With C program code with flowchart please

Part 1.

Write a program named prices.c that repeatedly asks users to enter the price of an item until they enter zero. Prices less than zero will be ignored. The program will then print the number of items purchased, the subtotal of the prices, the sales tax charged (at a rate of 7.5%), and the grand total.

Your program must use a while loop or do/while loop.

Here is what a sample run of the program might look like. The cursor for user input must appear on the same line as the input prompt. All monetary values must be displayed with two digits to the right of the decimal point.

Part 2.

At the last US Census in 2010, the population was 308,401,808. To estimate population in non-census years, the Census Bureau uses these statistics (Links to an external site.): One birth every 9 seconds One death every 10 seconds One net international migrant every 47 seconds Write a program named population.c that prints a table of estimated population from 2011 to 2020 (inclusive). This program must use a for loop. Do all calculations using integer arithmetic. Hint: Find out how many people are born, die, and migrate per year. Presume there are 365 days per year. This is not a compound interest problem! Here is what your output might look like. To save space, I am showing only a part of the output. Your output does not have to look exactly like this, but it must reflect the same information. Your output must be labeled with a heading line.
