Discussion Forum : Expressions - Yes / No Questions (Q.No. 1)
1.
Are the following two statement same?
 1 a <= 20 ? (b = 30): (c = 30); 2 (a <=20) ? b : (c = 30);
Yes
No
Explanation:

No, the expressions 1 and 2 are not same.

1. a <= 20 ? (b = 30) : (c = 30); This statement can be rewritten as,

``````
if(a <= 20)
{
b = 30;
}
else
{
c = 30;
}
``````

2. (a <=20) ? b : (c = 30); This statement can be rewritten as,

``````
if(a <= 20)
{
//Nothing here
}
else
{
c = 30;
}
``````

@Vydehi.

a< = 20.
It works without parenthesis.

1. a <= 20 ? (b = 30):(c = 30);

In above there should be parenthesis for condition((a<=20)). Otherwise it is syntactically wrong.

Let me give an example to the above problem.

#include<stdio.h>
int main()
{

int a,b,c;

a = 11, b = 22 , c = 33;
a <= 20 ? (b = 30): (c = 30);
printf("\n b = %d, c = %d", b, c);

a = 11, b = 22 , c = 33;
(a <=20) ? b : (c = 30);
printf("\n b = %d, c = %d", b, c);

return 0;
}

// ouput:
b = 30, c = 33
b = 22, c = 33

Therefore, the given statements are not doing the same thing.
