• 032. Write a program to print table of a given number n in C language

  #include<stdio.h>
  #include<conio.h>  
  main()
  { 
   int i,n;
   clrscr();
   printf("Enter number : ");
   scanf("%d",&n);
   for(i=1;i<=10;i++)
  	printf("%d X %d = %d\n",n,i,n*i);
   getch();
  }
  
  
  

• 033. Write a program to print sum of given first n numbers in C language

  #include<stdio.h> 
  #include<conio.h>  
  main()
  {
   int n,newn,i,sum=0;
   clrscr();
   printf("Enter number : ");
   scanf("%d",&n);
   printf("Numbers entered....\n");
   for(i=1;i<=n;i++)
   {
  	scanf("%d",&newn);
  	sum=sum+newn;
   }
