Question

how to delete first word and last word in a string of user input ex: int main) string fullname; cout << "Enter Full Name ex: Rob John Smith" << endl; cin >fullname; //Some code that will delete the first and /last name to get middle name cout < "Your middle name is:" midname;

Answer 1

C++ CODE:

Note: Use the getline function to take input otherwise it will not take full string because it inputs string till first space.

#include<iostream>
#include<string>
using namespace std;
int main()
{
string fullname;
cout<<"Enter Full Name ex: Rob John Smith: "<<endl;
getline(cin,fullname);
string midname="";
int j=-1;
for(int i=0;i<fullname.size();i++)
{
if(fullname[i]==' ')
{
if(j==-1)
j=i;
else
{
midname=fullname.substr(j,i-j+1);
break;
}
}
}
cout<<"Your middle name is:"<<midname;
return 0;
}

Output:
