Hello,

I need a little help . I want a program whose output is :


Enter a positive integer : 5

1
22
333
4444
55555


I know its gotta be done using for loops but can anyone help?

I have made so far:

#include<iostream.h>
#include<conio.h>
void main(void)
{
int x;
cout<<"Enter a positive integer ?";
cin>>x;
for ( int i=1; i<=x; i++ )
{
cout<<i<<endl;
}
getch();
}

you need to write a nested for loop
which means a loop inside another loop

for(){
for(){
}
}

#include<iostream.h>
#include<conio.h>
void main(void)
{
int x;
cout<<"Enter a positive integer ?";
cin>>x;
for ( int i=1; i<=x; i++ )
{
for(int ii = 1; ii < i; ii++)
{
cout<<i<<endl;
}
}
getch();
}

Thanks Chris . It worked , Just had to make a little modification to your code:

#include<iostream.h>
#include<conio.h>
void main(void)
{
int x;
cout<<"Enter a positive integer ?";
cin>>x;
for ( int i=1; i<=x; i++ )
{
cout<<endl;
for(int ii = 1; ii <= i; ii++)
{
cout<<i;
}
}
getch();
}


----


added cout endl in first loop to make it go to next line , and in second loop made it ii<= instead of ii< as it missed 1 otherwise .

Thanks for your help
