C/C++ :: Taking String As Input And Making It As Whole Array (string Literal)
Oct 19, 2014Very new to programming, and I know that there must be another way on inputting a string into each array cells not by just inputting it one by one, but as a whole. My code at the meantime is: [URL]

C++ :: Input String Text Into String Array
Jun 26, 2014/*assume array is already initialized and declared and is of array type string.*/
int i = 2;
int j = 1;
string newvalue;
cout<<"Current value at array[i][j] is "<<array[i][j]<<endl;
cout<<"Enter new value "<<endl;
cin>>newvalue;
array[i][j]= newvalue; //PROBLEM IS IN THIS LINE.
cout<<endl;
cout<<array[i][j]<<endl;
I'm having lots of trouble with storing a cin string text into a string array. It just seem that after I cin newvalue, the program crashes. Is this way of storing it considered illegal? I'm just a beginner with 5 months of coding experience in C++.
C++ :: Char Array To String - String Becomes Garbage
Apr 20, 2013I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.
// Get value from ListBox.
char selectedValue[256];
memset(selectedValue, NULL, 256);
SendMessage(GetDlgItem(hWnd, IDC_LB_CURRENTSCRIPT), LB_GETTEXT, selectedIndex, (LPARAM)selectedValue);
// Convert to string.
string val(selectedValue);

C/C++ :: Enter String Into String Array Via Cin Or Getline
Mar 29, 2014Ok so I searched this site, and google string arrays, but I couldn't find anything on how to create an array to accept string input. In other words the strings are unknown, until the user inputs them..
so code would say input a name..user enters Tom, and its inserted into the array.. and if another name is entered ..lets say Lisa..Lisa is added to the array..so now in the array we have tom and Lisa..
Everything I read only shows the array already having the strings declared...
string n;
string name[n]={};

C++ :: Changing Array Of Characters To A String Array?
Apr 7, 2013I have an array titled: char TypeOfSong[arraySize] where the array size is 15. I am reading data from a file into this array and the characters can be either 'C', 'D', 'E', or 'R'. Each of these characters stands for a word (sting) and when I output the array, I need the strings to show up, not the characters. I have been reading online and in my book but I can only find information on turning one array with the same characters into a string. How would I go about changing this character array with different characters into a sting?
The characters stand for:
C = Country
D = Dance Party
E = Elevator
R = Rock

C++ :: Char Array To String
Oct 19, 2013I have some code:
char cHomeTeamFaceOffsPercentageWon[100];
memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100);
After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%".
Then, I use
std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon);
szwPercentageWon is then, "2". Shouldn't this convert correctly, to "29%" as well.
Or is there something I'm missing? Maybe the termination character, or something.
C++ :: Access To Array By String Of Its Name

C++ :: Convert Int Array To String
Nov 5, 2013I'm trying to convert int x and y arrays to string using a sample code found online.
string Square::int2string (int x[]) {
string returnstring = "";
for (int i=0; i < 4; i++) {
returnstring += itoa(x[i]);
return returnstring;
}
}
but hit with the following error.
Square.cpp:30:8: error: prototype for ‘std::string Square::int2string(int*)’ does not match any in class ‘Square’ Square.h:21:10: error: candidate is: std::string Square::int2string()
I declared the following in header file.
string int2string();
The error is due to variable type does not match. Is there a better way to convert int array to string?
What I'm trying to achieve is a string printed in the following manner:
Point[0] (x1,y1)
Point[1] (x2,y2) and so on.

C++ :: Length Of String Array?
Sep 7, 2013I can't find any method of retrieving the length of an array except for doing this:
string first[] = {"a","be","see"};
int length = sizeof(first)/sizeof(first[0])
This is a very unconventional way of getting the length of an array.
first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).
first.size() would return 1 aswell as it's practically the same thing.
Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it?
Is there no buildt in method for this? If there is not, why has it not been implemented in the std?
C++ :: Declaring Array To Be String?
Mar 18, 2013I'm writing this program that basically interprets the rottentomatoes website. I am however having a problem declaring if it is rotten or fresh according to the rating the user enters.

WriteLine('=', 50);
cout << "PRINT ALL" << endl;
WriteLine('-', 50);

And here is my condition:

string rank;
for(int i = 0; i < count; i++) {

C++ :: Finding A String Within Array?
Jan 14, 2013i just want to check to see if one word (string) or one sentance is equal to any others within an array. My code
so basically i want to check if a is equal to either "sleep", "in", or "bed". Or even if the string within a is equal to "sleep in bed" as one string.
I have used the following but even if i get it correct and it says correct it says incorrect another 2 times because it is saying yeah you have gotten one right out of the possible 3. Even if I type "sleep in bed" it still does it (prints out incorrect another 2 times. Also are there any good books to start off with c++?
string a;
string aa[3] = {"sleep", "in", "bed"};
for(int i = 0; i < 3; i++) {
if(a == aa[i]) {
cout << "CORRECT!" << endl;
} else {
cout << "INCORRECT!" << endl;
}
}

C++ :: Assigning String Tokens To Array?
Oct 20, 2014I need to dynamically build a control file for a SQL loader but when tokenizing line values read from a file i am unable to work/assign the last value to a variable even though i can print the actual token value while in the loop.
Below is the code snippet i have and get:

C++ :: Converting String To Char Array
Mar 30, 2014In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);
