Chapter 6: Problem 47

\(\mathrm{T} \quad \mathrm{F} \quad\) Many functions may have local variables with the same name.

Short Answer

Expert verified
Answer: True (T)

Step by step solution

01

Understand Local Variables

Local variables are variables that are declared within a function or a block of code, and they are only accessible within that specific function or block. Their scope is limited to the particular function, which means they are not available outside of it.
02

Determine the Possibility of Functions Having Local Variables with the Same Name

Since local variables have a limited scope, it means that they only exist within the function they are declared in. Once the function has finished executing, the local variable is destroyed, and its memory is released. As a result, if there are several functions and each has a local variable with the same name, these local variables are completely independent of each other. They can potentially have different values and will not conflict or cause errors in the program.
03

Evaluate the Given Statement

According to our analysis, having local variables with the same name in many functions is possible, as their existence is limited to the scope of their respective functions. They do not interfere with one another, so the given statement is true.
04

Conclusion

\(\mathrm{T} \quad \mathrm{F} \quad\) Many functions may have local variables with the same name. The correct answer is: True (T).

\(\mathrm{T} \quad \mathrm{F} \quad\) The scope of a parameter is limited to the function which uses it.

T \(\quad$$F \quad\) When a function with default arguments is called and an argument is left out, all arguments that come after it must be left out as well.

A program contains the following function. void display(int arg1, double arg2, char arg3) { cout << "Here are the values: " << arg1 << " " << arg2 << " " << arg3 << endl; } Write a statement that calls the procedure and passes the following variables to it: int age; double income; char initial;

\(\mathrm{T} \quad \mathrm{F} \quad\) A stub is a dummy function that is called instead of the actual function it represents.

\(\mathrm{T} \quad \mathrm{F} \quad\) Static local variables are not destroyed when a function returns.
