Q. Write a C program to print the following equilateral triangle number design as:

5
454
34543
2345432
123454321

Ans.

/*c program for equilateral triangle design*/
#include<stdio.h>
int main()
{

int num,r,c,sp,n;
printf("Enter no. of rows : ");
scanf("%d", &num);
for(r=1; r<=num; r++)
{
for(sp=num-r; sp>=1; sp--)
printf(" ");
for(n=num-r+1; n<=num; n++)
printf("%d",n);
for(c=1,n=num-1; c<r; c++,n--)
printf("%d",n);
printf("\n");
}
getch();
return 0;
}

The output of above program would be:

Ans.

/*c pyramid program for z-shape*/
#include<stdio.h>
int main()
{

int num,r,c,sp,n;
printf("Enter no. of rows : ");
scanf("%d", &num);
for(r=1; r<=num; r++)
printf("*");
printf("\n");
for(r=1,n=num-1; r<=num-2; r++,n--)
{
for(sp=1; sp<n; sp++)
printf(" ");
printf("*");
printf("\n");
}
for(r=1; r<=num; r++)
printf("*");
printf("\n");
getch();
return 0;
}

The output of above program would be:

1
21
321
4321
54321

Ans.

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

int num,r,c,sp;
printf("Enter no of rows : ");
scanf("%d", &num);
for(r=1; r<=num; r++)
{
for(sp=num-r; sp>=1; sp--)
printf(" ");
for(c=r; c>=1; c--)
printf("%d",c);
printf("\n");
}
getch();
return 0;
}

The output of above program would be:
