Number Patterns Example 31 – C Program
write a c program to display triangle number patterns example shows like below patterns.
1
1 2 3
1 2 3 4 5
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7
1 2 3 4 5
1 2 3

#include <stdio.h>
#include<conio.h>
void main()
{
int i, j, k;
for(i=1; i<=5; i++)
{
for(j=i; j<5; j++)
{
printf(" ");
}
for(k=1; k>(i*2); k++)
{
printf("%d",k);
}
printf("\n");
}
for(i=4; i>=1; i--)
{
for(j=5; j>1; j--)
{
printf(" ");
}
for(k=1; k<(i*2); k++)
{
printf("%d", k);
}
printf("\n");
}
getch();
}The output of number patterns c program is :
1
1 2 3
1 2 3 4 5
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7
