Why does printf implicit float to int conversion not work?

Question

Please help me in understanding the following C Output:

#include
int main() {
    float x = 4.0;
    printf(\"%f\\n\",x);
    printf(\"%d\\n\",x);         


        

Answer 1

You're not printing y, you're printing x again.

As a side note, printf can't do conversions. So passing a float when a %d is expected is undefined behavior.
