In this article, we will understand how to count the vowels and consonants in Kotlin. Alphabets that include the following are called Vowels − ‘a’ ‘e’ ‘i’ ‘o’ ‘u’ All other alphabets are called Consonants. Suppose our input is − Hello, my name is Charlie The desired output would be − The number of vowels in the statement is: 8 The number of vowels in the Consonants is: 12 Algorithm Step 1 − Start Step 2 − Declare two integers: vowelsCount, consonantsCount and a string input Step 3 − Define the values Step 4 − Run ...

In this article, we will understand how to calculate the sum of natural numbers in Kotlin. All possible positive numbers from 1 to infinity are called natural numbers. Below is a demonstration of the same − Suppose our input is 1 and 100 The desired output would be − Sum of natural numbers from 1 to 100 is 3825 Algorithm Step 1 − Start Step 2 − Declare an integers input Step 3 − Define the integers Step 4 − Run a for-loop, add the number with its next number until the upper limit is reached. Store ... Read More
In this article, we will understand how to calculate the roots of a quadratic equation in Kotlin. A quadratic equation is an algebraic expression of the second degree or in other words, it has two results i.e., real number and an imaginary number. Below is a demonstration of the same Suppose our input is − a = 1, b = 2, c = 3 The desired output would be − The roots of the quadratic equation are root1 = -1.00+1.41i root2 = -1.00-1.41i Algorithm Step 1 − Start Step 2 − Declare six values: inputA, inputB, inputC, ...

In this article, we will understand how to find the largest of three integers in Kotlin. This is done using a greater than operator (= input2 && input1 >= input3) println("The first value i.e $input1 is the largest number.") else if (input2 >= input1 && input2 >= input3) println("The second value i.e $input2 is the largest number.") else println("The third value i.e $input3 is the largest number.") Let us now see the complete example to find the largest among three numbers in Kotlin − fun main() { ... Read More
In this article, we will understand how to compute the quotient and reminder in Kotlin. Quotient and Reminder is calculated using two simple formulae − “Quotient = Dividend / Divisor” “Remainder = Dividend % Divisor” Below is a demonstration of the same Suppose our input is − Dividend value: 50 Divisor: 3 The desired output would be − Quotient: 16 Remainder: 2 Algorithm Step 1 − Start Step 2 − Declare four integers as myDividend , myDivisor, resultQuotient, resultRemainder Step 3 − Define the integers Step 4 − Use the formula to find the quotient and ...

In this article, we will understand how to print ascii values of characters. This is done by assigning the character to an integer value and printing those integer values. Below is a demonstration of the same Suppose our input is − Enter a character: s The desired output would be − Ascii value of s is 115 Algorithm Step 1 − Start Step 2 − Declare a char as input Step 3 − Define the character Step 4 − Assign the character to an integer variable using toInt() function and store it in myResult. Step 5 − ... Read More
In this article, we will understand how to compute the surface area and volume the cuboid. The surface area of cuboid is calculated using the formula − 2*( length *width + width* height + height*length) The Volume of the cuboid is calculated using the formula length*width*height Below is a demonstration of the same − Suppose our input is − length= 6; width= 7; height= 8; The desired output would be − Volume Of the Cuboid is : 336.0 Surface area Of the Cuboid is : 292.0 Algorithm Step 1 − START Step 2 − Declare ...
