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); |
Answer: Option
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.
a< = 20.

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.
