In this tutorial, we will learn how to determine whether the given input is an integer is or not.
varboolResult3 = Methods.CheckIfIntegerWithEqualityOperator(0); Console.WriteLine(boolResult3); Running the examples yields the expected output: True False True Using Explicit Conversion to Check if an Object is a Number As programmers, we have the option to useexplicit conversionby specifying the...
In this article, we will come to know how to use the C language to analyze if a particular integer is even or odd. The term “even number” refers to an integer value that would be completely divided by 2. We would evaluate if an integer is even or odd by using the modulus (%) ...

Enter a positive integer: 29 29 is a prime number. In the program, a for loop is iterated from i = 2 to i < n/2. In each iteration, whether n is perfectly divisible by i is checked using: if (n % i == 0) { flag = 1; break; } If n is perfectly divisible by i, n...

Given a positive number, check if it is a perfect square without using any built-in library function. A perfect square is a number that is the square of an integer. For example, Input:n = 25 Output:true Explanation:25 is a perfect square since it can be written as 5×5. ...
