Why do local variables lose their values between calls to the function in which they are defined?
They are designed to work that way - and it's actually quite useful to have variables that work that way. If you want to keep a value from one method call to the next, you have to use some other way to store the information. For example, you can store information in an object field.

Write a program that defines a template function named add This function takes two arguments add two variables and then return the sum?
Write a program that defines a template function named add(). This function takes two arguments, add two variables and then return the sum. In main function, define two variables of type int, two variables of type float and two objects of type 'String'. Now call the add() function three times for these different data types. Note: String is a user-defined data type and for this you have to define a class named 'String'. When template function will be called to add two objects of type String then it must concatenate two strings. Your output should look like this: Sample Output: Enter two integer values to be added Enter First value: 12 Enter Second value: 25 Enter two float values to be added Enter First value: 13.5 Enter Second value: 14.2 Enter two Strings to be added Enter First value: Virtual Enter Second value: University Addition of two variables of different data types Sum of values of type int = 37 Sum of values of type float = 27.7 Sum of values of type String = VirtualUniversity
Explain different types of variables in shell?
Environment Variables: Sometimes called special shell variables, keyword variables, predefined shell variables, or standard shell variables, they are used to tailor the operating environment to suit your needs. Examples include PATH, TERM, HOME, and MAIL.User-defined Variables: These are variables that you create yourself.Positional Parameters: These are used by the shell to store the values of command-line arguments
How do you use pow function in c?
Either you can use the pre defined function "pow" in the <math.h> header file OR you can make a user defined function to do the same operation. 1.Using the pre defined function in <math.h> : The function is a of datatype double and accepts only values in double. So, prototype declaration is: double pow(double x,double y); Pass the values to the function and it'll return the value of xy. In the calling function it can be declared as: double power=pow(x,y); 2.USER DEFINED FUNCTION: double power(double x,int y); int main() { double x,result; int y; cout<<"\nEnter the base: "<<; cin>>x; cout<<"\nEnter the exponential power: "; cin>>y; result=power(x,y); cout<<"The result of x to the power y is: "<<result; return 0; } double power(double x,int y) { for(int i=0;i<=y;i++) { x*=x; } return x; }
What type of a variable is used to indirectly return multiple results by a function?
To return multiple values of the same type, return an array. If the values are different types, return a tuple or data structure. To return values indirectly, return a pointer to the results (arrays implicitly convert to pointers, but tuples and data structures do not). A returned pointer must never refer to a local variable of the returning function; upon return, those variables will cease to exist, resulting in undefined behaviour. To avoid this, the caller may provide a user-defined storage location via an output argument, or the function may allocate the return values on the free store (the heap).
What are primitive variables?
Primitive variables are variables that are not objects and carry primitive values like numbers, boolean etc. The primitive data types in java are:intbytefloatcharlongbooleanshortdouble
What is a monotonic transformation and how does it impact the relationship between variables in a mathematical function?
A monotonic transformation is a mathematical function that preserves the order of values in a dataset. It does not change the relationship between variables in a mathematical function, but it can change the scale or shape of the function.
What set of all values that a function can take as is called domain of the function?
Actually, the set of all values that a function can take is referred to as the "range" of the function, not the domain. The domain of a function is the set of all possible input values (or independent variables) for which the function is defined. In contrast, the range consists of all output values that result from applying the function to its domain.
What are the input values of a function called?
variables
The domain of a function is repersentative of which one of the following characteristics of the function?
The domain of the function means, for what values of the independent variable (input value) (or variables) is the function defined. If you have an equation of the type:y = f(x) ("y" somehow depends on "x") then the domain is all the values that "x" can take.
What do the domain and range represent?
The domain of a function represents all possible input values (or independent variables) for which the function is defined, while the range represents all possible output values (or dependent variables) that result from those inputs. In simpler terms, the domain includes the x-values, and the range includes the corresponding y-values generated by the function. Understanding the domain and range is crucial for analyzing the behavior and limitations of functions.
How do you define function in php?
A function is defined in php by placing the keyword function before the chosen function name.The function name must not match a pre-defined function and has certain limitation as to the characters that can be part of it. Notably, the function name must not contain any spaces. Following the function name are a parenthesis-enclosed, comma-separated list of variables, these variables are called calling parameters and are helpful if the function must process some values or follows diferent branches depending on external variables. Finally the function body is enclosed in curly brackets { }.
The set of independent variables of a function is the?
The set of independent variables of a function is the input values that can be freely chosen or manipulated to calculate the corresponding output values. These variables are not dependent on other variables within the function and are usually denoted by symbols such as x or t in algebraic expressions.
Can continuous variables assume a limited number of values between any 2 specific values?
Yes, if you have two limiting variables with other possibles variables between them, the variables between the limiting variables would be continuous.
Which term best describes the set of values that a function will accept as inputs?
The term that best describes the set of values that a function will accept as inputs is the "domain." The domain includes all possible input values (or independent variables) for which the function is defined. Understanding the domain is crucial for determining the valid inputs that can be used in a function without leading to undefined situations.
What are limits in maths?
Limits (or limiting values) are values that a function may approach (but not actually reach) as the argument of the function approaches some given value. The function is usually not defined for that particular value of the argument.
How can you find the domain and range of a function?
The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.
What are the three common elements of an optimization problem?
The three common elements of an optimization problem are the objective function, constraints, and decision variables. The objective function defines what is being optimized, whether it's maximization or minimization. Constraints are the restrictions or limitations on the decision variables that must be satisfied. Decision variables are the values that can be controlled or adjusted to achieve the best outcome as defined by the objective function.
