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

sizeof only works at compiletime to get the size of an expression.

The following wont actually increase 'c':

c = sizeof(++c);

The expression sizeof(a + b) will return the largest type with unsigned having precedence
