                                1  4   6   4   1 

                             1    5  10 10  5  1

 #include<stdio.h>

 void main()

 {

                    // print pascal triangle

                      int n,g;

                      int i,k,j;

                      clrscr();

                      printf("enter no\n");

                      scanf("%d",&n);

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

                      {

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

                          {  

                                   printf("  ");

                           }

                                g=1;

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

                                    {

                                         if(i==0 || k==0)

                                               printf("  %2d  ",g);

                                                else

                                                 {  

                                                          g=g*(i-k+1)/k;

                                                           printf("   %2d  ",g);

                                                   }

                                       }

                                              printf("\n\n");

                             }

                                      getch();

  }

w.a.p to print no is even or odd.

#include<stdio.h>
#include<conio.h>
void main()
{
     // print no is even or odd
      int a;
       printf("enter number::\n");
       scanf("%d",&a);
       if (a%2==0)
      {
          printf("no. is even\n);
      }
       else
       {
           printf("no. is odd\n");
       }
        getch();
}
out put:-
enter number::
2
no is even

w.a.p to print number positive or negative.

#include<stdio.h>
#include<conio.h>
void main()
{
    // print no. is positive or negative
     int a;
     clrscr();
     printf("enter number::\n");
     scanf("%d",&a);
     if (a>0)
     {
         printf("no. is positive\n");
     }
      else
      {
         printf("no. is negative\n");
       }
       getch();
}
out put:-
enter number
-5
no. is negative
