hello
I,ve wrote a program but it doesn,t work correctly
please help me
i want to sort some strings based on the number that should be entered at first of each string for example the strings that you enter should be in this form:
12_hello
it means you should enter a number and then _ then a string
for example if you enter
5_allow
4_how
23_hi
the output should be
4_how
5_allow
23_hi

but my program can't do this
i will write my program here

please correct it for me
thanks in advance

nobody wants to help me?

Don't bump the thread. People will help you when they are ready.

You're on the right track though, you've tokenised the original string splitting it into two parts. Then you are sorting the string according to its integer. I'll have a look at it later.
