Why Does My C Loop Outside a Function Cause a Compiler Error?

Code Placement in C

While writing C code, it's crucial to follow proper structure and organization. One aspect of this is the placement of code within functions.

In your case, you have a code snippet written outside any function. This is not permitted in C . Code must be enclosed within functions, and only declarations and definitions can exist outside of functions.

In particular, you've placed a loop structure outside a function:

int l, k;
for (l = 1; l <p>The compiler error you're encountering indicates that the compiler expects an unqualified identifier before for, and that it expects a constructor, destructor, or type conversion before </p><p>To resolve this issue, you should move the code within a function. For instance, you could create a function called initializeFlow() and place the code there:</p><pre class="brush:php;toolbar:false">void initializeFlow()
{
    int l, k;
    for (l = 1; l
