what is wrong in this code playground is showing it wrong

Question

#include <iostream.h>
#include <conio.h>
void main()
{
clrscr();
for(int i=1;i<=5;i++)

cout <<"\n";
for(int j=1;j<=i;j++)

cout<<"*";

}

Answer 1

- Use <iostream> instead of <iostream.h>
- no need for conio.h/clrscr()
- Put "using namespace std" to not have to put std:: in front of std elements (like std::cout)
- main() must return an int
- put brackets { } to nest the second for loop inside the first one.

#include <iostream>
using namespace std;

int main() {
for(int i=1;i<=5;i++) {
for(int j=1;j<=i;j++)
cout<<"*";
cout <<"\n";
}
return 0;
}

Answer 2

Use #include<iostream> in the first line .This is because using .h in including files is an old method that's outdated in most ide and terminals nowadays .

Answer 3

The Program is right most of the ide dont support #include<iostream.h>
only in Turbo C the #include<iostream.h> is accepted ....
ide like code block , and dev c++ support only this format of header file syntax
#include<iostream> . No .h should be included
