i want to find the position of the first string in input.txt that matches a regex
// Input.txt

Hello everyone, i am John It is rainy today

temp.resize(500);

I am trying to get the position of the matches of "Un" in string "Unseen University" in c++ code using STL regex. How can I do this.
i.e. I have following:
std::vector<std::cmatch*>* matches = new std::vector<std::cmatch*>*;
intMyReturnVal = regex("Unseen University", "Un", matches);
I can access a match by
matches->at(i)
and get an Iterator to the beginning of the match by
matches->at(i)->begin()
How can I get the relative position of the match within the entire target string (i.e. "Unseen University", where, in this case, the positions should be 0 and 7)??
I'm creating a program that takes user input in the form of a string and tests to see if it matches a word. Each correct word will increase their score by one. Here is a portion of the code that is not working.
...
else if(s == 32) {
if(!currentLetter.empty()) {
currentLetter.erase(currentLetter.length() - 2, currentLetter.length() - 1);
} if(currentLetter.compare(oWord) == 0) {
[Code] .....
To me, this looks like it should do a very simple task as intended-take a String, compare it to another, and reset the word if they match or output incorrect if not. But, I'm not sure if there is some quirk in C++ with Strings, because this code always outputs Incorrect. Please try again. and the score never increases. I also tested this by literally setting the strings equal in the code, which still resulted in it not doing what it's supposed to.
I need to find position of certain character in string, so i made a function but it doesn't do what i thought it would.
Consider this string:
std::string line = "<foo> <foo> <foo> <foo> <foo>"
I need to find position of a third '>' character so i can get:
std::string other = "<foo> <foo> <foo>";
This is my function that fails:
std::size_t find_third(const std::string& line) {
std::size_t pos = 0u;
for(std::size_t i = 0; i < 3u; ++i) {
std::string tmp = line.substr(pos);
pos = tmp.find_first_of('>');
} return pos;
}
I've been trying to do a RegEx, but I just can't seem to find the solution for it.
Do the following to find Test:
Test55: Will be allowed
TestABC: Will NOT be allowed
Basically, if Test is followed immediately by anything else other than a case-insensitive letter (not [a-zA-Z]), then it will pass.
I have a question about finding the length of first sentence in an input string.
For example, let the input string be: dream in code. community learning
The length of first sentence is 13 (blanks are included). My question is how to create conditions for multiple punctuation signs (!,?)? If while loop goes like:
while((str[i]!='.')||(str[i]!='!')||(str[i]!='?'))
it gives me an error for infinite loop.
Code:
#include<stdio.h>
int main() {
char str[100];int i=0,br=0;
printf("enter a string:");
gets(str);
[Code] ....
In the MSDN, it gives an example using Regex.Matches method:
using System;
using System.Text.RegularExpressions;
public class Example {
public static void Main() {
string pattern = "a*";
string input = "abaabb";
foreach (Match m in Regex.Matches(input, pattern))
Console.WriteLine("'{0}' found at index {1}.",
m.Value, m.Index);
[code]......
I am wondering if string input was an array of strings instead, how would I use Regex.Matches?
What I was thinking about doing is having the input array set to ToString(), input.ToString(), but that doesn't seem to work.
I want to get the iterator position after to use find if:
std::list<Texture*>::iterator result = find_if(
texturelist.begin(),
texturelist.end(),
std::bind2nd<CompareTEX>(CompareTEX(),n_tex));
if (result != texturelist.end()) {
return // position result
}
I have the the following two strings:
D 1069 Dresden - Neustadt
01069 Dresden - Neustadt
I want to splitt the string and the result should be in both cases:
1069
Dresden - Neustadt
How could i do this with regular expression?
I try to find charecter position but evey time i run my program it give me 0 position why ? Why in my getChar function give me warning statement with no effect i can not understand this warning where is my mistake.
Code:
void getChar(const char* str){
int lenStr = strlen(str);
int i = 0;
int posCharecter = 0;
printf(" %s has %d charecters length
",str,lenStr);

What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.
My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?
find inserted numbers, let say 10 numbers and find the largest and second largest number with their position in an array?

Very 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]
View 1 Replies View RelatedI have this array (assume sorted) and i need to find out the closest upper value for any input int. Example:
Code:

int compareints (const void * a, const void * b) {

I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}
