Sample Output: 1. A password must have at least ten…
In the above Java program to display the first 50 pentagonal numbers, we first need to understand what is pentagon? A pentagonal number is a figurative number that extends the concept of triangular and square numbers to the pentagon, but, unlike the first two, the patterns involved in the construction of pentagonal numbers are not…
In the above Java program to count all vowels in a string we use built-in function count() and with the help of a counter variable, calculate each and every vowel. Sample Output: Input the string: welcome To the world of java Number of Vowels in the string: 9
In the above Java program to print a right angles triangle from a number, we have use nested loop where i is row and j is column in that row. Sample Output: Input number of rows : 10 1 12 123 1234 12345 123456 1234567 12345678 123456789 12345678910
To understand the above C++ program to calculate the factorial of a number using recursion, we need to understand what is recursion first. Recursion is a method in C++ which calls itself directly or indirectly until a suitable condition is met. In this method, we repeatedly call the function within the same function, and it…
In the above C++ program to reverse a digit, arithmetic operation is used to get the desired result. Sample Output: Enter an integer: 4367 Reversed Number is : 7634
The above C++ program that accepts different numbers n as well as an integer s which is equal to the sum of the n different numbers, can be understood with the following example : If n = 3 and s = 6:1 + 2 + 3 = 60 + 1 + 5 = 60 +…
In the above C++ program to display all the leap years between two given years, we have used conditional statements in a user defined function. And in the main function the user-defined function is called along with the values of the year entered by the user. Sample Output: Enter two years to specify the range:…
