Answer 1

Sound more like a demand than a question. lol :D

Anyways, if it's a question, you can do that with a simple loop.

int main() {
string firstString[1] = "abcd";
string secondString[1] = "xyz";
string thirdString[1] = "";

for(int i = 0; i < firstString[0].length(); ++i) {
thirdString[0] += firstString[0].at(i);
if(i < secondString[0].length()) {
thirdString[0] += secondString[0].at(i);
}
}

cout << thirdString[0];

return 0;
}

However, I did it like that because it's what you asked. Using arrays in this scenario doesn't make much sense since you're only utilizing 1 element in all of them. You can easily do this with just simple string variables and not arrays.

#include <iostream>
using namespace std;
#include <string>

int main() {
string firstString = "abcd";
string secondString = "xyz";
string thirdString = "";

for(int i = 0; i < firstString.length(); ++i) {
thirdString += firstString.at(i);
if(i < secondString.length()) {
thirdString += secondString.at(i);
}
}

cout << thirdString;

return 0;
}
