Nettet26. sep. 2012 · int x = (*p_to_a) [i]; Since [] has higher precedence than *, we must use parentheses to force the grouping of operators so that the subscript is applied to the result of the expression *p_to_a. Since the type of the expression (*p_to_a) [i] is int, the declaration is int (*p_to_a) [N]; Nettet12. nov. 2015 · int (string, [base]) function converts given string into decimal number, here base is optional where you can give any number, some examples are 2 = Binary number 8 = Octal number 10 = Decimal number 16 = Hexadecimal number But please note that the string you give should be a number in that base.

It returns an int with the nth and mth bytes of x swapped x is just a normal integer, set to any value. n and m are integers between 0 and 3. For example, let the hex representation of x be 0x12345678, n is 0, and m is 2. The last and 3rd to last byte are supposed to be switched (n = 78, m = 34). NettetYou can use the int class method int.to_bytes () to convert an int object to an array of bytes representing that integer. The following is the syntax –. int.to_bytes(length, …
