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

The data type of a is "short int". -32768 ~ +32767

The data type of c is "char". 0 ~ 255

When you add a to c it is not either short int nor char, it becomes int!

Here is is an example code which help you to get the variable data type:

#include 

int main()
{
    short int a = 1;
    char c = 'A';
    std::cout << typeid(a + c).name() << std::endl;

    return 1;
}
