Can I Use Ranges in Case Statements in a C Switch Statement?

How do I Select a Range of Values in a Switch Statement in C ?

In C , a switch statement allows you to execute different code depending on the value of a variable. Typically, you use individual case statements for each value you want to check. However, in some programming languages, you can use a range of values in a case statement.

For example, consider the following code:

switch (score) {
    case >= 100:
        // ...
        break;
    case >= 50:
        // ...
        break;
    // ...
}

This code is attempting to use a range of values in the case statements, but it will result in a compiler error because C does not support this syntax.

To fix this problem, you can use a series of individual case statements for each value in the range. For example:

switch (score) {
    case 100:
    case 101:
    case 102:
        // ...
        break;
    case 50:
    case 51:
    case 52:
        // ...
        break;
    // ...
}

Alternatively, some compilers may support an extension to the C language that allows you to specify a range of values in a case statement using the following syntax:

switch (score) {
    case 0 ... 9:
        // ...
        break;
    case 10 ... 24:
        // ...
        break;
    // ...
}

However, it is important to note that this extension is not supported by all compilers, so it is best to avoid using it if you need to support multiple compilers.
