C++ Exercises: Display Pascal's triangle like pyramid
C++ For Loop: Exercise-45 with Solution
Write a program in C++ to display Pascal's triangle like pyramid.
Sample Solution:-
C++ Code :
#include <iostream>
using namespace std;
int main()
{
int row,c=1,blk,i,j;
cout << "\n\n Display the Pascal's triangle:\n";
cout << "-----------------------------------\n";
cout << " Input number of rows: ";
cin >> row;
for(i=0;i<row;i++)
{
for(blk=1;blk<=row-i;blk++)
cout<<" ";
for(j=0;j<=i;j++)
{
if (j==0||i==0)
c=1;
else
c=c*(i-j+1)/j;
cout<<c<<" ";
}
cout<<endl;
}
}
Sample Output:
Display the Pascal's triangle: ----------------------------------- Input number of rows: 5 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1
