words

问题 I'm attempting to search for content between 2 whole words using a regular expression. For example: all the girls went to the mall in town. In the above string I want to find the content between the word all and to : (?<=all).*?(?=to)/g However, it's finding two matches since the expression is not instructed to search between whole words only: " the girls went " //between all and to " in " //between m(all) and (to)wn I had thought to add spaces in the expression, like this: (?<= all ).*?(?=

问题 I have an ASCII text file. I want to generate a list of all "words" from that file using one or more Ubuntu commands. A word is defined as an alpha-num sequence between delimiters.

问题 I'm a beginner and I've been going through a book on C++, and I'm on a chapter on functions. I wrote one to reverse a string, return a copy of it to main and output it. string reverseInput(string input); int main() { string input="Test string"; //cin>>input; cout<<reverseInput(input); return 0; } string reverseInput(string input) { string reverse=input; int count=input.length(); for(int i=input.length(), j=0; i>=0; i--, j++){ reverse[j]=input[i-1]; } return reverse; } The above seems to work.
