The istream and ostream classes work with chars, rather than wchar_ts, and won't interpret wide chars correctly. However, changing them to work with wchar_t would break a large amount of existing code, so they have to be retained for backwards compatibility. Naturally, the standards commitee wanted to provide a portable solution to this, and to this end, the standard now defines wistream and wostream classes, and mirror objects for the standard input and output: wcin and wcout. To work with wide chars, you will want to use those instead of cin and cout.
after more search i found it ;)
here i use 'en_US.UTF-8' string option, but we can change it for other types
> The setlocale function installs the specified system locale or its portion as the new C locale. The modifications remain in effect and influences the execution of all locale-sensitive C library functions until the next call to setlocale. If locale is a null pointer, setlocale queries the current C locale without modifying it.
> category - locale category identifier, one of the LC_xxx macros. May be 0.

Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
