What is wrong with that code please help me I can't figure out

Question

Answer 1

don't put return 0; on the beginning. it will cause main() to exit immediately.

if conditions are enclosed in parenthesis

if (points<20)

#include <iostream>
using namespace std;

int main() {
// return 0; ❌ wrong
int points;
cin>>points;
cout << points;
if (points<20) { ✅ use ( )
cout << "Tu as rouge."<<endl;
}
return 0; ✅ put return 0; here
}

Answer 2

Bhushan kale keep your language clean on Sololearn. Personal attacks are unacceptable and will get your account banned.

Answer 3

There are two problems with your code.
The `return 0;` statement returns a value from the function(in this case, main()) and stops the function. Also, you need to wrap your conditions inside these brackets– ( )

Here is the fixed, working code
```
#include <iostream>
using namespace std;

int main() {
// remove return 0 from here
int points;
cin>>points;
cout << points;
if (points<20) { // wrap your condition in parenthesis
cout << "Tu as rouge."<<endl;
}
return 0; // putting it here ensures all code runs before termination
}
```
You might want to use `cout <<points << endl;` for better formatting

Answer 4

As the code evolves, errors evolve too. Keep trying! Errors are a constant companion to developing code - even for professional programmers.

Though you corrected the above problems, new changes added another. The latest problem is that the less-than-or-equal comparison operator is mistyped. It should be <=, not =<.

Answer 5

other than being written the wrong way, (most people would put the >= on the left and the <= on the right of &&), your conditions are mostly inverted.

also, else does not accept any condition.

#include <iostream>
using namespace std;

int main() {
int points;
cin>>points;
cout <<points <<" points.";
if(points>=0 && points<=19) {
cout << "Tu as rouge."<<endl;
}
else if (points>=20 && points<=39){
cout << "Tu as jaune."<<endl;
}
else if (points>=40 && points<=59){
cout << "Tu as vert pale."<<endl;
}
else if (points >=60 && points<=79){
cout << "Tu as vert."<<endl;
}
else if (points>=80 && points<=99){
cout << "Tu as vert +."<<endl;
}
else{
cout << "Tu ment on peut pas avoir plus de 100 points."<<endl;
}

return 0;}

Answer 6

Thanks

Answer 7

U may also use switch statement that is easy to understand and write

Answer 8

The code has minor error you need to write return 0; line below if statement and in if statement you need to add common brackets inside the condition

Like this below

#include <iostream>
using namespace std;

int main() {
int points;
cin>>points;
cout << points;
if (points<20) {
cout << "Tu as rouge."<<endl;
}
return 0;
}

Answer 9

Ok thanks guys

Answer 10

Please I got another problem and I don't understand it

Answer 11

Alban you can give range in switch statement too so less error. Check out the link below for understanding how it works

Answer 12

Ok I will do it

Answer 13

What did he said ?

Answer 14

No because I have to say case 1,case 2 and do it untik I reach 100 so it is way more dificult to read and I will make more mistakes

Answer 15

Aysha, Alban

while using range in switch-case works here in Sololearn, you should be aware that it's a compiler dependent feature.

it does not work for non-GCC compilers, so you should test it and be aware that it's a GCC extension and might not work if your code happens to be compiled with other compilers...

Answer 16

Ok
