Homework Answers
- An expression such as pow(2,3) is called a function call.
Explanation: Function calls are used to invoke the function definition by passing arguments.
Here, 2,3 are arguments to the function pow().
- Which header file contains the sqrt function? cmath.h
Explantion: cmath.h is a header containing functions prototypes for mathematical operations.
sqrt() is used to find the square root of a number.
Some other functions are exp(),cos(),sin(), log(),pow()
- Which header file contains the setFill function? iomanip.h
Explantion: iomanip.h is a library for output formatting .
setFill() is used to fill the output stream with a character.
Some other functions are setw(),setiosflags()
- Which header file contains string functions? string.h
Explantion: string.h is a library for string functions .
Some functions in string.h are strcat(),strncat(),strcmp(),strcpy()
- What is the syntax of the ignore function? cin.ingnore(streamsize,delimiter)
Explantion: cin.ingnore(streamsize,delimiter)
- The get function presented in this chapter only reads values of type character.
- Write a statement to format the output of decimal numbers to two decimal places.
std::cout<<std::fixed<<std::setprecision(2);
Explanation: std::fixed - is used used to apply setprecision() to floating part of the decimal
std::setprecision(2) - is used to set the precision to two decimals.
- To force the output to show the decimal point and trailing zeros of a decimal number, use the showpoint manipulator.

In C program Consider a file that contains employee records, called "empstat.txt." The data for each employee consist of the employee’s last name (up to 20 characters), employee id number (up to 11 characters), gross pay for the week (double), taxes deducted (double) for the week, and net pay (double) for the week. Create a struct to hold the employee information. Write a void function called writeEmpFile that prompts the user to enter last name, id number, gross pay and...

1) String format checker A string is referred to as A"B"A" if it contains n > 0 consecutive As followed by n consecutive Bs followed by n consecutive As. Your task is to accept an arbitrary string of any length 1 <k, and determine if it is of the form A"B"A" If it is, then the output of the program is be "Format is OK". Otherwise the output is "Format not acceptable." For example, The given the Linux prompt>...

Problem1: BMPmain.c, BMPfns.c, BMPfns.h, Makefile The file 'BMPmain.c' contains a main() function which is already written for you and attached with this homework. When appropriate functions are provided, main() will create a .bmp image file. Your job is to write 'BMPfns.c' which contains the functions which main() uses to create .bmp image files. You must also write the header file 'BMPfns.h' to #include in BMPmain.c and which contains prototypes of the functions defined in BMPfns.c . Problem2: BMPcheckerboard.c, BMPfns.c, BMPfns.h,...

Problem: Create a program that contains two functions: main and a void function to read data from a file and process it. Your main function should prompt the user to enter the name of the file (Lab7.txt), store this name, and then call the function sending the name of the file to the function. After the function has completed, the main function should output the total number of values in the file, how many of the values were odd, how...

Write a program that loads a file called "sample.txt" in read mode, reads its content, and closes the file. Use exception handling to catch any errors. 2. Compute the letter and punctuation distribution in the file. That is, output the number of a’s, the number of b’s, etc. and the number of commas, dashes, and periods. Ignore case when computing this, so ‘A’ and ‘a’ are the same letter. Use lists. 3. Compute the number of words in the file....

Write a python function score_formatter() that takes one parameter, which is a formatted string that contains information about the score received by a student in a particular subject. The function analyzes the string and returns a reformatted string for the score. You will need to use the function re.sub that is discussed in the lecture notes. If the string does not match the pattern, the function returns the string "error". The input string is always given in the format specified...

Here you'll write the inorder traversal function in the header file "bst.h". Notice that the public inorder function calls a private recursive function _ inorder to do the actual traversal. This public-private strategy is the correct way to implement recursive functions, where the public function kicks off the recursion and the private function does the actual work. The public function is written for you, your job is to implement the private _ inorder function. he main program has been written...
