| Previous | Home | Next |
In this example we are going to print binary triangle using C. We are printing 1 in first line ,0 1 in second line ,1 0 1 in third line ,0 1 0 1 in forth line and so on.
/* 1
0 1
1 0 1
0 1 0 1
1 0 1 0 1 */
#include<stdio.h>
#include<conio.h>
void main()
{
int i,j,n;
clrscr();
printf("Enter a number\t");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
for(j=1;j<=i;j++)
{
if(i%2==0)
{
if(j%2==0)
printf("1");
else
printf("0");
}
else
{
if(j%2==0)
printf("0");
else
printf("1");
}
}
printf("\n");
}
getch();
