The text output of a program should be well-formatted for readability as well as displayingnumbers with the proper notation and precision levels. The default output formatting in C++ isoften not desirable, so one can add explicit instructions to the cout stream. These manipulatorsand functions are defined in the library.O setw (n): set the width (number of characters) of the next item to be at least n.• If the next item width is less than n, then pad the item with extra spaces.• If the next item width is greater than n, then the entire next item is output.• left and right: when used in conjunction with setw (), justify the item to one sideforcing the padding to the other side. Note that these manipulators are persistent, i.e. remainseffective until the next change occurs.• fixed: use the fixed-point notation (the decimal point notation that we are familiar with)when displaying a numerical item. Note that fixed defaults to 6 decimal points if the datatype is float or double. See the example below:int i = 123;float f = 12.3;float ff = 0.0001234;double d = 10;ble dd = 20.123456789o;cout << £ixed;cout << i < endl;sout << E << endl;Note theroundine// output: 123// output: 12.300000// output: 0.000123// output: 10.000000// output: 20.123457cout << EEcut << d << endl:endl;Note theroundingcout << dd << endl;• setprecision (n) : when used in conjunction wvith fixed, set the number of digits afterthe decimal point to n. Without fixed, the setprecision (n) will output n sigmificantdigits instead.• showpoint: when printing a floating-point mumber, display the decimal point even if thevalue is exactly equal to a whole number.For setw (), setprecision (), showpoint, see example below:float cost = 10.0;cout << ":" < cost < ":" << endl;cout << fixed << setprecision (2) < showpoint;cout << right << ":" << setw (8) << cost << ":" << endl;cout << ":" << setw(8) << "1234567" << ":" << endl;The output would be as follows::10:10.00:: 1234567: Assuming there are no deposits other than the original investment, the balance in a savingaccount after one year may be calculated asRateAmount = Principal x (1+%3DT.Principal is the balance in the savings account, Rate is the nterest rate, and Tis the number oftimes the interest is compounded during a year (e.g Tis 4 if the interest is compoundedquarterly).

Write a C++ function named dup that makes a copy of a user input C-string and repeats the C-string. For example, if the user inputs "HelloWorld" then it will say "HelloWorldHelloWorld" Dynamically allocate memory *(using new)* for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character! Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you wish, but you are not required to. Please demonstrate calling this function. Example: dup("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "GiantsGiants" char* dup(char *str)
Can you write a new code in C ++ language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file. All of the results will be printed to the file. There will be no screen output. Sample output is shown in Figure 1.

Write a function-based C++ program that reads words and numeric values from an input file. Your program should separate all words into a file named “words.txt” and numeric values into another file named “numeric.txt”. Example: Input File Mid exam of PF Lab Spring 2021 is held on 8 may 2021 words.txt Mid exam of PF Lab Spring is held on may numeric.txt 2021 8 2021
Write a python program which contains a user-defined function called 'input_data'. This function should have a try/except block in it that will attempt to input a list of three players' last name and their associated number. For example, 'Jones', 44 would be one such pair of data. These name/number pairs should be added to the list, with the name first, and the number following. The list should be returned by the function. If there is an error inputting the names, the except block should set the player names to 'none', 0 for all three cases. Then, in a separate python program, take this function and place it into a loadable module called module1. Write a program that imports module1 and calls the function, then prints the string returned by the module.
Write a C++ function named dup that makes a copy of a C-string but repeats the C-string. For example, if your C-string contains "bye" the result should be "byebye". Here is what it should do: Dynamically allocate memory (using new) for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character! Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you wish, but you are not required to. You do not need to demonstrate calling this function. Example: dup("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "GiantsGiants" char* dup(char *str)
(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

in c programing Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 The program must define and call the following two functions. Define a function named IntToReverseBinary that takes an int named integerValue as the first parameter and assigns the second parameter, binaryValue, with a string of 1's and 0's representing the integerValue in binary (in reverse order). Define a function named StringReverse that takes an input string as the first parameter and assigns the second parameter, reversedString, with the reverse of inputString. void IntToReverseBinary(int integerValue, char binaryValue[])void StringReverse(char…
While statements may start and stop anywhere in the flexible manner popularized by Algol60, most modern programming languages insist that statements finish with an end sign like a semicolon or colon. To the contrary, Python and a handful of other programming languages adhere to a set structure in which statements start in a certain column and stop at the end of a line of code unless continuation marks are provided for each statement. Discover how readability, writability, and security are affected by a file's fixed or free format in the following paragraphs.
