In the C programming language, when no explicit type is specified for a variable, the default type is indeed `int`. This means that if you declare a variable without specifying its type, the compiler assumes it to be of type `int`. For example, if you write `x;` without declaring `int x;`, it will typically lead to an error unless it is part of a declaration like `int x;`.

This behavior applies to local variable declarations where no type is provided; thus, the compiler defaults to `int`. However, it's important to note that in some specific contexts (such as function parameters or specific structures), the rules can differ slightly, but for basic variable declarations, `int` is the default type.

In cases where explicit typing is necessary—such as defining global variables or handling function parameters—the part of the statement that refers to default types holds, reinforcing the idea that understanding type specifications is crucial in C programming. Additionally, considerations around context and variable scope can lead to diverse interpretations of type defaults, but the foundational behavior remains consistent.
