Q. Write a C program to print the following continues odd reverse number pyramid pattern as:

1
6 2
10 7 3
13 11 8 4
15 14 12 9 5

Ans.

Before we start to write the code for above continuous diagonal number pyramid C program, let's focus on below image for better understand the structure of pattern.

/*c program for continuous diagonal number pyramid pattern*/
#include<stdio.h>
int main()
{

int num,r,c,m,n,z,a;
printf("Enter No. of Rows : ");
scanf("%d", &num);
z=num;
n=1;
for(r=1; r<=num; r++, n=n+7-r, z--)
{
m=n;
a=num-r;
for(c=1; c<=r; c++, m=m-a)
{
printf(" %d ", m);
a++;
}
printf("\n");
}
getch();
return 0;
}
