I got the following errors. How do I fix them?

My code so far is as follows:

#include #include const float POUND = 1.31; const float YEN = 0.0091; const float RUPEE = 0.014; const float EURO = 1.11; char c; int currValue; float exchangeValue; float finValue; int printValue;

Your converter should understand dollars ('S'), Euros (''), British pounds sterling (''), the Japanese Yen (''), and the Indian Rupee ('5'). This should reuse code from your previous project. Your program should ignore any amount of white space between currency values, including tabs, spaces, newlines, etc. See the isspace() function in your text or in the man pages for details. However, your output should place each currency value on a line by itself. When the end of input ("EOF") is reached, the piles should be printed in order of dollars, British pounds sterling, Japanese Yen, Euros, and finally Indian Rupees. To store an arbitrary list of integers, your program will need to request more memory from the operating system when the space it already has runs out. This kind of dynamic allocation is performed using the malloc() function, as detailed in your text and in the man pages. You may assume that we will test your program with at least 100,000,000 integers. Your program should exit gracefully if a malloc() request is denied
