This is not a graded question so please don't disregard it as if it is. Thank you in advance professor!

Extracted text: Write the function int charErase (char str[U, int pos []); that receives a string str and a vector of integers without repeated values pos and modifies the string str by deleting all the characters that are in the positions indicated by pos. The cancellation and compaction must be done directly on str. The vector pos has an unknown size, but it contains the value -1 as the last element. The function returns, as an integer, the number of deleted characters For example, if the string str is ThisIsAString and pos contains 7,4,2,0,11,-1 the function should delete from str the characters S, I, i,T,n and return the value 5, modifying the string as follows: hssAtrig
