C++ :: Parsing String To Contain Inputted Int
Sep 10, 2014
I have been here for almost 3 months looking for answers in my C++ problems.here's some type of code for this.
cout << "Enter value of x: " << endl; //Let's say 5.
cin >> x;
cout << "Enter equation: "; //Let's say x+1
cin >> equation;
Then the program analyzes that this character "x" has an initial value of 5.I already have the parser for the equation functions (+,-,*,/)This is the only thing lacking. Is there some type of function that i missed?

So imagine you have this string:
"somedata here "some data here" some more data here"
I need to parse this:
somedata here "some data here" some more data here
I tried to do it with Regex and was capable of parsing
[0] = somedata here
[1] = some data here
[2] = some more data here
Here is my current code:
string Buffer = string.Empty;
foreach (Match match in Regex.Matches(strLine, "".*?""))
Buffer = match.ToString();

I have an input file that contains any number of lines. Each line will follow the same structure. There will be 5 fields, separated by 4 commas. Fields 1 and 3 will be single characters, fields 2,4,5 will be integers. Example:
<A, 123, B, 456, 789>
I need to iterate over each line, parse out the fields, and capture each field value into a separate variables.
header file: Code: #include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>
[Code]....
I've used similar code to this before, but this time I'm getting the dreaded pointer from integer error on my strtok lines:
warning: passing argument 2 of 'strtok' makes pointer from integer without a cast'

How do I create a function that can understand trigonometric functions?
Examples:
if I am to input: x^2 + sin(x)
The program will understand the the value between parenthesis preceded by a string "sin" will be computed as the sine of x. of any function in case.
I have the program here.
#include <iostream>
#include <cstdlib>
#include <cctype>
#include <cstring>
using namespace std;
enum types { DELIMITER = 1, VARIABLE, NUMBER }; //DEL = 1; VAR = 2; NUM = 3.
class analyzer {

Program works perfectly fine. I input in the length, width and height. But i want it to display those values for every individual prism when i output... along with the area and volume which i already have. Since i made a vector i won't let me cout it normally.

#include <vector>

I need to allow the user to input an integer of any length and print out the word of each number in the integer. So the user would enter "324562" and then the output would be "three two four five six two". I'm struggling to understand the best way to do it in C. I know I need a loop that goes through the int but I don't know how to do it

I came up with this code to try to add each number from a zip code inputted by the user but I think I'm adding up the ascii values not the real values the user is inputting. How I can go from ascii to the real digit. This is my code so far
#include <iostream>
#include <iomanip>
#include <string>
#include <conio.h>
using namespace std;
int main() {
int total = 0;
char ch[5];
cout << "Please input your 5 digit zip code: ";

I've been working on this program and I have it all pretty much down, but I just need one thing that I can't, for the life of me, think of! I need to find the reciprocal of a number that the user inputted (ex: if user input was 2 output would be 0.5 or if input was .6, out put would be 1.6 repeating). If theres a simple way, I can't think of it.

I've written a program which takes a character string and then prints each character vertically so that for instance the string 123 can be written as
1
2
3
no what i need is for all the numbers from zero to the inputted number to print the numbers digits vertically but each number to be printed horizontally so that for instance an input of 11 prints
1 2 3 4 5 6 7 8 9 1 1
0 1
i've made it so that i can print all numbers up to the inputted number vertically; however, i am stuck with a method for making each number print horizontally as described above.

I'm parsing an xml file full of payslips and using the data in another application. I've got it all working but I suspect it isn't the most elegant piece of code. I run through the xml file finding a series of "Text" attributes/elements" and then I run through it again finding a series of "Field" attributes/elements, Here is a sample of the code:
For getting the "Text" fields :
XNamespace ns = "urn:crystal-reports:schemas:report-detail";
//
// Get all the Text attributes & Elements
//
foreach (XElement xtxt in xdoc.Descendants(ns + "Text"))
[Code]...
This works fine, I extract all the data I'm interested in and go to do my thing with it. However I really need to know when each record ends and I was doing that by looking for "Text24" in the text fields and "EeRef2" in the field fields, which wasn't very elegant in the first place. Then a "Text16" was added to end of each record which was fine I could just look for "Text16" but now it's apparent that "Text16" isn't always there. I've got it all working for now but I'd prefer to process one record at a time i.e. extract all the "Text" & "Field" values for one record, do whatever I need to do with it, update the xml file to indicate this progress ( if possible ) and then move on to the next record. I've attached a sample of the xml but basically is has the following structure :
<Details>
<Section>
<Text></Text>
"
<Field></Field>
[Code]...
So a record is everything between the first <Details> and the last </Details> with two <Details> and two </Details> in between.

The program is supposed to have a method called Hitscore that adds a score between 0 and 1000 inputted by the user to the total score and increases level by one and print the score to the screen and which level they last completed after each entry . Have the user continue inputting scores to the program until the gamer has finished all 10 levels. After 10 levels, use a method you create called PassScore to have the program compare the score to avgscore (5000). If the score is less than avgscore, have the code respond "You are not angry at all. " if it is above avgscore, then have it respond "You seem quite angry, calm down. " and if it is exactly 5000, have it respond "Average, just average. "

Suppose I have read a line from an ASCII file with fgets(). Now I want to parse the line, which looks something like this: Code: # John Q. Public et al. 2014, to be submitted The name, "John Q. Public" is what I want. However, the name can be anything, consisting of 1 or more tokens separated by spaces. it could be "John" Or "John Public", or "Thurston Howell the 3rd", or etc... Bascially, I need to get the entire substring between the first hash mark, and the "et al" in the line. I tried this: Code: sscanf(line,"# %s et al.",name); But I can only get the first token (which, in this case, is "John").
