To convert int to a string using snprintf(), again, include the necessary header: #include <stdio.h> Declare an integer variable and a character array (string) to store the converted value: int num; char str[20]; The int num will store the integer value we want to convert, and st...
If the value p being boxed is true, false, a byte, a char in the range \u0000 to \u007f, or an int or short number between -128 and 127, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2. ...
