Answer 1

#include <stdio.h>

void martian(int ch){
    printf("%c" ,ch);
    return;
}

int main()
{
    int md= 0x45;
    martian(md);
    return 0;
}

E

HEX DIGIT		DEC VALUE	MULTIPLICATION	RESULT
5		5	5 * 160	5
4		4	4 * 161	64

Add together all products

5 + 64 = 69

So, 0x45 in decimal is 69

ASCII value for decimal 69 is E

So, output of code is E

In other words, ASCII value for hex 0x45 is E, So code prints E
