[Code]....
The code above loops through a string and for each character checks to see if it is a lower case character, then checks to see if it an upper case. It then removes it if it is. Leaving only the numbers.
However, it reuses the same string the entire time, never updating the string so it always finds the same (first) character.
I have made a new Windows Phone App and I would like there to be two versions: one without ads (79p) and one with ads (free). I have sorted out everything expect one issue. I collapse the advert if the app is in the full version but the rest of the page stays the same. How do I move the 'content panel' after the advert is collapsed?
I want to remove some character in my file. too i want to replace some char to another. I know the easiest way for this job is we write final text in file. i mean we first produce sightly text then write it in file . I don't want use of temporary string.
The goal is to merge two files of names, sort them and remove duplicates.I've managed to merge the two files into a single char array and sort them with a function so they are alphabetical.I'm having problems removing the duplicate entries from the array. Here is my code:
how can I read some strings that contains spaces and put them in a vector of strings, using the push_back() function?
I have a collection of functions, for example: [multiply_by_forty two, add_by_five]. All I want to do is to store the strings like: multiply_by, add_by in a vector of strings, and the arguments:forty two, five etc in another vector of strings, but with spaces. The function convert() converts written numbers to numbers (for ex the output of covert("forty two")is 42;)
I have a problem, caught the last line of a file and do the division of the same variables in, date, time and value, but the file contains excess spaces in all lines and the date is coming with cuts, example 24/4/2014 appears 4/4/2014. How can I remove the space in the string without affecting the division of the line?
if (file) { std::string line = getLastLine(file); std::istringstream iss(line); getline(iss, date, ' '); getline(iss, time, ' '); getline(iss, t); //variavel para temperatura em string } else { std::cout << "error file ";
I am writing a parse system, and I want to go in and check a string for multiple Ks to be exact a K at the beginning and one at the end, if it does have a K at the end of the string I want to remove that K. I don't have an exact size of my string. I know how to remove the last K but not how to check the string for the multiple Ks.
This is what I have:
if (poNumber.Contains("K...K")) poNumber.Remove(poNumber.Length - 1,1);
I know that the first part will not work the way I want it to.
I have the codes for such a problem where, to create a program that counts how many times the second string appears on the first string. Yes it counts if you put 1 letter only, but if you put 2, it is an error. As an example. If the first string is Harry Partear, and the second string is ar, it must count as 3. Here's the code:
Code:
#include <iostream> #include <conio.h> using namespace std; int main ()
I'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);
Above is the code I have tried using and it stores data under *chr, it however only stores one letter rather than the entire word like for example string.
This sends the buffer to a LIN modem. My question is: can this be done better. If I have a astring of hex numbers like "09 98 88 55 42 FF 00 00 FF BD 89". How could I send this without manually makng a char with hex numbers?
