how do I tell the if statement to output this error message 'exceeded the maximum amount of characters' that has its characters stored in an array using c-style string?
[INPUT] The cat caught the mouse!
[OUTPUT] Exceeded the maximum amount of characters (max 10)

Im working on a small code and am trying to limit the size of the mysql databse string its pulling.
It can only be 119 characters, or less if its more i would like to do nothing, but if its meets the requirements it runs the script.
Code:
int32 message_id;
string_t message ="Is requesting some one to respond.";<_______________TEMP SHOULD BE THE POSTERS MESSAGE
string_t username = "Guest";<_______________TEMP SHOULD BE THE POSTERS NAME
// char will not be logged in so get the id manually
[Code] ....
So here is where I'm heaving the problem
if(message is less then 119 characters run script )<<___________THIS IS THE CODE LINE IM TRYING TO LEARN
{
char buf[110];
sprintf(buf,"[Web Chat] %s %s",username.c_str(), message.c_str());

I am trying to make a double array, but I keep getting an error Segmentation fault (core dumped) when I make more than 105 elements in the array. I need to make 114 elements.
I am building my array with myarray[999] and increasing the number doesn't seem to do anything.
How can I store more elements in my array?
I have a firmware application that works well where I display simple text messages on an LCD screen. At the moment, the User Interface is only in English and I have the text strings simply declared as follows:
Code:
static char msg1[] = " Welcome ";
static char msg2[] = " Data Read ";
//etc...
I want to add a variable that can set the language dynamically from an external device, and so I thought I could do the following:
Code:
#define ENG 0
#define FRE 1
#define GER 2
//...
static char msg1[ENG][] = " Welcome ";
static char msg2[ENG][] = " Data Read ";
[Code] .....
writeLCD(msg1[cLang][]); When I try to compile the above I get a compiler error at the "static char msg..." declarations. The error is: "error: array type has incomplete element type"
Is this method valid, but I have a simple syntax problem with the arrray declarations? Or is this method unworkable and I should find a different method?
I have created a new array and have wrote a code which will decrease || increase the value of the array element. I been trying to figure out how to set the value limit. For Example:
int[] stock = new int[] { 10, 10, 10, 10 };
How to set a limit on the elements that they will never go below to the negative integers and over 10?
I was told that if I define
char *cstrp;
char cstra[c];
then the cstrp can be treated as cstra, and so I can also use
cin>>cstrp;
but when I write the following program, I find it don't work, don't have clue
#include <iostream>
#include <string>
#include <cstring>
using namespace std;
int main() {
char cstr[5];
[Code] ....
for cstr, it work exactly as what I expected, but for cstrp, no matter what I input, with a null terminator or not, I just got nothing printed. why? can we really use cstrp in that way or not? How to use it?
I am trying to read in data from a text file and store it inside a 3D array. The text file looks like this:
bar bell orange
bell bell 7
lemon cherry cherry
I can read in the data fine, but how to store it inside the array. My array looks like : [ Char slotMachine[10][3][8]; ] T
he dimensions are Row, Column, and symbol. There are 10 rows and 3 columns inside the file. The third dimension is supposed to hold the symbols as a C-style string.
This is what I have been trying:
char symbol[8];
int rowIndex = 0, colIndex = 0;
While(fin.good()){
fin >> symbol;
slotMachine[rowIndex][colIndex][] = symbol;
rowIndex++;
colIndex++;
}
I know that i'm not storing the symbol right. How to correctly store it inside the third dimension.
I am supposed to use scanf() for this assignment to limit the number of charachters in the string. However, I cant seem to get it to work in either scanf() or fgets().

Reading Effective C++ by Scott Meyers, and Item 16 claims that when an array is created, the compiler reserves a block of memory at the very beginning to indicate how many objects are in the array.
n = number of objects
|n|index0|index1|...etc
Scott Meyers wrote:This is just an example, of course. Compilers aren't required to implement things this way, though many do.
Supposedly, this how delete knows how many objects to destruct. And if you were to do something like:
int* foo = new int;
//Stuff
delete[] foo;
Then delete would interpret the first block as the number of items to destruct, then continue on and destruct that many blocks of memory onward, causing UD behavior.
Is there any truth to this?
What is the diff between strings and arrays? Here is sample:
By String:
#include <iostream>
#include <string>
using namespace std;
int main () {
string mystr;
[Code] .....
By arrays:
#include <iostream>
using namespace std;
int main () {
char name[256], title[256];
[Code] ....
which is preferable and can i pick characters one by one in string?
You will have two file streams: an input file stream for the file to be normalized and an output file stream that contains the normalized file. You should issue an error message and exit the program if either file cannot be opened. Your program should prompt the user for the filename of the file to be normalized (the input file). The output filename should be the input filename with ".normal" added to it. For example, if the input file is "data.txt", the output file name will be "data.txt.normal".
Be careful to not leave an extra blank line at the end of your output file.
My question here is how do I rename the file that the user entered to have a ".normal" at the end of it? I was thinking along the lines of having to string names and changing the second string's name and use that as the output file. any examples cause I didn't exactly get that to work.

Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.
Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.
Use the two data files named DATAX.TXT and DATAY.TXT.
You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.

or are they referring to something else?
What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello");
String t("There");
1. s = s + t;
2. s += t;
I previously tried to put strings in an array, but i couldn't modify the first index in the string that is in the array. I changed my code later.

Suggest a function that sorts the inputs vertically according to the order given by the user? I made this one
void order(string order, char index[][15]){
int counter=0,line=0,i=0,j=0;
for(i=0;i<=15-1;i++)
{for(j=0;j<=15-1;j++) {
if(index[j][i]==order[counter])

View 5 Replies View Relatedi have an array of strings that i need to split into 2 different string.
Code:
string title = " "Rebecca" "Alfred Hitchcock" ";
so far all the data is in one string called title
//need to break them into 2 strings, title and director
// title should contain = Rebecca
// director should contain alfred hitchcock
which string fuctions can i use to split these 2 and remove the quotes???
#include<iostream.h>
#include<conio.h>
void main() {
clrscr();
char name[5];
cout<<"Enter your name";
cin>>name;
cout<<"Your name is"<<name;
getch();
}
In the above program the size of the array of the variable name is 5. which means the variable cant store more than 5 characters.
which also means
If I give the string "LINISH"
It should only print LINIS
But while the program is running, Even if I type a 10 characters string, It is getting printed Completely..why?

#include<conio.h>
void main(){
clrscr();
char name[5];

In this program when I input a string for the variable name,It is getting printed completely, irrespective how many characters are there in the string.But If the string (which is input to the second variable that is game )holds more than 5 characters. the input of the first variable(name) is getting disturbed..why?
look at the below cited output to be more clear about my doubts.
OUTPUT NO:1
Enter your name:LINISHFRANCIS (Note that the input holds more than five chars)
Enter your game:GOLF(input is less than five chars)
LINISHFRANCIS loves GOLF(Two inputs are getting printed comopletely)
OUTPUT NO:
Enter your name:LINISHFRANCIS (Note that the input holds more than five chars)
Enter your game:FOOTBALL(input is more than five chars)
ALL loves FOOTBALL [Note that "ALL" is the last three letters of FOOTBALL

Where i can get ready function, which return string, which describe size of file?

I'm writing a code generator that produces a function from the strings to the ints. I'll be using the generated code as a "from string to enum" utility. For example:
Code: enum Color {
Red, Green, Blue, Banana
};
// The definition of colorFromString is generated somewhere.
Color colorFromString(const std::string & s);
[Code].....
The implementation of the generated code is a trie. I've seen implementations in the past (including the one at work that I'd like to replace).
Anyway, say you need to compare the region of the string
Code: const char s[] = "holiday"; from index 3 until before index 6 against the string "ida".
I can see two bits of code that my generator could produce. One is
Code: bool hasIda = std::equal(s + 3, s + 6, "ida"); and the other is
Code: bool hasIda = s[3] == 'i' && s[4] == 'd' && s[5] == 'a';
The existing code generator uses the latter method, claiming (I think) that the generated instructions are more efficient on some architectures. Is there any way to determine which is better generally, or do I have to examine the assembly produced on all target platforms?
Is this possible in c++:
Code:
string s = R"(some rand string)" + argv[4] + R"(some rand string1)";
if it isn't, what is the best way to do this?
My program will scan a message sent over Steam (An online game distributor ) and I want it to check if the Message contains one of the elements in the array. I want it to compare the String of the message to the values in the String array. I have tried looking into it but have unfortunately found nothing that would go along with my program outline. Here is my code so far:
if (add == true) {
string[] itemNames = { "keys", "tickets", "nametags", "descriptiontags" };
string[] splitmessage = message.Split(' ');
foreach (string word in splitmessage) {
int strNumber;
