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

1
121
12321
1234321

Ans.

/*c program for number triangle design*/
#include<stdio.h>
int main()
{
int num,r,c,z;
printf("Enter any number : ");
scanf("%d", &num);

for(r=1; r<=num; r++)
{
for(c=1; c<=r; c++)
printf("%d",c);
for(z=r-1; z>=1; z--)
printf("%d",z);
printf("\n");
}
getch();
return 0;
}

The output of above program would be:

Q. Write a C program to print the following alternate number-star pyramid/triangle as:

1
2*2
3*3*3
4*4*4*4
4*4*4*4
3*3*3
2*2
1

Ans.

/*c program for alternate number-star pyramid*/
#include<stdio.h>
int main()
{
int num,r,c,z=1,p,n;
printf("Enter maximum number : ");
scanf("%d", &num);

for(r=1; r<=num; r++,z=z+2)
{
for(c=1; c<=z; c++)
{
if(c%2==0)
printf("*");
else
printf("%d",r);
}
printf("\n");
}
n=num+3;
/*
NOTE: increase +1 above digit when you increase maximum number to 4
For example: if you enter:
num=5 then n=num+4
if num=6 then n=num+5 and so on.
*/
p=num;
for(r=num; r>=1; r--,n=n-2,p--)
{
for(c=1; c<=n; c++)
{
if(c%2==0)
printf("*");
else
printf("%d",p);
}
printf("\n");
}
getch();
return 0;
}

The output of above program would be:

Diagonal Star and Zero Rectangle

Posted: 23 Aug 2013 12:21 AM PDT

Q. Write a C program to print the following diagonal star and zero rectangle structure as:

*000000
0*00000
00*0000
000*000
0000*00
00000*0
000000*

Ans.

/*c program for diagonal star and zero rectangle*/
#include<stdio.h>
int main()
{
int rows=7,r,c;

for(r=1; r<=rows; r++)
{
for(c=1; c<=rows; c++)
{
if( (c==1 && r==1) ||
  (c==2 && r==2) ||
  (c==3 && r==3) ||
  (c==4 && r==4) ||
  (c==5 && r==5) ||
  (c==6 && r==6) ||
  (c==7 && r==7)
)
printf("*");
else
printf("0");
}
printf("\n");
}
getch();
return 0;
}

The output of above program would be:

Q. Write a C program to print the following vertical continues number pyramid as:

1
23
4
56
7
89
10

Ans.

/*c program for vertical continues number pyramid*/
#include<stdio.h>
int main()
{
int r,c,x,y;

static int i=1;
for(r=1; r<=7; r++)
{
if(r%2==0)
{
for(x=2; x>=1; x--,i++)
printf("%d",i);
}
else
{
for(y=1; y>=1; y--,i++)
printf("%d",i);
}
printf("\n");
}
getch();
return 0;
}

The output of above program would be:
