What happens here? sizeof(short_int_variable + char_variable)

Question

#include 
 int main()        
{

           short int i = 20;

            char c = 97;

            printf(\"%d, %d, %d\\n\", sizeof(i), sizeof(c), s         


        

Answer 1

1) sizeof(i) ==> sizeof(short int) = 2

2) sizeof(c) ==> sizeof(char) = 1

3) sizeof(c + i [97+20]) ==> sizeof(int) = 4 // result in constant value which is int as default
