Introduction

String:

In computer programming, a string is a collection of characters. It is frequently used for data types, such as a phrase, prison terms, or a paragraph. Strings are frequently used to store and deceive text data in many computer languages, such as C++, Python, Java, and many others. To distinguish them from those other types of data, they are literally covered by quotations, either single or double. In C++, for example, a string might be proclaimed as follows:

string str = "Hello, World!";

Standard mathematical function:

A standard mathematical role is a clearly defined feature that can be expressed mathematically and visualizations input prices to output signals in accordance with a set of rules. It is a fundamental principle in mathematics and is broadly utilized in fields like science, technology, economics, and computer programming. The square wave, cosine, and exponential functions are instances of standard mathematical functions.

A function is typically defined in mathematics by an equation that describes the connection between input data (also recognized as independent factors) and output data (also known as dependent variables). The standard mathematical purpose for solving the equation of a straight line, for example, is y = mx + b, in which m is the line's slope and b is the y-intercept.
