C Program to print numbers from 1 to N without using semicolon
Printing numbers from 1 to N is an easy task that can be achieved using loops, but to print numbers from one to N without using a semicolon is a tricky question. We will discuss two different methods to solve this question using iteration and recursion approaches. In this article, our task is to print numbers from 1 to 'n' and we don't have to use a semicolon. The approaches are listed below: Using Iteration Using Recursion Using Iteration This approach uses the iterative approach, where we have used the while loop to print the numbers from 1 to N. The num
Read MoreC Program to sum the digits of a given number in single statement
The calculation of the sum of the digits of a number in a single statement means that only one line of code will be doing the addition operation. The addition operation should not extend more than one statement. In this article, we have a number and our task is to calculate the sum of the digits of the number in a single statement in c. Here is a list of approaches: Using for Loop Using Recursive Function Using for Loop This approach uses a for loop to calculate the ...
Read MoreC++ Program to Emulate N Dice Roller
Emulating an n dice roller refers to rolling n number of dice simultaneously. In each roll, all the dice will return a different value from 1 to 6. In this article, we are having 'n' number of dices, our task is to emulate rolling n dices simultaneously. The approaches are mentioned below: Using Loop with rand() Function Using Recursion Using Loop with rand() Function In this approach, we have used the rand() function to generate a random value of dice in each roll. The srand() function with time() is ...
Read MoreC++ program to convert Fahrenheit to Celsius
To convert fahrenheit to celsius, use a simple mathematical formula. In this article, we are going to discuss the conversion formula, a simple example, and an easy example code. We have been given a temperature in fahrenheit and our task is to convert the given temperature into celsius using C++. Understanding Fahrenheit to Celsius Formula The formula for converting the given temperature from fahrenheit to celsius is as follows: celsius = (fahrenheit - 32.0) * 5.0 / 9.0; Let's see an example to convert the temperature given in fahrenheit to celsius using the above formula: Input: Temperature in ...
Read MoreC++ Program to Find the GCD and LCM of n Numbers
The gcd refers to 'Greatest Common Divisor', i.e. greatest common number which can divide all the given numbers. The lcm refers to the 'Least Common Multiple' i.e. the lowest common multiple of all the numbers. To find the gcd and lcm of n numbers in C++, we can use various approaches like iterative approach, or built-in C++ functions. In this article, we are having 'n' number of elements, our task is to find the gcd and lcm of n number of elements using C++. Example Here is an example of GCD and LCM of 4 numbers: Input: Numbers = ...
Read MoreHow do I convert a double into a string in C++?
A double datatype is used to represent a decimal or exponential value and string represents a sequence of characters. In this article, we are having a double value and our task is to convert the given double into string. Here is a list of approaches to convert double to string in C++ that we will be discussing in this article with stepwise explanation and complete example codes. Using to_string() Function Using ostringstream Using stringstream Using sprintf() Function Using ...
Read MoreHow to write long strings in Multi-lines C/C++?
To write long strings in multi-lines, you can use 'newline character' or 'raw string literal'. It increases the readability of the code, makes the code look clean, and you can avoid scrolling. In this article, we have a long string and our task is to write the long string in multi-lines in C++. Approaches to Write Long Strings in Multi Lines Here is a list of approaches to write long strings in multiple lines which we will be discussing in this article with stepwise explanation and complete example codes. Using Newline Character ...
