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 ","?
or better yet, what if I want it to not matter whether the columns are separated by commas or spaces? is there any way to do this? If there is no way to read in both comma-separated and space-separated elements simultaneously then I would prefer just comma, rather than the space separated which my code is able to read now. What modifications would I have to make to my code to make this work? This is my code to reference.
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 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
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;
In my program I created three separate return functions. Each function is labeled:
int boxes(int x, int y); int leftOver(int x, int y); double avgItemsShipped(int x, int y, int z);
Is it bad programming practice to use 'x' and 'y' in all of my functions? Should I use the this keyword inside the function? We use this often in my Java class and I know it exists in C++, but I haven't actually seen it used (or used it myself yet).
I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream> #include <string> #include <sstream> using namespace std; int main() { string str = "3 J JD,K"; stringstream ss(str);
[Code] ....
Output of the code is 3 J JD k
but I want 3 J JD K
Also after I split the string is there any way to put the split string into individual string variables.
I want to put my socket programming example of how it can support multiple ports. I want to make the process more requests from distributing particles to create non-blocking structure
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
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.
Trying to append a comma to a string. Getting "Segmentation Error" on Solaris when the function is entered the second time.
Code:
// Appends a comma to the given string void appendComma(char* instring) { if (instring == NULL) { instring = realloc(NULL, strlen(",")); strcpy(instring,",");
Write a program that prompts the user to enter three integer values, and then outputs the values in numerical sequence separated by commas.
So, if the user enters the values 10 4 6, the output should be 4, 6, 10.
If two values are the same, they should just be ordered together.
So, the input 4 5 4 should give 4, 4, 5.
Code: #include "std_lib_facilities.h" int main() { cout << "Enter three integers, separated by space: "; int a, b, c, temp1 = 0, temp2 = 0; cin >> a >> b >> c;
[Code] ....
My first solution has a bug, so here's the corrected solution, written using only features I have learned in the first three chapters:
Code: #include "std_lib_facilities.h" int main() { cout << "Enter three words, separated by space: "; string a, b, c, temp; cin >> a >> b >> c;
function void EntryList::loadfile(const char filefoo[]){ ifstreamin;
[Code] ....
I am in the middle of rewriting this program for at least the 4 time. and I have modified the file how I (humanly) think I should to this. I have had issues in the past, doing it this way. (still working on the other parts of the program so I cannot be too specific right now, but I know my results were unexpected ) So my question is does the function that I modified look correct for what I am trying to do? Am I off by one? I guess I am struggling with understanding how the original function is working. (step by step systematically.) hence my confusion about my modified function.
I have a file with data in lines separated by commas and im trying to print out specific lines and specific parts of data from that line. I need to isolate lines where the first column of data reads '$CPGAR' and print out specific data columns.When I print out the strings I get random data and my strcmp to isolate lines isnt working? Im very new to this, heres a sample of my program:
while (!feof(gpsH)) { char word1[10],word2[10],word3[10],word4[10],word5[10],word6[10],word7[10], word8[10],word9[10],word10[10],word11[10],word12[10],word13[10]; char a[6] ="$CPGAR"; /* read data line */ fgets(gpsS,10,gpsH);
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.
