To memorise the few fundamental multiplication results in tabular or graphic form, use multiplication tables. This article will cover how to produce a multiplication table in C++ that looks like a right-angled triangle. In a select few situations where a larger number of results may be easily memorised, triangular representation is effective. In this format, a table is shown row by row and column by column, with each row containing only the entries that fill that column. To solve this problem, we need basic looping statements in C++. For displaying the numbers in triangular fashion, we need nested looping to ... Read More

While writing a program in any language, taking input is a fundamental job that we do in almost all programs. Sometimes we take input directly from the console or take the inputs from the files. Taking inputs from the files is somewhat beneficial because it does not require us to type inputs again and again, or sometimes we can save some good input test cases into a file. However, in this article, we are going to focus on console-based inputs. We will learn different techniques to get inputs from the user in C++. There are a few different approaches to ... Read More

Representing numbers in outputs is an interesting and also important task while we are writing programs in any language. For integer type (short, long, or medium) type data, it is easy to express the numbers as output. For floating point numbers (float or double type), sometimes we need to round them off to certain decimal places. For example, if we want to represent 52.24568 up to three decimal places, some pre-processing needs to be done. In this article, we shall cover a few techniques to represent a floating-point number up to a certain decimal placed by rounding it off. Among ... Read More

After calculating interest on the principal amount, simple interest is calculated by taking the principal amount, the rate of interest, and the number of years it will take to calculate interest. The formula is quite easy to understand. The power law is used to calculate compound interest by taking into account the principal amount, the rate of interest, and the period. Here, the formula is likewise not difficult. In this article, we'll talk about how to calculate simple and compound interest values and then use the C++ programming language to put this logic into practice. Simple Interest Simple interest is ... Read More
