Discussion Forum : Expressions - Find Output of Program (Q.No. 8)
8.
What will be the output of the program?
#include<stdio.h>
int main()
{
int x=4, y, z;
y = --x;
z = x--;
printf("%d, %d, %d\n", x, y, z);
return 0;
}
Answer: Option
Explanation:
Step 1: int x=4, y, z; here variable x, y, z are declared as an integer type and variable x is initialized to 4.
Step 2: y = --x; becomes y = 3; because (--x) is pre-decrement operator.
Step 3: z = x--; becomes z = 3;. In the next step variable x becomes 2, because (x--) is post-decrement operator.
Step 4: printf("%d, %d, %d\n", x, y, z); Hence it prints "2, 3, 3".
