  void main()
  {
     int firNum, secNum, tempVar;
     
     printf("Enter first Number: ");
     scanf("%d",&firNum);
     printf("\nEnter second Number: ");
     scanf("%d",&secNum)

     tempVar = firNum;
     firNum = secNum;
     secNum = tempVar;

    printf("\nAfter swapping, first Number: %d",firNum);
    printf("\nAfter swapping, second Number: %d",secNum);
 }

Output:

 Enter first Number: 28
 Enter second Number: 30
 After swapping, first Number: 30
 After swapping, second Number: 28
