In C programming, when two variables share the same name but are in different scopes, what is true?

When two variables share the same name but exist in different scopes in C programming, the inner variable takes precedence. This means that within the inner scope, any reference to the variable will refer to the inner variable rather than the outer one.

In C, scope refers to the context in which a variable is defined and can be accessed. When a variable is declared within a block (for example, within a function or a loop), it shadows any variable with the same name that may exist in an outer scope. Consequently, if you try to access the variable inside the block, the inner version will be used. This behavior allows for better management of namespaces and reduces the risk of unintended interference from outer variables.

For instance, if you have a global variable named "x," and then you declare another variable called "x" within a function, any use of "x" within that function will refer to the function's local variable, leaving the global "x" untouched unless explicitly accessed through its scope.

Understanding variable scope is crucial in programming as it helps maintain clean and efficient code, avoiding accidental misuse of variables. In this context, the outer variable is still defined and can be accessed from outside the inner scope, but any direct usage within that inner scope will
