Hello. I hope you guys are having a good day.
I am on the vectors review and I decided that I would create a program to test my coding skills, but I encountered an error that’s telling me that elseif is some sort of variable that has not been defined.
I don’t know what to do.
I would appreciate your help on this topic.
Here’s a link:

Here’s the code:
#include
#include
int main() {
std::vectorNumbers = {0, 0, 0};
int storage = 0;
std::cout <<“Welcome to the even and odd numbers calculator\n”;
std::cout <<“Please enter first number (single digit only)\n”;
std::cin >> storage;
Numbers.push_back(storage);
std::cout <<“Next number please\n”;
std::cin >> storage;
Numbers.push_back(storage);
std::cout <<“And anoter one\n”;
std::cin >> storage;
Numbers.push_back(storage);
std::cout <<“Anoter one\n”;
std::cin >> storage;
Numbers.push_back(storage);
std::cout <<“And anoter one\n”;
std::cin >> storage;
Numbers.push_back(storage);
std::cout <<“Thank you, Here is your anser.\n”;
double even = 0;
double odd = 0;
for (int i = 0; i < Numbers.size(); i++) {
if (Numbers[i] == 1) {
odd = odd + Numbers[i];
}
elseif (Numbers[i] == 2) {
even = even + Numbers[i];
}
elseif (Numbers[i] == 3) {
odd = odd + Numbers[i];
}
elseif (Numbers[i] == 4) {
even = even + Numbers[i];
}
elseif (Numbers[i] == 5) {
odd = odd + Numbers[i];
}
elseif (Numbers[i] == 6) {
even = even + Numbers[i];
}
elseif (Numbers[i] == 7) {
odd = odd + Numbers[i];
}
elseif (Numbers[i] == 8) {
even = even + Numbers[i];
}
elseif (Numbers[i] == 9) {
odd = odd + Numbers[i];
}
}
std::cout <<“Sum of Even numbers\n”;
std::cout << even<<"\n";
std::cout <<“Sum of Odd numbers\n”;
std::cout << odd<<"\n";
std::cout <<“Thankyou for using the Even and Odd Numbers Calculator\n”;
}
Here’s a screenshot:
Sorry it is not showing “include iostream” and “include vector”.
Thanks for your help and support.
