Number Patterns Example 21 – C Program
write a c program to display triangle number patterns example shows like below patterns.
1
2 3 2
3 4 5 4 3
4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5
#include <stdio.h>
#include<conio.h>
void main()
{
int i, j, k;
for(i=1; i<=5; i++)
{
k=1;
for(j=1; j<=i; j++)
{
printf("%d", k++);
}
k-=2;
for(j=k;j>=i;j--)
{
printf("%d", k--);
}
printf("\n");
}
getch();
}The output of number patterns c program is :
1
2 3 2
3 4 5 4 3
4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5
