C++ Sorting an Array in Alphabetical order using strcpy and strcmp while taking data from a file?

Question

I almost have it working however, it is seperating the last names that start in caps and the ones that do not.

Example file

LastName FirstName DaysofRental BalanceDue

Smith Joe 15 100.50

Doe John 10 95.20

Anderson Paul 30 20.00

O'Donell Miriam 10 24.30

Foster Sam 30 15.00

Zom Pete 10 20.00

Mock Chilly 100 30

smitty Chris 200 200

xu Conor 1 200

anilo steve 0 0

What "Sorted" file is outputing

LastName FirstName DaysofRental BalanceDue

Anderson Paul 30 $20.00

Doe John 10 $95.20

Foster Sam 30 $15.00

Mock Chilly 100 $30.00

O'Donell Miriam 10 $24.30

Smith Joe 15 $100.50

Zom Pete 10 $20.00

anilo steve 0 $0.00
smitty Chris 200 $200.00
xu Conor 1 $200.00

Answer 1

Use if (strcmpi(last[count2], mname) < 0); for the comparison, instead of if (strcmp(last[count2], mname) ==-1);

strcmpi() functions same as strcmp() but it is not case sensitive.

Also add exit(1) if ifstream in fails to open.
