What's wrong with this code?!!

Question

#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;
}

Answer 1

@Lukman wat result do u want

Answer 2

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

Answer 3

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

Answer 4

Lukman u can combine as many as u want in most languages

Answer 5

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;
}

Answer 6

@Yerucham just the same!!!

Answer 7

Yep
that's what I'm talking about

Answer 8

I was just trying the nested if

Answer 9

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

Answer 10

@Tobias Hallmans but can't you see it. i've wrote:
if (age==18) {
cout <<"you are adult":
}

Answer 11

@Ace so can I write
else (Statement) {
cout <<"......";
}

Answer 12

So helpful! thank you so much 😊☺☺

Answer 13

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

Answer 14

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".

Answer 15

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

18 > 18 is false

Answer 16

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#)

Answer 17

Don’t know
