Question $1[5$ marks$]$

Write a function that replaces a specific digit in an int number with another digit and returns the result as

an int. Return the same number if the target$/$replacement character is not a digit. Use this function header:

int replaceDigits$($int number, char target, char replacement$)$

For example:

replaceDigits$(1,\text{'}1\text{'},\text{'}2\text{'})$ should return $2$

replaceDigits$(-232,\text{'}3\text{'},\text{'}0\text{'})$ should return $-202$

replaceDigits$(123,\text{'}4\text{'},\text{'}5\text{'})$ should return $123$

replaceDigits$(1223,\text{'}{?}^{\text{'}}\text{'},\text{'}?\text{'})$ should return $1223$

replaceDigits$(5670,{?}^{\text{'}}5\text{'},\text{'}0\text{'})$ should return $670($leading zero will not be part of the resulting number$)$

replaceDigits$(30400,{?}^{\text{'}}0\text{'},\text{'}9\text{'})$ should return $39499$

You can assume the number does not have leading zeros $($e$.$g$.,$ we will not call replaceDigits$(01,\text{'}1\text{'},\text{'}2\text{'})),$

except when the number is actually zero $($i$.$e$.,$ we might call replaceDigits$(0,\text{'}1\text{'},\text{'}1\text{'})).$

Only include the a$1\_$question.h header file and the function definition $($and your helper functions, if any$)$

in the source file and name it as a$1\_$question$1.$c$.$ Do not use recursion in your answer.

$**$ please ensure to comment what the important lines of code do$,$ code in the context of a first year intro to coding course, and only library you should use is stdio.h$,$ not others. Thanks! $<mn>3</mn>$
