how to ignore space in string program in c++

Answer 1

For both space and punctuation

#include <iostream>
using namespace std;

int main() {
string text = "this. is my string. it's here.";
for (int i = 0, len = text.size(); i < len; i++){
if (!isalnum(text[i])){
text.erase(i--, 1);
len = text.size();
}
}
cout << text;
return 0;
}

Answer 2

For only spaces use

#include <iostream>
using namespace std;

int main() {
string input = "this. is my string. it's here.";
for (int i = input.length()-1; i >= 0;--i){
if(input[i] == ' ')
input.erase(i, 1);
}
cout << input;
return 0;
}

Answer 3

You can use setfill() method to set character to empty spaces like use
setfill('');
it will remove all spaces. You have to include a header file called
#include<iomanip>
Moreover can you give me a sample program. Then I can help you better.
