C/C++ :: Separate Comma Delimitated Data With Spaces?
Mar 7, 2014
I am having a hard time trying to get data into an array of objects. The data file has 3235 lines, state, fips code, and county. The state and fips code are getting stored correctly but some countys have 2 or more words in them (now noticing the "and" is missing from one of them.
sample of the file:
AL,01,123,Tallapoosa
AL,01,125,Tuscaloosa
AL,01,127,Walker
AL,01,129,Washington
AL,01,131,Wilcox
AL,01,133,Winston

I want to separate this binary string every 4 characters..I am trying to get a better understanding of how variables are stored in memory and I am looking at their binary address for a pattern..I see a pattern for the last 4 bits
#include <iostream>
#include <bitset>
int main() {
using namespace std;
int x[100];
[Code] ....

I am attempting to read in a file that has 4128 sets of 21 numbers separated by commas and write it into an array. I now know that in order to use fseek, I have to make my array a character array, but I need my function to read in decimals (ex: 0.172635). I'm reading in
0.102598,0.000000,0.000000,0.000000,0.000000,0.307 793,0.000000,0.410391,0.102598,0.000000,0.102598,0 .102598,0.000000,0.000000,0.102598,0.102598,0.8207 83,0.000000,0.000000,0.000000,0.000000
and keep getting numbers like 48 49 50.
Code:
void CSread(char filename[100], char array[22], char array2[22], unsigned int arraysize)
{
char genename[32];
double temp = 0;
FILE *CSfile;
CSfile = fopen(filename, "r");
");

fscanf (fData, "%c", &grade);
fgets(space,2,fData);
do{
fgets(name,50,fpData);

I have a string that receives a value, with comma eg 11,222
How do I convert a string to comma point?
I'm trying to convert the string to float, however because of the comma does not handle values before the comma
float to_float(const std::string& str)
{
std::istringstream is(str) ;
float result;

I am trying to write a way to properly format numbers by adding "," to numbers. Ex:
1000000 -> 1,000,000
30000000000000 -> 30,000,000,000,000
In the usual case, its an easy problem. But it gets tricky in my case, since I am working with numbers up to 30 digits, unable to store them in any int, long, long long. Due to this obstacle, the user inputs a number and each digit is stored in my array individually.
I need these commas to print as I am cout the array. This means I only have array length to work with.
I want to use modulus, but I'm not sure how this would work. I have:
void prArray(int Array[], const int arrSize) {
int mod = arrSize % 3;
int remainingSize = arraySize;
int counter = 0;
for(int i=0; i <= arrSize; i++){
remainingSize--;
[Code] ....
Which outputs the first digits correctly, but leaves 4 digits at the end:
235423452345 -> 23,542,345,2345
Likewise
2354234523450 -> 235,423,452,3450

I'm trying to read names separated by a comma using array.
For example, the expected input would look like the following:
Juila,Francisco
Adams,Wong
I know you can use getline function and set the delimiter to comma. So like ....
getline(cin, lastName, ','); getline(cin, firstName);
But the program only read the last name and ignore the firstname.

TinyGPS::TinyGPS()
: _time(GPS_INVALID_TIME)
, _date(GPS_INVALID_DATE)
, _latitude(GPS_INVALID_ANGLE)
[code]....
I am wondering about the constructor. I see there appears to be nothing inside of TinyGPS::TinyGPS() as far as parameters go and that that declaration is followed by a ":". First I'm wondering as to the meaning of the colon. As well with the variables defined after the ":" I see some "(0)" and I am wondering as well to the exact meaning of the "(0)". Are those variables being defined as parameters separated by ","?

I'm trying to enter an 'x' and 'y' coordinate on only one line separated by a comma. But I keep getting a syntax error. Here are the lines of code I'm using. This has to be simple. What am I doing wrong with this code?
Code:
cout<< "Please enter the x and the y coordinates of the first point,"<<endl;
cout<< "use a comma to separate them. " <<endl<<endl;
cin>> "You entered: " >>x1>>",">> y1 >>"for the first point" >>endl;

I have been trying to read a comma separated .txt file into an array and print it to console in C++. The txt file consists of two columns of double type data. For some reason the program runs, but gives blank output in the console. I want to know if I am doing something wrong. So far this is what I have:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
int i=0;
double x[10];
double y[10];
string line;

I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
Code:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
vector <string> v_input;
int main() {
ofstream fout ("Insert File Path Here.txt");
fout << "4, 8, 15, 16, 23, 42";

I am practicing with C++ since I done most of C already and I have a problem with reading spaces from a .txt file.
I created a little program that creates a wannabe Cube in wannabe 3D xd, well to appear as 3D like:
Code:
cout << " O------O" << endl;
cout << " / /|" << endl;
cout << " / / |" << endl;
cout << " / / |" << endl;
[Code] .....
The actual code is a bit longer since it offers you to input the size and then it draws the pic. Now that wasn't so hard and I've done that but now I wanted to implement the "MessageBox" func for output.
I managed to write the cube in file cube.txt but when I'm reading from it 1 char at a time since I need to output as char array it avoids all spaces and new lines and just puts all symbols in the same row.
I didn't have that issue with C and I've found on stackoverlow a solution using strings & getline but I need it to be in "char" form.
How to actually read spaces and newlines? This is my current code for reading from file:
Code:
ifstream di("kocka.txt", ios_base::in);
char c[5000];
int br=0;
while( di >> c[br])
{
br++;
}
MessageBox(NULL, c, "Kocka", MB_ICONHAND);
di.close(); P.S kocka = cube (in croatian )

Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?
Code:
#include <stdio.h>
#define TAB_STOP 8
int main()
{
int c, i;
}

I want to store the address of a customer (with spaces) in a char variable (say cadd). First I tried to use "cin", as we know it reads until it sees any whitespace. So it reads only first word before a white space. So, I used "getline()" function. But when I used it, It didn't wait for the I/P (it skipped it).
char cadd[20];
std::cout<<"Enter Customer Address:
";
std::cin>>cadd;
std::cout<<"Enter Customer Address:
";
std::cin.getline(cadd,20);

I will post the entire code at the bottom. Its running fine right now but This part in the menu function I need to make as a separate function. My problem is when I make it into a function by itself I have to declare and initialize the grades A,B,C,D,F how can I do that when I can't make them equal 0 because it has to keep track of how many of each letter grade.
Code:
//Count letter grade
if(ave >= 90)
++A;
else if (ave >= 80)
++B;
else if (ave >= 70)
++C;
else if (ave >= 60)
++D;
}
