To check whether a number is prime or not?

C++ program to find a number is prime or not? Algorithm: Input = number set counter=0; set i=0 to i<=number if(number%i==0) counter=counter+1; i=i+1; if(counter == 2) print"number is prime"; else print "number is not prime"; exit; Approach to solve: Input = 5; number%i=5%1=0 5%2=1 5%3=2 5%4=1 5%5=0 counter=2 so, it will print number is prime. Input =4 number%i=4%1=0 4%2=0 4%3=1 4%4=0 counter=3 so,...

C++ functions

In this article, you will learn about the functions in C++.why and how we use functions. What is a function in C++? A function is a block of code that performs some operation.If we want to use a piece of code again and again in the program we wrap that piece of code in the function and use that piece of code in the program by calling it. There are two types of functions in C++. Library function...

Sum of digits of a number

C++ program to find the sum of digits of a number. Algorithm:- Input=number number1=0, sum=0; while loop > 0 (a) number1 equal to remainder of number divide by 10 number1=number%10; (b) add sum and number1 to sum sum=sum+number1; (c) divide number by 10 number=number/10; print sum; exit; Approach to solve:- Input=259 number1=number%10=9 sum=sum+number1=9 number=number/10=25 number1=number%10=5 sum=sum+number1=14 number=number/10=2 number1=number%10=2 sum=sum+number1=16 number=number/10=0 Program:- #include<iostream> using...

C++ program to check whether a number is palindrome or not?

what is a palindromic number? A palindromic number is a number which remains same when its digits are reversed. Example 121,16461 etc. Let understand the algorithm of the program. Input=number reverse_number=0; temp=number; while loop number > 0 (a)multiply reverse_number by 10 and add remainder of number divide by 10 to reverse_number reverse_number= reverse_number*10+number%10; (b)divide...

How to reverse a number in C++?

Write a C++ program to reverse digits of a number  Reverse number:- Input=7890 Output=0987 Algorithm:- Input=number reverse_number=0; while loop number > 0 (a)multiply reverse_number by 10 and add remainder of number divide by 10 to reverse_number reverse_number= reverse_number*10+number%10; (b)divide number by 10 number=number/10; print reverse_number. Approach to solve:- Input:num=7890 rev_num=0 rev_num=rev_num*10+num%10=0 num=num/10=789 rev_num=rev_num*10+num%10=09 num=num/10=78 rev_num=rev_num*10+num%10=098 num=num/10=7 rev_num=rev_num*10+num%10=0987 num=num/10=0 Program:- #include<iostream> using...

Types Of For Loop

In the previous post, we understand how for loop works and three parts of for loop.In this post, I will discuss the types of for loop or in which way you will use for loop. For loops are mainly two types: Infinite for loop Nested for loop THE INFINITE FOR LOOP:- A loop becomes infinite loop if the condition never becomes false. For loop required three parts to run initialization, test expression,...
