Let’s begin with defining a class in the C++ object-oriented program.
Program
Write a program in C to display such a pattern for n number of rows using a number which will start with the number 1 and the first and the last number of each row will be 1. The pattern is as follows:
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 26 27 28 29 30 31 32 33 34 | #include<iostream> using namespace std; class T4Tutorials { protected: int i,j,k,l,n; public: int show() { cout<<"num of rows :"; cin>>n; for(i=1;i<=n;i++) { for(l=1;l<=n-i;l++) { cout<<" "; } for(j=1;j<=i;j++) { cout<<j; } for(k=i-1;k>=1;k--) { cout<<k; } cout<<endl; } } }; int main() { T4Tutorials obj; obj.show(); } |
