what will be the output b=3; a=b++;

[megha barde]

when the following piece of code is executed,what happened?
b=3; a=b++;

[PreethiGowri]

b is with post-increment operator in this, Post-Increment value is first used in a expression and then incremented.
Consider an example say,

#include<stdio.h>

void main()
{
int a,b=3;

a = b++;
printf("Value of a : %d",a);
a = b++;
printf("Value of b : %d",a);
}

output :
Value of a : 3
Value of b : 4

Whenever you want to see the outcome of a piece of code, just write a small program and run it.

A quick summary of terminology. The expression b++ invokes the post-increment operation. C has several variations:

• b-- post-decrement
• ++b pre-increment
• --b pre-decrement
