Discussion Forum : Declarations and Initializations - Find Output of Program (Q.No. 7)
7.
What is the output of the program
#include<stdio.h>
int main()
{
int x = 10, y = 20, z = 5, i;
i = x < y < z;
printf("%d\n", i);
return 0;
}
Answer: Option
Explanation:
Since x < y turns to be TRUE it is replaced by 1. Then 1 < z is compared and to be TRUE. The 1 is assigned to i.

#include<stdio.h>
int main()
{
int x = 10, y = 20, z = 5, i;
i = x,y,z;
printf("%d\n", i);
return 0;
}
If you try the above code
step 1: = is having highest priority than ,
step2: i=10 will be initalized
step3: , operater will travell form left to right
So the out put will be 10.
int main()
{
int x = 10, y = 20, z = 5, i;
i = x,y,z;
printf("%d\n", i);
return 0;

i=x,y,z;
Because it is
Just like below..
i=x;
y;
z;
Because it is
Just like below..
i=x;
y;
z;

int x = 30, y = 20, z = 5, i;
i = x <y <z;
printf("%d\n", i);
return 0;
}
Please explain this program.

@Sai.
i=((30<20)<5); //in this (30<20) is false so it is assigned 0.
i=(0<5); //in this (0<5) is true so it is assigned 1.
i=1;
False=0, True=1
i=((30<20)<5); //in this (30<20) is false so it is assigned 0.
i=(0<5); //in this (0<5) is true so it is assigned 1.
i=1;
False=0, True=1

@Krishna,as per priority given to the operaters, '=' is having highest priority and the operator ' will move from left to right.
and given as i=x,y,z.
so,
i=x=10.
and given as i=x,y,z.
so,
i=x=10.

I am explaining my thought.
#include<stdio.h>
int main()
{
int x = 10, y = 20, z = 5, i;
i = x < y < z;
printf("%d
", i);
return 0;
}
here i=10<20<5
Now c compiler starts execution from left side.
that is 10<20 returns TRUE and TRUE < 5 means 0 < 5 which is TRUE means Ans is 1
