Generating Various Patterns Using Loops

M Pattern

Code :

main()

{

int i,j,n;

printf("Enter n:");

scanf("%d",&n);

for(i=0;i<n;i++)

{

  for(j=0;j<(4*n-1);j++)

    {

     if(i==(n-1))

       printf("*");

   else

  {

     if((j<(2*i+1))||(j>=((4*n-1)-(2*i+1))))

       printf("*");

     else

       printf(" ");

  }

  }

printf("\n");

}

}

xpattern

Code :

main()

{

unsigned short int i,j,n;

printf("Enter N:\n");

scanf("%hu",&n);

for(i=0;i<=(2*n);i++)

{

for(j=0;j<=n;j++)

{

  if(i<=n)

  {

     if(j<(i))

       printf(" ");

     else

       printf("* ");

  }

  else

    {

    if((n-j)>(i-n))

     printf(" ");

     else

      printf("* ");

    }

  }

   printf("\n");

}

}

Bit Pattern Reversal

Code:

main()

{

int n,num,i;

printf("Input A Number:");

scanf("%d",&num);

n=sizeof(num)*8-1;

printf("Original Bit Pattern:");

for(i=n;i>=0;printf("%d",(num>>i)&1),i--);

for(i=0;i<=n/2;i++)

{

  if(((num>>i)&1)!=((num>>(n-i))&1))

  {

   num ^= (1<<i);

   num ^= (1<<(n-i));

  }

}

printf("\nReversed Bit Pattern:");

for(i=n;i>=0;printf("%d",(num>>i)&1),i--);

printf("\n");

}
