#include <stdio.h>
void fun(char *p) {
if (p) {
printf("%c", *p);
p++;
}
}
int main() {
fun("Y32Y567");
return 0;
}
Output:Y
Expected Output:Y32Y567
My questions why it is not working the expected way?

The function fun only prints one character if it enters the if. You probably meant to use a while loop, not a single if condition. Additionally, your condition is wrong - p evaluates to a true-thy as long as it's not NULL, which won't happen if you passed a string literal. You probably meant to test *p, i.e., the character p points to:
void fun(char* p)
{
while (*p) /* Here */
{
printf("%c",*p);
p++;
}
}
