Problem A. Character array, char, number systems (35pts) 1.1 Specification As we all know, Standard library defines a library function atoi. This function converts an array of digit characters, which represents a Decimal integer literal, into the corresponding decimal integer. atoi does not handle Oct and Hex literals correctly. Here you are going to implement an extended version of atoi called my_atoi, which does the same conversion for Decimal literals but also converts Octal (base 8) and Hex (base 16) Integer literals. For example, given char array "012" the function returns integer 10 whereas given char array "0x18" or "Oxib", it returns decimal value 27. (atoi will return for both). 1.2 Implementation Download the file myatoi.c to start off. Eeach input is assumed to be a valid Decimal integer literal such as "125" or a valid Octal integer literal which starts with O and contains digit 1-7, such as "0125", or a valid Hex literal which starts with ox or 0x and contains digits 0-9 and letters 'A' and 'a'. 'f' only. For each input, the program first prints it as a string, and then call atoi and my_atoi to convert it, and then outputs its numerical value in Decimal, Octal, and Hex, followed by double the value and square of the value (implemented for you). The program keeps on reading from the user until quit is entered. Note: Apparently, you should not callatoilinmy_atoi(). . In my_atoi (), you also should not call other functions declared in
, such as atoll), atof(), strtolo, strtoul(). Inmy_atoi (), you also should not call library functions declared in , such as sscanf(), fscanf(). You are free to use other library functions. Remember that if you use math library functions and you compile your program in the lab environment, you need to use -Im flag of gcc. 1.3 Sample Inputs/Outputs (note that atoi doesn't handle Octal and Hex literals correctly). red 127 } a.out Enter a word of positive number or 'quit': 4 4 atoi: 4 (04, 0X4) 8 my_atoi: 4 (04, 0X4) Enter a word of positive number or 'quit': 5 5 atoi: 5 (05, 0X5) my_atoi: 5 (05, 0X5) 10 16 16 8 10 25 25
