/url][/code] has a better detailed solution....[/QUOTE] …

When you find you have a parameter that starts [B]-t:[/B], use [ICODE]strcpy()[/ICODE]: [code=c]strcpy(websitename, &argv[p][3]);[/code] [B]p[/B] is of course the parameter number [B]3[/B] points to the character after the colon

[code] strcpy(input," "); // You don't need to do this if your next // line overwrites the value scanf("%s",&input); // [url=http://www.gidnetwork.com/b-62.html]see this[/url] fflush(stdin); // [url=http://www.gidnetwork.com/b-57.html]see this[/url] [/code]

You need to change your increment: [code=c] case 5: //move forward x number of spaces int steps = commands[ ++cmd ]; [/code] This will increment [I]before[/I] you load [I]steps[/I], getting the number of steps.

You need to test the value after reading it. If invalid, start the loop.

To all of you, floating point values are rarely exact. Therefore testing with == will rarely work. For example, if you entered 46, the actual value stored in the variable might be 46.000001 or 45.9999997, neither of which is equal to 46.

[QUOTE=SQ89;723738]Thank YOU :) but can you explain to me how col works?? i mean in the if statement[/QUOTE] Every time you output a number, you increment [I]col[/I]. When [I]col[/I] is 3, 3 number have been displayed (3 cols) so you drop to the next line and reset [I]col[/I] to count …

So much help, so little correct :icon_rolleyes: To find the lowest value, store the first value read in a variable, say [I]lowest[/I]. Then for each successive read, test the value read against [I]lowest[/I] and replace if necessary.

[QUOTE=kalou;723393] i need a help so badly.[/QUOTE] Then you should have read [I]The Rules[/I] and the post [I]Read This Before Posting[/I]

I agree with [B]thwee[/B] -- the [ICODE]for(;;)[/ICODE] is nonsensical. If you are trying to keep your program window open, just do the [ICODE]get()[/ICODE]

Did you call [ICODE]srand()[/ICODE] only once? Or every time you called [ICODE]rand()[/ICODE]?

Also speak English, not pigeon-speak. And use CODE tags. They are described everywhere on this site.

You might be able to use the built-in functions [ICODE]ispunct()[/ICODE] and [ICODE]isspace()[/ICODE] to 'tone down' some of the long windedness.

[QUOTE=Sci@phy;715626] They differ a lot, since turbo c++ compiler is ANCIENT. There is something that is called standard C++ language.

[QUOTE=Ancient Dragon;712707]after entering an integer the program leaves the '\n' in the keyboard buffer.

[QUOTE=ahamed101;713331]As per you, it is C, then this is the right forum... And what makes you say, its c++??...[/QUOTE] The actual questions deal with the calculations, not the output statements. They are fully C++ as well as C. And [ICODE]printf()[/ICODE] is a C++ function. Check any C++ book/tutorial/standard.

And posts should NEVER be marked urgent! It's not urgent to us -- we'll get to it when we get to it. And many people simply bypass threads titled like this so you've just cut down your chances for help.

[B]stilllearning[/B] is correct. The compiler is only interested in the statements that do something so comments are not part of the compiled program.

[QUOTE=EBaller55;704374]It would be nice because then I could do the following: [code] for(int i=0, double d=1;i<5;i++,d*=1.5){cout<<"1.5^"<<i<<"="<<d<<endl;} [/code] This would make for cleaner code as it is clear that i and d are used only inside the for loop.[/QUOTE] I disagree.

Nothing else is output to the screen. What do you expect to happen? If you think there's a problem, add a few [ICODE]cout[/ICODE] statements to follow what's happening and pinpoint the problem.
