program :To generate pascal triangle
Source Code :
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 | #include<iostream.h> #include<conio.h> #include<iomanip.h> void main() { int i,j,k,n; clrscr(); cout<<"Enter no. of rows: "; cin>>n; cout<<"The pascal triangle is:"<<endl; for(i=0;i<n;i++) { for(j=i;j<n-1;j++) cout<<" "; int binom=1; for(k=0;k<=i;k++) { if(i==0||k==0) cout<<" "<<binom; else { binom=binom*(i-k+1)/k; cout<<" "<<binom; } } cout<<"\n\n"; } getch(); } |
/* Output:
Enter no. of rows: 5
The pascal triangle is:
1 2 3 4 5 6 7 8 9 | 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 |
