Swapping of Two Numbers in C - Scaler Topics

SpletThe basic idea is to transfer the value of one variable to another and take the value of the second variable and put it to first. Example: a = 6 b = 3 swap (a,b) //using a swap function print("%d", a) //3 print("%d", b) //6. Note that value of variables a and b … SpletThere are two common ways to swap two numbers without using third variable: By + and - By * and / Program 1: Using + and - Let's see a simple c example to swap two numbers without using third variable. #include int main () { int a=10, b=20; printf ("Before swap a=%d b=%d",a,b); a=a+b;//a=30 (10+20) b=a-b;//b=10 (30-20) a=a-b;//a=20 (30-10) marvel ultimate fuel \u0026 motor treatment

Swap Two Numbers In C Programming In Different Ways

SpletC program to swap two numbers with and without using third variable, using pointers, functions (Call by reference) and using bit-wise XOR operator. Swapping means interchanging. If the program has two variables a and b where a = 4 and b = 5, after swapping them, a = 5, b = 4. In the first C program, we use a temporary variable to swap … Splet16. feb. 2024 · Swapping two numbers without using a temporary variable: Approach: the simple idea behind this code is to use arithmetic operators. We will take the sum of the two numbers and store it in one number and store the difference of both the numbers in … SpletSwapping Using Third Variable. This method is also popularly known as Swapping Using Temporary Variable. Let’s take an interesting example to understand this concept well. Suppose we have three glasses.
