Answer 1

Will there are so many errors.. I have commented what changes I have done into below code :

#include <iostream>
using namespace std;

// Age Evaluater

int main() {
int age;
cin >> age; // it should not be << operator with cin
//return 0;
//if return is there, next code doesnot get executed

if (age <= 17)// braket for condition
{
printf("Sorry, you need to be 18 years or older");//1.semicolon for statement end 2. its string not character...so, ' ' is replaced with "" 3. print is not there..printf is used
}
else if (age >= 18) //bracket and elif should be else if

{
printf("Welcome! Sign up or log in here: ");// semicolon and "" instead of '' Nd printf
}
return 0;//added here
}// added here

Feel free to ask if you have any questions in updated code

Answer 2

Will ..np... different languages have different syntax..u will be familiar to it soon... happy learning..

Answer 3

Will refer below changes to be done:

1. entry point is int main()...so, it must have it... post int Main () , your entire code should be enclosed within {}... so, add these two it...

2. cout << endl should be there... so, instead of +endl, do it like << endl in both if and else..

feel free to ask for any clarification

Answer 4

perfect now Will ...it works fine...

just do mention return 0 ; as second last line just before }..

return 0 indicate that your entire code worked fine and there is no error fro m code execution.people returns negative values to indicate some failure of code like file access etc

Answer 5

Answer 6
