#define is a macro where preprocessor replaces all its presence with the value where typedef is a user defined data type

#define C 5

void main()

{

printf("%d",C);->here the  preprocessor replaces C with 5

}

typedef int x;

x a;

now x refers to integer datatype but name is user defined

Can someone explain the output of this code? and what (char*) is doing actually? #include<stdio.h> struct Ournode{ char x, y, z; }; int main() { struct Ournode p={'1', '0', 'a'+2}; struct Ournode *q=&p; printf("%c, %c", '*((char*)q+1)', '*((char*)q+2)'); return 0; }

X=2; Y=++x * ++x * ++x ; Printf("%d",Y); In the above question, we have to use the final value of x or it will be evaluated seperately and then multiplied. Ex: Y= 3*4*5; or Y=5*5*5;
