What happens when you attempt to compile and run the following code? #include <iostream> #include ‹set> #include < vector><br />
using namespace std;<br />
int main(<br />
int t[] = ( 3, 4, 2, 1, 6, 5, 7, 9, 8, 0);<br />

range = s1.equal_range(6);<br />
while (range. first!= range.second) {<br />
cout‹‹*range.first‹<""; range.first++;<br />

What will happen when you attempt to compile and run the code below, assuming that you enter the following sequence: one two three‹enter»? #include <iostream> #include ‹string><br />
using namespace std;<br />
int main ()<br />
string a;<br />
cin>a;<br />
cout‹<a<<endl;<br />
return O;<br />
<br />
Program will output:
