- c++ The function in the code snippet above is incomplete, and at least 4 more statements are required to finish it. Show the full code for the function and explain any changes to the code excerpt concisely.C++ The function prototype of a function that recieves two integer values and computes their sum and difference is given as follows: void computeSum (int num1, int num2, int & sum, int & diff); write the statments to call this function to compute and print the sum and the differnce of 167 and 84.Playing with Functions: Write a Javascript program to check if the argument passed to any function is a function type or not. I.e. Create a function check which takes a argument and check if that argument is a function or not.
- 3. Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is smaller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver(i.e. a main() invoking your function).void getChar(char& c, istream& infile, int& i){ infile.get(c); if (c == '\n') i++;} COULD YOU REWRITTE THE FUNCTION ABOVE. AND BY REWRITE. I MEAN CHANGE THE FUNCTION NAME, PARAMETERS, AND ITS IMPLEMENTATION. HOWEVER, THE FUNCTION MUST STILL ACHEIVE THE SAME GOAL.Function definition: Double down Complete the DoubleDown function to return twice the initial Value.
- Look at the following function header:def my_function(a, b, c):Now look at the following call to my_function:my_function(3, 2, 1)When this call executes, what value will be assigned to a? What value will be assigned to b? What value will be assigned to c?Please fill in the blanks for the following statements: The ________________ statement passes a value back to a function’s caller.Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
