What happens when I use the wrong format specifier?

Question

Just wondering what happens when I use the wrong format specifier in C?

For example:

x = \'A\';
printf(\"%c\\n\", x);
printf(\"%d\\n\", x);

x = 65;
         


        

Answer 1

since x is A, the first print f will print: 'A'.

The second will print the ascii value of A (look it up).

The 3rd one will print the ascii character for 65 (I think this is A or a, but its a letter).

The fourth one will print 65.

The 5th one will print 128.
