Question

string hello="hello";
int i=hello.size();
for(int j=0;j<i;j++){
match[j]=hello[j];
}
cout<<match;

Answer 1

int main() {
string match = "";
string hello = "hello";
int i = hello.size();
for(int j =0;j<i;j++) {
match = match + hello[j];
}
std::cout<<match;
std::cout<<hello;
}

you cannot use match[j] because match is not array, and you are not fill it with any string, maybe that is :D, the code is tested , and its work.
