The expression UChar( c ) converts to unsigned char in order to get rid of negative values, which, except for EOF, are not supported by the C functions. Then the result of that expression is used as actual argument for an int formal argument. Where you get automatic promotion to int.
int length = 10; char len = length + '0'; printf("%c", len); This gave me : for 58 on the ascii chart not 10 that I wanted.
int search_book(){ int select_search; char dumpchar[30]

int a = 65; char c = (char) a; Note that since characters are smaller in size than integer, this casting may cause a loss of data.
Here, we used '0' because chars are actually represented by ASCII values. '0' is a char and represented by the value of 48. We typed (a + '0') and in order to add these up, Java converted '0' to its ASCII value which is 48 and a is 1 so the sum is 49. Then what we did is
Сделать преобразование unsigned char в char, а затем типу int Здраствуйте, есть вопрос: Число представлено двумя полями: типа long для
I can of course access each char by index, but how do I convert it into an int? I've looked into atoi(), but it takes a string as argument. Hence I must convert each char into a string and then call atoi on it.
