C++ Program to Add Two Numbers
In this article, we'll show how to add two numbers using C++ and display the result. Adding two numbers is a basic arithmetic operation, meaning we combine their values to get a total. We will see different methods to solve this. Different Ways to Add Two Numbers in C++ In C++, there are various approaches to add two numbers, each approach using its own cases and advantages. Below are the mentioned list: Using Addition Operator Using User Input Using Increment and Decrement Operators ...
Read MoreHow to eliminate repeated lines in a python function?
In this article, we will discuss how to delete multiple lines that are repeated in a Python Function. If the file containing the program is small and only has a few lines, we can remove repeated lines manually. However, when dealing with huge files, we need a Python program to do so. Using the File Handling Methods Python has built-in methods for creating, opening, and closing files, which makes handling files easier. Using the methods, we can also perform several file actions, such as reading, writing, and appending data (while files are open). To remove duplicate lines from a text ...
Read MoreC++ Program to Calculate Power of a Number
In this article, we'll show you how to calculate the power of a number in C++. Calculating a power means multiplying the base by itself as many times as the exponent indicates. For example, 2 raised to the power of 3 (2^3) means multiplying 2 by itself three times: 2 * 2 * 2, which gives 8. In C++, there are different ways to calculate the power of a number. Below are the approaches we cover: Using a Loop Using Recursion Using the pow() Function ...
Read MoreC++ Program to Check Whether a character is Vowel or Consonant
In this article, we'll show you how to write a C++ program to check if a given character is a vowel or a consonant. Vowels are the letters 'a', 'e', 'i', 'o', 'u'(both uppercase and lowercase), and all other alphabetic characters are consonants. For example, if we input the character 'a', the program will output 'vowel'. If we input 'b', it will output 'consonant'. In C++, there are different ways to check if a character is a vowel or consonant. Below are the common methods: Using an if-else statement ...
Read MoreC++ Program to Implement the linear congruential generator for Pseudo Random Number Generation
The Linear Congruential Generator (LCG) is a very simple technique to generate a sequence of numbers that looks like random numbers but is actually determined. It is one of the reasons to call it a pseudo-random number. The Linear Congruential Generator (LCG) technique generates a random number based on the previous number and uses a linear recurrence to generate the sequence of random numbers. In this article, we have set an initial value of Xn and defined the value of the constants. Our task is to generate pseudo-random numbers using the linear congruential generator in C++. Formula of Linear ...
Read MoreC++ Program to Implement Sorting of Less than 100 Numbers in O(n) Complexity
To sort less than 100 numbers in O(N) complexity, we can use the counting sort technique. The counting sort is a stable and non-comparison-based sorting technique, that is used to sort the objects according to the keys that are small integers. It counts the number of keys whose key values are same. It works by counting the occurrences of elements in the array. This sorting technique is efficient when difference between different keys are not so big, otherwise it can increase the space complexity. In this article, we have an unsorted array containing twelve elements. Our task is to sort ...
Read MoreC++ Program to Implement Segmented Sieve to Generate Prime Numbers Between Given Range
The Segmented Sieve algorithm is used to find the prime numbers within a given range. Segmented Sieve first uses the Sieve of Eratosthenes algorithm to find the primes smaller than or equal to √(n). The idea of this algorithm is to divide the range [0 ... n-1] in different segments and compute primes in all segments one by one. In this article, we have a range defined from low to high. Our task is to implement the Segmented Sieve to find the prime numbers within the given range in C++. Example The following example generates all the prime numbers between ...
Read MoreCatching base and derived classes exceptions in C++
To catch an exception for both base and derived classes, we need to put the catch block of the derived class before the base class. Otherwise, the catch block for the derived class will never be reached. This happens because C++ follows a top-down approach when checking catch blocks. So, by placing the derived class catch block first, we ensure that specific exceptions are handled correctly before falling back on the base class. Algorithm Following is the algorithm to catch Base and Derived classes Exceptions in C++: Begin Declare a class B. Declare another ...
Read MorePrint “Hello World” with empty or blank main in C++
In this problem, we will see how to print "Hello World" into the console, but we cannot write anything into the main function. This problem can be solved in different ways. Initially, we will create a global variable, then we will store the returned value of the printf() function into that variable. When printf() is executed, then it will be printed. You can print "Hello World" without using the logic inside the main() function in different ways, such as using Global Constructors, Class Object and macros, or preprocessor, etc. Using Global Constructor A global constructor is the constructor of a global object ...
Read MoreHow to pass a json object as a parameter to a python function?
We can pass a JSON object as a parameter to a Python function using the json.loads() method. we can also convert the JSON string into a Python dictionary or list, which depends on its structure. Once converted, the data can be used just like any other dictionary or list in Python. JSON Object Consider a JSON object to pass to a python function. We will use it further in this article - { "name":"Rupert", "age": 25, "desig":"developer" } Using json.loads() Function Before passing a JSON object as a parameter ...
