Question

c++ Language

Fix this code to have it concatenate two strings st1 and st2 and put the result in st3 with a space separator. it has to be done using array representation of strings

#include <iostream>
using namespace std;

#include <string>


int main()
{
string st1,st2, st3;
int c = 0, i =0;
  
cout << "Enter a string: ";
cin >> st1;
cout << "Enter another string: ";
cin >> st2;
  
while (st1[c] != '\0'){
st3[c] = st1[c];
st3[c+1] = '\0';
cout << endl << st1[c] << " " << st3[c];
cout << endl << "current valuse of st3 is: " << st3;
c++;
}
  
st3[c] = ' ';
c++;
while (st2[i] != '\0'){
st3[c] = st2[i];
c++;
i++;
}
  
st3[c] = '\0';
  
cout << st3;
  

return 0;
}

while (st1[c] != '\0'){
st3[c] = st1[c];
cout << endl << st1[c] << " " << st3[c]<<"\n";
c++;
}
st3[c+1] = '\0';
st3[c] = ' ';
c++;
while (st2[i] != '\0'){
st3[c] = st2[i];
c++;
i++;
}
  
st3[c] = '\0';
  
while(st3[e]!='\0'){
cout<<st3[e];
e++;
}

cout<<"\n";

return 0;
