Swapping two integers in a computer language means switching the values of two variables. Think about the variables var1 and var2 you have. Var1 is valued at 20, whereas Var2 is valued at 40. As a result, after swapping, var1 and var2 will have values of 40 and 20, respectively. This blog post will teach you how to swap two variables in C.<\/p>\n

Algorithm to Swap Two Numbers in C:<\/h2>\n
    \n
  1. START<\/li>\n
  2. ENTER x, y<\/li>\n
  3. PRINT x, y<\/li>\n
  4. x = x + y<\/li>\n
  5. y= x – y<\/li>\n
  6. x =x – y<\/li>\n
  7. PRINT x, y<\/li>\n
  8. END<\/li>\n<\/ol>\n

    Different Methods to Swap Two Numbers in C:<\/h2>\n

    1. Swapping Two Numbers Using Third Variable<\/li>\n
    2. Swapping Two Numbers Using Without Using Third Variable<\/li>\n
    3. Swapping Function in C<\/li>\n
    4. Swap two numbers using pointers in C<\/li>\n
    5. Swap Two Numbers Using Bitwise XOR<\/li>\n<\/ol>\n

      We will look at each one of them one by one.<\/p>\n

      Method 1: Swapping Two Numbers in C Using Third Variable Logic<\/h3>\n

      To swap two numbers, the idea behind using a third variable is simple. Put the value of a temporary variable into the first variable. Put the value of the second variable into the first one. Add the value of the temp variable to the second variable at the end. We are using a temporary variable in our program to store the value of the first variable.<\/p>\n

        \n
      • Assign var1 value to a temp variable: temp = var1<\/li>\n
      • Assign var2 value to var1: var1 = var2<\/li>\n
      • Assign temp value to var2: var2 = temp<\/li>\n<\/ul>\n
