Note 1 at the front it represents negative number - (remember this for later), flip these bits and you get 01000111 So when you convert from int (32 bit long) to char (8 bit long) you basically discard all but most right 8 bits. When you convert this into decimal you will have -72. Because char is only 1 byte last 8 bits represent saved number in char variable and that is 10111000.

Numbers in C are represented as signed and that means first bit from the left is for sign (positive, negative) and the rest is number in full complement. Integer uses 4 byte and char uses 1 byte. That allows us to conclude that it is indeed plausible that your implementation converts int to char by keeping only the least-significant bits, and interpreting them as 8-bit two's complement. The arguments are promoted from char to int, and since int can represent all values of type char, that one is value-preserving. There is then an additional conversion when you call printf(). Among the possibilities is that the least-significant CHAR_BIT bits of each assigned value are stored in the target variable.
neo4j-remote/neo4j-remote-graphdb-0.9-1.3.( 205 k) The download jar file contains the following class files. The new type is signed and the value cannot be represented in it either the result is implementation-defined or an implementation-defined signal is raised.Įvidently no signal was raised, so the result is implementation-defined. Download neo4j-remote-graphdb-0.9-1.3.m01.jar. Supposing, however, that your chars are signed, which indeed seems consistent with your results, the C rule for the conversions implicit in the assignment statements will not satisfy you: On implementations where char is unsigned, 250 is within its range. That is left to implementations to decide, and they are not consistent on that. Note first that C does not specify whether char is signed or unsigned. Please explain the integer to char conversion rule applied here as both 3000 and 250 are outside the range of char(-128 to 127).
