2) Write a program to accept two numbers & swap them without an extra (third) variable.

#include <stdio.h>
#include <conio.h>

void main()
{
          int a, b;
          printf("Enter two numbers : ");

          scanf("%d%d", &a, &b);
          printf("nOriginal values are a = %d b = %d", a, b);

          a = a + b;
          b = a - b;
          a = a - b;

          printf("nAfter exchange a = %d b = %d", a, b);
          getch();
}
Output:
Enter two numbers: 10 20
Original values are a = 10 b = 20
After exchange a = 20 b = 10

3) What is the output of the following program? – 3 Number value equation

void main()
{
          int intN = 55;
          int intM = 10;
          char X = 'A' ;
          intN +=50;

          printf("1. Updated value of intN ID % FN", X);
          printf("2. Updated value of X is % dn", X);

          X='B';
          printf("3. Updated value of X is % cn", X);

          intN -=8;
          printf("4. Updated value of intN is %dn",intN);

          intN++;
          printf("5. Updated value of intN is %dn", intN);

          intN= intN++  + ++ItM;
          printf("6. Updated value of intN is ;%d intM is;%dn", intN, intM);
}
Output:
1. Updated value of intN is 105
2. Updated value of X is 65
3. Updated value of X is B
4. Updated value of intN is 97
5. Updated value of intN is 98
6. Updated value of intN is:110 intM is:11
