i just tuned my low e string to C so it would sound better when playing SOAD seeing as how most of there songs are on only one or two strings.
its tuned to C but its really loose and buzzes off the frets so im not sure if its right
How do i know if my bass is tuned to C correctly?
If you're going to tune down that far, you'll need thicker strings, and possibly a neck tweak.

Java equivalent to System.Text.StringBuilder in C#?
I want to build a very large string from lots and lots of small strings. In C# I would use System.Text.StringBuilder without hesitation. At present I am using java.io.StringWriter, but I am concerned that it may not be efficient enough? Is there a better option? MUST be FAST! Thanks in advance.
Java equivalent to System.Text.StringBuilder in C#?
That is not what StringWriter is for. StringWriter is a character-based output stream that writes the bytes to memory.
Use java.lang.StringBuilder. It was added in Java 5 (JDK 1.5). It is similar to java.lang.StringBuffer, but without the synchronization. So, if you plan on designing your program such that only one thread will be using it, use the StringBuilder.

C - How do I save data in a text file?
I have made a maze game in C and am stuck on how to get a user name and save the username and score on a text file. I don't know much about string in C except that "it is an array of characters". I know a user name will need to be string so I am using this:
char username[3];
scanf("%s", username);
I am assuming the variable 'username' will be saved to a file but I do not know how to do this. Any ideas?
C - How do I save data in a text file?
You need the following basic steps:
FILE *fp; //create a file pointer
fp = fopen("file","w"); //open "file" for writing "w"
//check if the file was opened without errors
if(fp==NULL) {
printf("\nCould not open file.. aborting!!");
exit(1);
}
//write to file - you have a number of options here - read more about the functions to suit the formatting and data you need to write to file - one example below:
fprintf(fp, "%s %d", username, score)
fclose(fp); //close the file pointer once you are done writing to the file.
Reply:Use fprintf() function or fwrite() function. Refer the page given below...

Question about strings in C?
When reading in strings, how can I include spaces in the string?
What I mean is that, normally, you'd need something like
scanf("%s%s%s", %26amp;str[0], %26amp;str[1], %26amp;str[2])
to take something like
"one two three"
and read it in as three strings.
How can I read in "one two three" as one string? That is, without the program assuming that spaces are breaks between strings?
Question about strings in C?
You can use scanf as below to read until end of line.
scanf("%[^\n]",%26amp;str[0]);
That should work.
All the best !
Reply:fgets gets the entire line.
If you want to read in more than a line you must use fread.
Then parse it manually.
P.S.
I personally don't use scanf to read in strings from stdin because it's a potential buffer overflow(security risk).
If you are going to use scanf specify the field width %10s or use %as to allocate the string.ualifier is present, the next pointer must be a pointer to
wchar_t, in

C programming question?
Given the following declarations:
char a[ ] = "abc", *p = "def";
What is the effect of the following statement?
p=a
a. It copies the string "abc" into string p
b. It changes p to point to string "abc"
c. It copies the first character of a ton the first character of p
d. It generates an error
C programming question?
haha cheater.
ya D) is looking good.
Reply:Genrates Error
Reply:b.
p is a pointer to char.
The name of the array a is also a pointer to char.
Reply:b. p will point to a which contains "abc".
Reply:The answer is b.
I just wrote a little code to do it, although I should have been smart and just looked at K%26amp;R.
Reply:p will then point to the first position of a, it won't point to the whole string but you can use pointer arithmatic to get the rest of the string. So - E. none of the above.
Reply:Usually it would be b. Because you replaced the adress the pointer points at. But i am not quite sure you can declare a pointer on a string constant (*p="def") - it would probably generate an error.
char a[ ] = "abc", *p = "def";

How do you reverse a string? In other words if I have "It is hot today", I want to get "today hot is It".
How do you reverse a string in C/C++?

hmmm, sounds like you should read your text, perhaps post some code and then ask for some help. this might lead you in the right way:
#include%26lt;iostream%26gt;
#include%26lt;string%26gt;
int main()
{
using namespace std;
string txt;
cout%26lt;%26lt;"Enter anything, come on, anything...\n";
getline(cin,txt);
string::iterator end = txt.end( ) - 1;
for( ; end != txt.begin( ) - 1; end--)
{
cout %26lt;%26lt; *end;
}
cout %26lt;%26lt; endl;
system("pause");
return 0 ;
}
Reply:just reverse the string i guess
and in arrays if it from 1 to 5 it will count 12345 but if u reverse it as 5 to 1 , it will show 54321
good luck
Reply:Technically you are not reversing a string. You are reversing a subset of items inside a string.
So you would have to create an array of strings. Parse the contents of your original string by some separator, such as a space.
Then just reverse loop through the array of strings.

How can i manipulate string to know whether the substring is contained in the string?
how can i manipulate string in c++ to know whether the substring is contained or have a pattern in the string?
but,without using strcmp.

Saw this yesterday...
Reply:in C/ C++ i would go for the library function strstr();
in JAVA, str.contains(str1) would do the trick, where str is the string in which str1 has to be searched
