# Write A Function Min That Has Three C String Parameters And Returns The Smallest.

C string functions are a way to perform complicated tasks that require many steps. Some of these steps may be difficult or impossible to accomplish using other APIs, like writing your own filter function.

For example, filter_html_entities() and html_tag() return HTML tags, so you can create a function that returns the smallest tag possible. Or create a function that returns the character whose character equivalent is equal to the string parameter.

These functions are called string function because they return a string instead of bytes or nothing at all. You can use them in JavaScript, PHP, and Python!

## Min function

The minimum function can have three string parameters. The second parameter should be the smallest of the other two.

The third parameter should be a number. The number should be returned as the smallest of the other two.

This is useful when you want to rank some element by a certain value, like a score or rating. For instance, you may want to find the first element that has a score of 1, the second that has a score of 10, and the third that has a score of 20.
Whether you use an index or an actual value, both should work!

When used, the minimum function can return a number or an element from |>. Either way, neither should require quotation marks or spelling! |>| can be read as three words: lowest, min, and social-proof-caution-worried-about-typos-because-they-look-smoothly|>|.

## String comparison

Finding the smallest string parameter in a function is a challenging task, don’t worry, we will teach you how to do it in this article.

When writing a function that returns a string, you have two choices for the third parameter: None or an empty string.

None returns the empty string, whereas an empty string returns nothing. Using an empty string means that your function can return something else once, such as a button click or message.

If you return an empty string, your function can return something else instead of nothing because an error could be returned if no value is returned.

## Declare and define variables

Variable names are called variable names because they refer to placeholders for data. In this case, the variable called \$txt is referred to as the \$txt parameter.

To determine if a parameter has a specific size, check its length property. If the parameter has no other properties, then its length property must be zero.

If a parameter has other properties, then it must be marked as optional so your code can tell if it is small or not. If your code does not make sure that \$txt is small, then it may cause problems such as being dropped from an array or query due to having only one value.

The three parameters of a function should all have same lengths in order for the function to work.

The function header is used to group functions together. There are two ways to create a function header.

The first is to put the word Function in the middle of the line and then add your function’s parameters and return statement.

The second is to put the word Header in the middle of the line and then add your parameters and return statement.
Whether you add the term Function or Header, you must do it! There is no space between them.

Write the simplest possible code that returns the smallest number. This can be a string, numeric, or even a simple Action/Paragraph. An easy way to do this is by using the + (+) and * (*) operators to find the smaller of two values. (**) is used to return the bigger of two values.
If you are unfamiliar with these functions, they return a number smaller than another number. For example, (+) returns an integer, and (*) returns a real. (-) returns a float, and (**)) returns an action/paragraph.

## Call the min function

The min function has a slight problem: It can only return the smallest value for its third parameter.

This is because the third parameter is a string, and strings can’t have numbers in them. But, we can use regular expressions to convert values into numbers.

For example, the number 1 matches the regular expression .*\$, so 1 gets converted into an int.

We can use this int to compare two objects: The first one was 5, and the other one was 10. If we compare them with an equal size of 5, then they are smaller than 10, so our function returns 0.

If we used a larger value for the third parameter, then our function would return 1 instead of 0. This would change how our program compared objects.

## Passing string arguments

Pass string arguments via a function parameter is a common way to consume more space in code, however it can help reduce complexity and increase readability.

When writing a function that takes three strings as arguments and returns a string, you could pass the first two as the second argument. For example, return “abyss” + “azure” + “azure”;.

By passing the third argument as the second parameter, you get to use the remaining two strings instead. For example, return “abyss” + “azure” + “azure”;.

This can be useful when you want to produce a string that represents both an AZURE domain and an AZURE application, for example. You would then use this string in your application because it contains Azure values such as prices and availability.

## Returning the smallest value

In the example bullet point, we return the smallest value in our function by passing the smallest value in our parameter list.

Parameter lists are a common way to structure code. They can be passed by reference, or pointer, or even input parameters.

When passing a parameter by reference, the variable that receives the parameter is also passed by reference. If you want to change the value of this variable, then you must give up any attempt at automatic layout and auto-configuration.

However, if you give up trying to configure your variable with layout and auto-configuration, then you will have to wait longer for your code to run due to chances of memory corruption and loss of data.
