Q. Write a C program for print the following number triangle:
5
454
34543
23454321
123454321
Ans.
/*c program for number pyramid*/
#include<stdio.h>
#include<conio.h>
int main()
{
int r,num,n,i,j;
printf("Enter number of rows : ");
scanf("%d", &num);
n = num;
for(r=1; r<=num; r++,n--)
{
for(i=n; i<=num; i++)
printf("%d", i);
for(j=num-1; j>=n; j--)
printf("%d", j);
printf("\n");
}
getch();
return 0;
}
The output of above program would be:
