You don't find the number of bits in the result of adding two values in a C program in the shell; you find that number in your C program. And, the number of bytes in the result of an addition depends on the sizes of the integers you are adding. Due to integral value promotion rules in C on a UNIX-, Linux-, or BSD-based operating system, the number of bits in the result of adding a and b will be the number of bits in the largest of the two values a and b. The number of bytes in a can be found with sizeof(a); and the number of bytes in b can be found with sizeof(b); and the number of bits in the result will be 8 times the maximum of those two sizes.
