This is a way to remove all spaces in a string:
std::string removeSpace(const std::string& str){
std::string strToRemove = " ";
std::string ret(str);
size_t pos = ret.find(strToRemove);
whilt(pos != std::string::npos){
ret = ret.replace(pos, strToRemove.length(), "");
pos = ret.find(strToRemove);
}
return ret;
}
std::string source = "Hello World";
source = removeSpace(source); // source -> "HelloWorld"
You can also use the same way to replace or remove other charactors:
std::string replace(const std::string& strToConvert,
const std::string& strToReplace,
const std::string& strToReplaceBy){
std::string ret(strToConvert);
size_t pos = ret.find(strToReplace);
while(pos != std::string::npos){
ret = ret.replace(pos, strToReplace.length(), strToReplaceBy);
pos = ret.find(strToReplace);
}
return ret;
}
std::string source = "Hello C++";
source = replace(source, "+", "p"); // source -> "Hello Cpp"
