Discussion Forum : Expressions - Find Output of Program (Q.No. 11)
11.
What will be the output of the program?
#include<stdio.h>
int main()
{
int x=55;
printf("%d, %d, %d\n", x<=55, x=40, x>=10);
return 0;
}
Answer: Option
Explanation:
Step 1: int x=55; here variable x is declared as an integer type and initialized to '55'.
Step 2: printf("%d, %d, %d\n", x<=55, x=40, x>=10);
In printf the execution of expressions is from Right to Left.
here x>=10 returns TRUE hence it prints '1'.
x=40 here x is assigned to 40 Hence it prints '40'.
x<=55 returns TRUE. hence it prints '1'.
Step 3: Hence the output is "1, 40, 1".

Ok I got it.
And I think think this ex. Will help others who are in doubt:
#include<stdio.h>
int main()
{
int x=55;
printf("%d, %d, %d\n", x>=55, x=40, x>160);
return 0;
}
And its output is:
0, 40, 0.

}
It's output is :-
1, 40, 0.
So how can you say that in printf the execution of expressions is from Right to Left.
int main()
{
int x=55;
printf("%d, %d, %d\n", x<=55, x=40, x>160);
return 0;

main ()
{
int I;
I = (1,2,3);
printf( " % d ", I );
I=1,2,3;
printf(" % d ", I );
}
Output of this question?
{
int I;
I = (1,2,3);
printf( " % d ", I );
I=1,2,3;
printf(" % d ", I );
}
Output of this question?

But, there how if the condition is true means that will display 1 as output, can any one clear my confusion.

Yes, in printf the execution of expressions is from Right to Left. so first x>=10 is evaluated, which happens to be true so output of 3rd expression will be 1. now in the middle one, x is assigned the value of 40, and the final leftmost expression asks whether x<=55, which is true as the new value of x is 40.
This should be the way of evaluation of expressions in the answer.
Either way the answer turns out be 1,40,1.
