Remove space from input

[eli m]

Hi, I have a program where the input involves space sometimes and i want to remove the spaces from the input. For example: if they type in hello world, then it would receive helloworld. How would i do this? Thanks in advance.

You 'find_first_of' space and then 'erase' it until there are none.

Just use >> on strings, and then concatenate them.

If you read strings from your input stream using operator>> the

whitespace between the strings is not included in the strings.



If you then join the strings together you will have removed the whitespace.



"abc def ghi" becomes the three strings "abc" "def" "ghi" which

when concatenated are "abcdefghi"

Can you provide an example please? Sorry, i am a noob.

std::string word;
while ( input >> word ) {
output << word;
}

will copy the input to the output, removing all spaces. Or

std::string results;
std::string word;
while ( input >> word ) {
results += word;
}

will result in the input, without spaces, in results.
