1-4 Exercise 1: String compare function

0 like 0 dislike
12k views

Each string will have two strings (string A and string B), each sub-string has 5 characters. 

Write a program with a function compare(string A, string B) for comparison

輸入兩個字串(string A, string B), 每個字串有五個字元

寫一個compare(string A, string B)函數。不能用字串函式庫

If String A == String B returns 0

If string A> string B returns 1

If string A <string B returns -1

Do not use string libraries

Example input:

gamesbegin

Example output: (because g>b => 1)

1

Example input:

iamigiates

Example output: (because m<t => -1)

-1

 Example input:

111qq111qq

Example output:

0

Remember: You may correct the cases, but your code always be revised!
