Answer 1

Do you use a Chinese keyboard? In the line printf("%x"，&c); you're using what looks like a Chinese comma. Replace it with an ASCII comma. Also, main() should have int as return type

Gordon I think he's trying to print the address of the variable. So both %x and &c are correct (could also use %p)

Answer 2

1. int main not void main

2. , not ，

3. %d not %x

4. c not &c

Answer 3

printf("%d",c);

Answer 4

printf("%d",c); prints the value of the integer variable

printf("%x", &c); prints the hexadecimal representation of the variable's address

Answer 5

thanks for all the suggestions above
