- Provide the function/module header in pseudocode and in C++ code for each of the following. Include comments that describe the parameters and return values (if a value is returned). Please dont define the function, just give the header or prototype and comments. Be sure to indicate if the parameters need to be passed by reference. a. Swaps two reals numbers. b. Calculates and returns the sales tax given the price and the amount of the tax rate (both as reals). c. Returns the concatenation of two strings. d. Performs a search of a string for a character and returns true if the character is found and false otherwise.Provide the function/module header in pseudocode or in C++ code for each of the following.

Returns the concatenation of two strings. d. Performs a search of a string for a character and returns true if the character is found and false otherwise.I know the concept of function and programming well so no need to explain all that. I want to know if I can call a function inside another function or not in c++? If yes, please provide precise and direct code.
- Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows:dB= log10P2/P1Where P2 is the power level being measured, and P1 is some reference power level. Write a c++ programe contain function that calculates the level. The function’s prototype is as follows:double dBCalculator (double P1, double P2);Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.Change this code in C to Create functions and function prototypes to replace each of thecalculator actions. Prototype each function above main and write thefunction (definition) below main.- The input by the user and output statement of each calculation shouldstay in main and not be moved to a function except the output forfunction “iseven” which should be done in the function.- Each function will accept the value(s) supplied by the user as parametersand return the result in a return statement (not a printf statementexcept for “iseven”).- The result returned by each function should be outputted by a printfstatement in main.- Create a function named display that contains: menu displaystatements, the user prompt to select an option, user input. Thisfunction should have no parameters and should return a character asthe option chosen by the user. ----------------------------------------------------------------------------------------------------------…Write a C# program to define a function that takes parameters and also returns something. Also, make a call to your function inside the main function. Note: The return type should not be void.
- The following questions refer to the skeletal C++ program shown below. (a) Assume that static scoping is used. List all variables, along with the functions in which they are declared, that are visible at Line 1 in the program. (b) Repeat part (a), but list the variables that are visible at Line 2. (c) Repeat part (a), but list the variables that are visible at Line 3. (d) Repeat part (a), but list the variables that are visible at Line 4. (e) Repeat part (a), but list the variables that are visible at Line 5. (f) Assume that dynamic scoping is used, and that main calls f1 which calls f2. (Assume that f1 calls f2 on Line 3.) List all variables, along with the functions in which they are declared, that are visible at Line 5 in the program. void f1(); void f2(); int a, b, c; int main() { int c, d; … // Line 1 } void f1() { int b, e; if (…) { int a, b; // Line 2 } … // Line3 } void f2() { int b, d; if (…) { int a, d; … // Line 4 } … // Line 5 } A sample…14. Create a functional program in C++ that takes a string as the parameter. The string will contain only digits and the function should replace all 0 in the string with 5 and return it. Also, test your function and attach the output in the word file.Write a C++ program based on the following requirements: -Function main will accept two numbers and operation symbol (+,-, * or /) from the user. -Function calculate () will receives the numbers and symbol and will perform calculations based on the symbol chosen. -The result will be returned to function main () and will be displayed. -The program will be repeated until the user chooses not to continue.
- The following question is related to C programming (struct and function) Task-1: Suppose you and your friends go to have breakfast in a restaurant. Each of you orders Paratha, Vegetable, and Mineral Water. Treat each of the ordered items as structures and each of the structures will have two properties which are: quantity and unit price. Each property of the structure will be taken as input from the user. After taking all the inputs calculate what is the total bill and also, take input from the user on how many people are there in total. Lastly calculate how much each person will have to pay and print it (Note: This value will be a float). Sample Input: Quantity Of Paratha: 25 Unit Price: 10 Quantity Of Vegetables: 5 Unit Price: 20 Quantity Of Mineral Water: 20 Unit Price: 20 Number of People: 6 Sample Output: Individual people will pay: 125.00 tk1. Create a C function getPrime( ) with one argument type of integer ,your function checks the integer number is prime or notWrite a C statement to accomplish each of the following tasks.a) Define variables sum and x to be of type int.
