How do I swap numbers in a flowchart?

Algorithm and Flowchart to Swap Two Integer Numbers

  1. Declare a variable a,b and c as integer; Read two numbers a and b; c=a; a=b; b=a; Print a and b.
  2. STEP 1: START STEP 2: ENTER A, B STEP 3: PRINT A, B STEP 4: A = A + B STEP 5: B= A – B STEP 6: A =A – B STEP 7: PRINT A, B STEP 8: END.

How do you swap two numbers with pointers?

  1. #include
  2. int main()
  3. int x, y, *a, *b, temp;
  4. printf(“Enter the value of x and y\n”);
  5. scanf(“\%d\%d”, &x, &y);
  6. printf(“Before Swapping\nx = \%d\ny = \%d\n”, x, y);
  7. a = &x
  8. b = &y

What is pointer write program to swap values of two variables by passing pointers?

Explanation : Swapping Two Variables using Pointer scanf(“\%d”, &num1); printf(“\nEnter the Second number : “); scanf(“\%d”, &num2); Now You need to pass the address of both variables to the function.

What is swapping of two numbers?

Swapping two number in C programming language means exchanging the values of two variables. Suppose you have two variable var1 & var2. Value of var1 is 20 & value of var2 is 40. So, after swapping the value of var1 will become 40 & value of var 2 will become 20.

How do you swap two numbers without using pointers?

Let’s see a simple c example to swap two numbers without using third variable.

  1. #include
  2. int main()
  3. {
  4. int a=10, b=20;
  5. printf(“Before swap a=\%d b=\%d”,a,b);
  6. a=a+b;//a=30 (10+20)
  7. b=a-b;//b=10 (30-20)
  8. a=a-b;//a=20 (30-10)

What are the steps for adding 2 numbers?

(i) Arrange the numbers vertically so that the tens’ place digits and ones’ place digits are lined up which means in simple one number should be written above the other number. Draw a line under the bottom number. (ii) Add first the ones’ place digits. (3 + 2 = 5).

How do you swap two arrays using pointers?

C Program to Accept an Array & Swap Elements using Pointers

  1. Declare an array and define all its elements.
  2. Create a function with two parameters i.e. two pointer variables.
  3. Inside this function, first create a temporary variable.
  4. Now, value at first pointer changes to the value at second pointer.

How do you make a flow chart for a pseudocode?

The flow chart is just composed of “Get user input #1” and “Get user input #2” placed at the start of the pseudocode, then the above lines of pseudocode, and finally “Print a and b” at the end of the pseudocode. Note that most modern CPU architectures ( and for that matter a lot of older CPU architectures ) have dedicated swap instructions.

How do you write pseudocode to swap two numbers without a variable?

“How do you write pseudo code and draw a flowchart to swap two numbers without using a temporary variable?” The flow chart is just composed of “Get user input #1” and “Get user input #2” placed at the start of the pseudocode, then the above lines of pseudocode, and finally “Print a and b” at the end of the pseudocode.
