Question
Write a function with the following header to format a posi- tive integer with the specified width:
string format(int number, int width)
The function returns a string for the number with one or more prefix 0s. The size of the string is the width. For example, format(34, 4) returns 0034 and format(34, 5) returns 00034. If the number is longer than the width, the function returns the string representation for the number. For example, format(34, 1) returns 34.

- Given a double precision floating point number with a decimal point, write a function named prg_question 3 to return the whole number and decimal part of the number as a std::pair object of integers with first part being the whole number part and the second part being the fraction or decimal part. For example given the number 3.14, the "first" part of the pair object must be 3 and the "second" must be 14. Do the following: 1. Follow UMPIRE process to get the algorithm. Write only the algorithm as code comments 2. Implement your function 3. Test your function for numbers 3.14159 and 2.71828.

The return type is a str and it is the most commonly occuring color. If two colors are tied for popularity, the first color shown will be picked.arrow_forwardAn integer n is passed as argument to a function named convert0to5. This function returns an integer by replacing all 0's in the number by 5. Note: Do not convert the number to string.arrow_forward
- in C++ use this function to calcul the range: function range step Specified value of y y = 0.05*x3+6sin(3x)+4 From -2.5 to 2.5 0.5 -2 The program will calculate average value of y for the given range. To find the average, usestd::accumulate using algorithm header and divide by the number of elements. The output must be write with the result:Average value of function y for the given range is : ;arrow_forward[CelsiusTemperature Table] The formula for converting a temperature from Fahrenheit to Celsius is C = 5/9 * (F - 32) where F is the Fahrenheit temperature and C is the Celsius temperature.Write a function named celsius that accepts two Fahrenheit temperatures (low and high) as arguments. The function will print a table list the Fahrenheit temperatures from low to high and the corresponding Celsuis temperatures. What is the function prototype? (assume only integers used for the temperate) void celsius (int, int); How to implement this function? The function will use a loop to convert the Fahrenheit temperatures to Celsius temperatures and display the values in the console. In the driver program, prompt for the user input for the low and high Fahrenheit temperatures. Call the the function to display the result in the console. Requirements: Use only for-loop for this exercise; Print the output in a table format Include the function prototypes before the main() All functions…arrow_forwardPython Suppose scDict maps names to test scores. Print each name/score on a separate line Write a function calcStats that calculates and RETURNS the average, highest, and lowest of the scores. The function should NOT print anything.
