Write a C++ program to print the required output using for loop.

Below is the program to prepare required output. Please include iostream.h and conio.h header files before declaration of class.
//PROGRAM TO PREPARE REQUIRED OUTPUT USING FOR LOOP.
#include
#include
class sample
{
private:
int n,r,c,d;
public:
void get(int t)
{
n=t;
d=1;
}
void display(void)
{
cout<<"\nRequired output for "< for(r=1;r<=n;r++)
{
d=1;
for(c=1;c<=r;c++)
{
cout< d++;
}
cout<<"\n";
}
}
};
void main(void)
{
class sample s;
clrscr();
int x;
cout<<"\nEnter number of lines you needed\n";
cin>>x;
s.get(x);
s.display();
getch();
}

Break and Continue statement is basically use for the change the flow of a program. Below is detail description about these both statement:

Break Statement -: Break statement is use in that case when you want to stop the further execution of the program. It is use with conditional statement(if..else). Below is the small exmple of Break statement.
#include
int main(void) {
// your code goes here
for(int i = 1; i <= 10; i++)
{
if(i > 5)
{
break;
}
else
{
printf("%d\n", i);
}
}
return 0;
}
Note: As you can see in the above example, if i greater than 5 only in that case it will terminate the program but if i is 5 or less than 5 then it will process the code.

Continue Statement -: Continue statement is use in that case when you want to skip some statement in program.It is also use with conditional statement(if..else). Below is the small exmple of Continue statement.
#include

int main(void) {
// your code goes here
for(int i = 1; i <= 10; i++)
{
if(i == 5 || i == 7)
{
continue;
}
else
{
printf("%d\n", i);
}
}
return 0;
}
Note: As you can see in the above example, if i is 5 or 7 then this program skip these both from output and continue with next iterations.


Below is the program for print the required output:

#include
using namespace std;
int main() {
// your code goes here
for(int i = 1; i <= 5; i++)
{
for(int j = 1; j <= i; j++)
{
cout< }
cout<<"\n";
}
return 0;
}
