In this tutorial, i am going to show you how to right triangle of numbers in sine wave pattern with the help of for loop and while loop in c programs.
All C Program to Print Right Triangle of Numbers in Sine Wave Pattern
- C Program to Print Right Triangle of Numbers in Sine Wave Pattern using For Loop
- C Program to Print Right Triangle of Numbers in Sine Wave Pattern using While Loop
C Program to Print Right Triangle of Numbers in Sine Wave Pattern using For Loop
#include <stdio.h>
int main()
{
int rows;
printf("Enter Right Traingle of Numbers in Sine Wave Rows = ");
scanf("%d", &rows);
printf("Right Traingle of Numbers in Sine Wave Pattern\n");
for (int i = 0; i < rows; i++)
{
for (int j = 0; j <= i; j++)
{
if (j % 2 == 0)
{
printf("%d ", 1 + j * rows - (j - 1) * j / 2 + i - j);
}
else
{
printf("%d ", 1 + j * rows - (j - 1) * j / 2 + rows - i - 1);
}
}
printf("\n");
}
}
The result of the above c program; is as follows:
Enter Right Traingle of Numbers in Sine Wave Rows = 5 Right Traingle of Numbers in Sine Wave Pattern 1 2 9 3 8 10 4 7 11 14 5 6 12 13 15
C Program to Print Right Triangle of Numbers in Sine Wave Pattern using While Loop
#include <stdio.h>
int main()
{
int rows;
printf("Enter Right Traingle of Numbers in Sine Wave Rows = ");
scanf("%d", &rows);
printf("Right Traingle of Numbers in Sine Wave Pattern\n");
int num, j, i = 1;
while (i <= rows)
{
printf("%d ", i);
num = i;
j = 1;
while (j < i)
{
if (j % 2 != 0)
{
printf("%d ", num + ((2 * (rows - i + 1)) - 1));
num = num + ((2 * (rows - i + 1)) - 1);
}
else
{
printf("%d ", num + 2 * (i - j));
num = num + 2 * (i - j);
}
j++;
}
printf("\n");
i++;
}
}
The result of the above c program; is as follows:
Enter Right Traingle of Numbers in Sine Wave Rows = 5 Right Traingle of Numbers in Sine Wave Pattern 1 2 9 3 8 10 4 7 11 14 5 6 12 13 15
