hello i want to write code for this
in my opinion pascal triangle is:-
1
1 1
1 2 1
1 3 3 1

u wil find this by following prog:-
/*Program to Calculate the Pascal triangle */
#include<stdio.h>
int main()
{
int a[20][20];
int i,j,c,n,k;
printf("Enter how many lines do you want");
scanf("%d",&n);
a[1][1]=1;
a[2][1]=1;a[2][2]=1;
for(i=1;i<=n;i++)
{ for(j=1;j<=n-i;j++)
printf(" ");
if(i<3)
{
for(k=1;k<=i;k++)
{
printf("%d ",a[i][k]);
}
printf("\n");
}
else
{
a[i][1]=1;
printf("%d ",a[i][1]);
j=2;c=3;
while(j<i)
{
a[i][j]=a[i-1][c-2]+a[i-1][c-1];
printf("%d ",a[i][j]);
c=c+1;
j=j+1;
}
a[i][j]=1;
printf("%d\n ",a[i][j]);
}
}
getche();
}
