# Print binary number in c – C program to print binary numbers right triangle pyramid pattern

• Write a C program to print right triangle of binary number.

For a binary number right triangle of 6 rows, program’s output should be:

Algorithm to print triangle pattern of binary numbers
Print binary number in c: This program is similar to right triangle star pattern. The only difference is instead of printing star characters we will print binary digits.

• Take the number of rows(N) of right triangle as input from user using scanf function.
• Number of integers in Kth row is always K+1.
• We will use two for loops to print right triangle of binary numbers.
• Outer for loop will iterate N time(from 1 = 0 to N-1). Each iteration of outer loop will print one row of the pattern.
• Inside inner loop will toggle binary digits and print it. Each iteration of inner loop for Kth row will print K+1 alternating 0 and 1.

Here is the matrix representation of above mentioned pattern. The row numbers are represented by i whereas column numbers are represented by j.

### C program to print right triangle pattern having same number in a row

#include<stdio.h>

int main() {
int i, j, rows;
int count = 1;

printf("Enter the number of rows\n");
scanf("%d", &rows);

for (i = 0; i < rows; i++) {
for (j = 0; j <= i; j++) {
printf("%d ", count);
count = !count;
}
count = i % 2;
printf("\n");
}
return(0);
}

Output

Enter the number of rows
5
1
0 1
1 0 1
0 1 0 1
1 0 1 0 1
