question on whitespace in string

[gdarian216]

I am writing a program that takes input from a user and the program corrects the whitespace and capitalization errors. I have written the part to get the input from the user and stores it in an string with a getline function. My problem is I am tring to figure out a way to check and remove whitespace if anyone can help

thanks

#include <string>
#include <iostream>
using namespace std;
 
int main() {
 
        cout << "enter sentence and hit enter";
        string  s1;
        getline(cin,s1);

this is how i am getting the input in.

are you looking to get rid of the whitespace before the string or throughout?
for case one you could just add a cin >> fistword; then after the getline st = firstword + st1;
for the second case i'm not too sure....

Depends on what you are trying to. You could go thru your string examining each character for correct capitalisation and removing excess whitespace

the C++ <string> class has methods which enable you to iterate thru the contents of a string, repace characters, erase characters, etc. see

I have had success deleting all whitespace from a given string using the following:

1 #include <iostream>
2
3 void DeleteWS(std::string& x)
4 {
5 for(unsigned int i = 0; i <= x.length(); i++)
6 {
7 if(x[i] == ' ')
8 {
9 x.erase(i, 1);
10 }
11 }
12 }
13 int main()
14 {
15 std::string myString;
16 std::cout << "String: ";
17 getline(std::cin, myString);
18 DeleteWS(myString);
19
20 std::cout << myString << std::endl;
21 }

If anybody notices anything inherently wrong with this code, please let me know.
