b) int < char > float
c) char < int < float
d) char < int < double
Step by step
Solved in 2 steps
- 1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.Program in C: Part A: Write the code that defines a struct called dog The following information must be kept in appropriate data types: the name of the dog (char array) the breed of the dog (char array) the wieght of the dog (double) Part B: Write a function called GetDogInfo that declares a temporary dog and fills the 3 data fields with user input (remember to prompt for input) return the filled dog (the function return type is dog) Part C: Write a main function with a function call to GetDogInfoin C Recreate the four examples uses of pointers that cover the following four cases: non-constant pointer to non-constant data, constant pointer to non-constant data, non-constant pointer to constant data, and constant pointer to constant data.
- 1. Mark the following statements as true or false. a. An identifier must start with a letter and can be any sequence of characters. (1) b. In C++, there is no difference between a reserved word and a predefined identifier. (1) c. A C++ identifier cannot start with a digit. (1) d. The collating sequence of a character is its preset number in the character data set. (2) e. Only one of the operands of the modulus operator needs to be of type int. (3) f. If ; and ;, then after the statement ; the value of b is erased. (6) g. If the input is 7 and x is a variable of type int, then the statement ; assigns the value 7 to x. (6) h. In an output statement, the newline character may be a part of the string. (10) i. In C++, all variables must be initialized when they are declared. (7) j. In a mixed expression, all the operands are converted to floating-point numbers. (4) k. Suppose . After the statement ; executes, y is 5 and x is 6. (9) i. Suppose . After the statement ; executes, the value of a is still 5 because the value of the expression is not saved in another variable. (9)(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.38. To pass a scalar variable by reference in C++, you need to include the ____ operator before the formal parameter’s name in the receiving function’s header. a. & c. $ b. * d. @ 42. A simple, or ____ variable, is one that is unrelated to any other variable in memory. a. scalar b. vector c. independent d. dependent 43. You may use an assignment statement or the ____ operator to enter data into an array element. a. comparison b. arithmetic c. extraction d. insertion 44. Each of the ____ (variables) in an array has the same data type. a.elements b.objects c.structures d.subscripts
- Function Implementation with Data Abstraction in C Programming 1. Create a new file and SAVE as MATHV1.H Define and Implement the following functions: int sum(int x, int y); - returns the computed sum of two numbers x and y int diff(int x, int y); - returns the computed difference of two numbers x and y. Make sure that the larger number is deducted by the smaller number to avoid a negative answer long int prod(int x, int y); - returns the computed product of two number x and y float quot(int x, int y); - returns the computed quotient of two numbers x and y. Make sure that the larger number is always the numerator and divided by the smaller number to avoid division by zero error. int mod(int x, int y); - returns the computed remainder of two numbers x and y using the modulo operator %2. Create another new file and save as MYTOOLS.H void center(int row, char str[]); /*centers text across the screen -calculate here for the center col using the formula col=(80-strlen(str))/2; -then use…c++ code Implement the following two functions void print(Point &p) : prints the details of the point. Note that 2D points and 3D points should be treated differently. double computeDistance(Point & p1, Point & p2) : computes the Euclidean distance between the two points, which equals to: Sqrt((x1-x2)2+(y1-y2)2) for 2D points, and Sqrt((x1-x2)2+(y1-y2)2+(z1-z2)2) for 3D points. Implement a driver program to test these two functions.PLEASE WRITE THIS IN C Please read the following: Has to have the two functions as stated below, and has to use pointer notation! Include two functions in your program, one which demonstrates the functionality using pointer notation and one which demonstrates the functionality using array indexing. The function prototypes are below: void copyArrayIndexWay(char * const newArray1, const char * const originalArray1); void copyPointerWay(char *newArray2, const char *originalArray2); char originalArray1[] ="COMP10120"; char originalArray2[] = "COMP10110"; Include relevant print statements to explain the difference between the two functions and provide a nice output with the results..
