What's wrong with this code?!!

#include <iostream> using namespace std; int main() { int age=18; if (age > 18){ if (age==18) { if (age == 20) { cout<<"you are adult"; } } } if (age > 0) { if (age < 18 ) { cout<<"you are a child" } } else { cout<<"something went wrong"; } return 0; }

If u want "you are an adult" to print, that wont work because first: age is not > 18 and age is not = 20

Try this #include <iostream> using namespace std; int main() { int age=18; if (age > 18){ { if (age==18) { if (age == 20) { cout<<"you are adult"; } } } if (age > 0) { if (age < 18 ) { cout<<"you are a child" } } } else { cout<<"something went wrong"; } return 0; } EDIT: #include <iostream> using namespace std; int main() { int age=18; if (age >= 18){ if (age==18) { //NOT NECESSARY if (age == 20) { cout<<"you are adult"; } } // } if (age > 0) { if (age < 18 ) { cout<<"you are a child"; } } else { cout<<"something went wrong"; } return 0; }

So, in C# can you inculde as many && as you want in the if statement

You ask whether age is strictly greater then 18. If so, you ask if it's equal to 18. That can never happen here.

You're missing a semicolon here: cout<<"you are a child"; <-- here The output as the code is currently written will be nothing not "something went wrong".

that part of the code is never reached as it will be skipped by the surrounding if statement. 18 > 18 is false

why do you not use logical "and(&&) " and "or(||)". for example : if (age>0 && age <18) . or in c++ it does not work( i learn c#)
