Question

Plz i need help i'm beginner ☺️

Answer 1

#include<iostream>
using name space std;
int main()
{
int n;
cin>>n; // n==5
for(int i=1;i<n;i++)
{
for(int j=1;j<=i;j++)
{
cout<<j<<" ";
}
cout<<endl;
}
return 0;
}

Answer 2

C++ with single loop:

#include <iostream>
#include <string>
#include <sstream>
using namespace std;

int main() {
string s = "";
for (int x=1; x<=5; x++) {
stringstream ss;
ss << s << x;
ss >> s;
cout << s << endl;
}
return 0;
}

Answer 3

I will try to write code now

Answer 4

Do you know the concept of loops or pattern ?

If no then,
If you see the number of columns=number of rows
And make a counter which increases every column and turns 0 when a row is finished

Try to understand the logic
Even programming language is changed logic remain the same right

In C printf
In CPP cout
In JAVA System.out.println(””);
In PYTHON print()
Method name is changing but logic will be same
