Final answer:
The stringToInteger and stringToReal functions are used to convert string representations of numbers to actual integer and floating-point values in computer programming.
Step-by-step explanation:
The purpose of the stringToInteger function is to convert a string representation of an integer to an actual integer value in a programming language. This is useful when you need to perform calculations or comparisons with the integer value.The purpose of the stringToReal function is similar, but it converts a string representation of a real number (such as a decimal) to an actual floating-point number in a programming language.These functions are commonly used in programming to handle user input, process data from files, or convert data between different formats.
