Converting an int into a 4 byte char array (C)

Question

Hey, I\'m looking to convert a int that is inputed by the user into 4 bytes, that I am assigning to a character array. How can this be done?

Example:

Answer 1

The problem is arising as unsigned char is a 4 byte number not a 1 byte number as many think, so change it to

union {
unsigned int integer;
char byte[4];
} temp32bitint;

and cast while printing, to prevent promoting to 'int' (which C does by default)

printf("%u, %u \n", (unsigned char)Buffer[0], (unsigned char)Buffer[1]);
