Tr command using C language

We know the tr command allows you to replace or translate characters in of a stream. It takes in two arguments - a set of characters to be replaced and a set of replacement characters. The full functionality of the command can be found using man tr, but this problem only requires a basic implementation capable of solving the examples below. Write a program that implements basic tr functionality. Your program should take two arguments - the set of characters to be replaced and a set of replacement characters. It should then read lines of input from the standard in until EOF and translate them as shown in examples below. Example 1 $ ./tr abc def Input abc aabbcc aaabbbccc Output def ddeeff dddeeefff Example 2 $ ./tr xy XY Input xxyyxx Lorem ipsum dolor sit amet xxyyxx Output XXYYXX Lorem ipsum dolor sit amet XXYYXX
