Removing punctuations from a given string
Given a string, remove the punctuation from the string if the given character is a punctuation character as classified by the current C locale. The default C locale classifies these characters as punctuation:
!"#$%&'()*+,-./:;?@[\]^_`{|}~
Examples:
Input : %welcome' to @geeksforgeek<s Output : welcome to geeksforgeeks Input : Hello!!!, he said ---and went. Output : Hello he said and went
A loop is designed that goes through a list composed of the characters and punctuations of that string, removes the punctuation and then joins them.
C++
// CPP program to remove punctuation from a given string #include <iostream> using namespace std; int main() { // input string std::string str = "Welcome???@@##$ to#$% Geeks%$^for$%^&Geeks"; for (int i = 0, len = str.size(); i < len; i++) { // check whether parsing character is punctuation or not if (ispunct(str[i])) { str.erase(i--, 1); len = str.size(); } } // print string without punctuation std::cout << str; return 0; } |
