Code Explanation :

This is the example of the C program to swap two numbers given by the user.

swap means the interchange of the value between two variables. for example,

Initially, there are two variables number1 and number2 and values on these variables are 10 and 20 respectively.

After swapping, the value of number1 will be 20 and the value of number2 will be 10.

I hope, you know what the swap is.

Let's go through the example.

In this example, we use pointer to swap the value of two variables. We have created two variables of integer type and we take inputs from user.

After that we have called function that we have created (user-defined function) as swap().

Remeber that, we have not passed the variables value in the function. We have passed the variable location using &.

Now, We have passed the variables location in the function but we use the location value using pointer variables *a. We easily swap two variables using c variables and print them.

Goint through the algorith and flowchart, I will recommend not to use the function. Just simply go through the simple synatx as if...else, while and many more.

We can do this program with different method.

C program to swap two number using simple code

#include <stdio.h>
int main()
{
  int x, y, t;

  printf("Enter two integersn");
  scanf("%d%d", &x, &y);

  printf("Before SwappingnFirst integer = %dnSecond integer = %dn", x, y);

  t = x;
  x = y;
  y = t;

  printf("After SwappingnFirst integer = %dnSecond integer = %dn", x, y);

  return 0;
}

C program to swap two number without using extra variable

#include <stdio.h>
int main()
{
   int x, y;
   
   printf("Input two integers (x & y) to swapn");
   scanf("%d%d", &x, &y);
   
   printf("Before SwappingnFirst integer = %dnSecond integer = %dn", x, y);
   
   x = x + y;
   y = x - y;
   x = x - y;

   printf("After SwappingnFirst integer = %dnSecond integer = %dn", x, y);
   return 0;
}

C program to swap two number using pointer without function

#include <stdio.h>
int main()
{
   int x, y, *a, *b, c;

   printf("Enter the value of x and yn");
   scanf("%d%d", &x, &y);

   printf("Before Swappingnx = %dny = %dn", x, y);
   
   a = &x;
   b = &y;
   
   c = *b;
   *b   = *a;
   *a   = c;

   printf("After SwappingnFirst integer = %dnSecond integer = %dn", x, y);
   
   return 0;
}e

C program to swap two number using bit-wise XOR

#include <stdio.h>
int main()
{
  int x, y;

  printf("Enter the value of x and yn");
  scanf("%d%d", &x, &y);

  printf("Before SwappingnFirst integer = %dnSecond integer = %dn", x, y);

  x = x ^ y;
  y = x ^ y;
  x = x ^ y;

  printf("After SwappingnFirst integer = %dnSecond integer = %dn", x, y);

  return 0;
}

Although there used different method but the final output of program is same as given above. So, that we are representing common algorithm and flowchart.

Algorithm

Step 1 : Start 

Step 2 : Declare x, y, x

Step 3 : Read x and y

Step 4 : Print "Before swapping, x and y"

Step 5 : Set value of x on z i.e z = x;

Step 6 : Set value of y on y i.e  x = y;

Step 7 : Set value of z on y i.e y = z;

Step 8 : Print "After swapping, x and y"

Step 9 : end
