Question

   

#include<stdio.h>
int main()
{
   int a = 15;
   printf("%d\n",++a);
   printf("%d\n",a++);
   printf("%d\n",--a);
   printf("%d\n",a--);
   return 0;
}

• A. 16,16,16,16
• B. 15,13,15,15
• C. 16,15,14,14
• D. 16,16,14,14

Comments

Option a) is correct

Intiallly a= 15

1) Increment a and prints it : 16

2) Prints a: 16 and increment it: 17

3) Decrement a: 16 and prints it : 16

4) Prints a: 16 and decrement it : 15
