Write a program in C++ to print a pattern of right angle triangle with a number that will repeat a number in the row by using the constructor and destructor.
C++ Program to print a pattern of the right-angle triangle using Constructor
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | #include<iostream> using namespace std; class T4Tutorials { protected : int i,j,n,r; public : T4Tutorials() { cout<<"Enter no of rows : "; cin>>n; for(i=1 ; i<=n ; i++) { for(j=1 ; j<=i ; j++) { cout<<i; } cout<<endl; } } }; int main() { T4Tutorials a; } |
Output
