Like the alphabet triangle,
we can write the c program to print the number triangle. The number triangle can be printed in different ways.
Let's see the c example to print number triangle.
#include<stdio.h>
#include<stdlib.h>
int main(){
int i,j,k,l,n;
system("cls");
printf("enter the range=");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
for(j=1;j<=n-i;j++)
{
printf(" ");
}
for(k=1;k<=i;k++)
{
printf("%d",k);
}
for(l=i-1;l>=1;l--)
{
printf("%d",l);
}
printf("\n");
}
return 0;
}
Output:
enter the range= 4
1
121
12321
1234321
enter the range= 7
1
121
12321
1234321
123454321
12345654321
1234567654321
