将整数转换为字符，反之亦然

Question

How to convert integer to char and vice versa in "Dynamic C".

Use VB.NET as bellow:

Dim i As Integer
Dim c As Char

' Integer to Character
i = 302
c = ChrW(302)
Debug.Print(c)  'Result: Į

' Character to Integer
Dim j As Integer
j = AscW(c)
Debug.Print(CStr(j))  ' Result: 302

Thanks

Answer 1

Since both int and char are integer types, you can simply assign an appropriately-valued integer to a char and vice versa:

int i = 65; // 'A'
char c = 'B'; // 66;
int cAsInt = (int)c; // 66 = 'B'
char iAsChar = (char)i; // 'A' = "65"

Answer 2

If you want to parse a character such that '1' becomes the integer 1, you can use itoa and atoi .

If you want to convert between the the ascii values and their characters, that's even easier. Simply cast the int to a char or the char to an int.

Answer 3

Why dont you use an other type like uint16_t that can be used for UCS2 ? I mean char is used for ascii and extended 0-255 ~ uint8_t, if you need more dont use char.

uint16_t c=302;
