How can I replace the double space into single space using C++
ex:
"1 2 3 4 5" => "1 2 3 4 5"
this is what I`ve done till now:
int _tmain(int argc, _TCHAR* argv[])
{
string line;
ifstream myfile(myFile);
if(myfile.is_open())
{
cout<<"File Opened ...\n";
while(myfile.good())
{
getline(myfile,line);
splitLine(line);
//cout<<line<<endl;
}
}
else
cout<<"File Not Found ...\n";
myfile.close();
return 0;
}
void splitLine(string line)
{
int loc;
cout<<line<<endl;
while(loc = line.find(" "))
{
cout<开发者_运维技巧<loc<<endl;
}
}
In while loop of splitLines code, use this code.
while((loc = line.find(" ")) != std::string::npos) //Two spaces here
{
line.replace(loc,2," "); //Single space in quotes
}
cout << line << endl;
Thats it. I haven't tried it out, let me know if it works.
And as fred pointed out, use pass by reference in splitLines function. The above solution is sub-normal and is O(n^2) complexity. This one is better.
int loc = -1;
while((loc = line.find(" ",loc+1)) != std::string::npos) //Two spaces here
{
line.replace(loc,2," "); //Single space in quotes
}
cout << line << endl;
