I have two codes and two question.

Question about first code: Has an integer promotion been made? I mean, y–>Promoted int –>Double ? or y–>Double?

Question about second code: Has an integer promotion been made? I mean, x and y–>Promoted int?

//First code
#include <stdio.h>
int main() {
double x=17.123;
short y=13;
x+y;
    return 0;
}

//Second Code
#include <stdio.h>
int main() {
short x=17;
short y=13;
x+y;
    return 0;
}
