## C Eval function for strings

This is a simple C function that evaluates a string as a mathematical expression. It is a simple implementation of the shunting yard algorithm. It is not a full implementation of the algorithm, but it is enough to evaluate simple expressions.

Could potentially be used to create entire interpreters for simple languages.

### Usage

```c

#include 

#include "sledeval.h"

int main() {

    char *expression = "2 + 2 * 2";

    int result = eval(expression);

    if (result != 6) {

        printf("Test failed: %s = %d (expected 6)\n", expression, result);

        passed = 0;

    } else {

        printf("Test passed: %s = %d\n", expression, result);

    }

    return 0;

}

```
