admin Previous Next The postfix expression is a notation for expression used in computers where operator comes after the operands in the expression. It is also known as reverse polish notation. In this example, you will learn evaluating postfix expression using stack. Suppose A and B are two operand and '+' is the operator. We humans … Read more
This C program checks a given string whether it is a palindrome or not. The string is read from left to right and right to left and each character is matched. If all the characters in the input string match correctly, then it is a palindrome string, otherwise not. This program is written using Dev … Read more
This C program checks an input number whether it is an Armstrong number on not and prints the results. An Armstrong number is special number sum of the nth power of its every digit is equal to the original number. The n is the number of digits in the input number. This concept is explained … Read more

To help you understand this program, we have the following sections – problem definition, flowchart, program source code, and verified output. In this C program, we want to compute … Read more
Data types describe the kind of data so that computer can store or manipulate them appropriately. This is the reason to declare a data type in C++ programming. Data types are also necessary because data items such as numbers are used in expressions. If there is a mismatch, for example – integer and real numbers … Read more
