i have function removes occurrences of sub-string c++ string. want insert spaces before or after removing every sub-string. function if given below:

    void removesubstrs(string& s, string& p) {     string::size_type n = p.length();     (string::size_type = s.find(p);         != string::npos;         = s.find(p))         s.erase(i, n); } 

for example if input "azazblackazazberryaz", want output "black berry"....

if want this:

assume "-" space
input: "azazblackazazberryaz" , "az"
output: "--black--berry-"

then, may you:

  void removesubstrs(string& s, string& p) {     string::size_type n = p.length();     (string::size_type = s.find(p); != string::npos; = s.find(p))     {         s.replace(i, n, 1, ' ');         //or         //s.erase(i, n);         //s.inset(i, ' '); //add line     } }
