Problem 1 Write a program that finds the first non-repeated char in a string. That is the first char from left to right that does not exist twice in the string. The program should be repeated until the user enters quit". Introduce functions to improve your code clarity Find First Non-Repeated Char 10 points For example, a user inputs the string "Hello", the program would print out H and index 0 as this is the first char that does not exist twice in the string. If the character is not found in the string, the program outputs "Not found". Hint: Use a string just like a char array. You may use the length0 function of a string variable
