Discussion Forum : Expressions - Find Output of Program (Q.No. 12)
12.
What will be the output of the program?
#include<stdio.h>
int main()
{
int i=2;
printf("%d, %d\n", ++i, ++i);
return 0;
}
Answer: Option
Explanation:
The order of evaluation of arguments passed to a function call is unspecified.
Anyhow, we consider ++i, ++i are Right-to-Left associativity. The output of the program is 4, 3.
In TurboC, the output will be 4, 3.
In GCC, the output will be 4, 4.

printf("%d, %d", ++i, ++i)
Here arguments in fxn prnitf() are evaluated from right to left. It is a rule in C. And at time of printing they are displayed in the Left to Right basis.

How the output for the following produce?
#include<stdio.h>
int main()
{
int a=35;
printf("%d %d %d %d %d ",a++,a++,++a,a++,++a);
return 0;
}
OUTPUT gcc: 39 38 40 36 40.
#include<stdio.h>
int main()
{
int a=35;
printf("%d %d %d %d %d ",a++,a++,++a,a++,++a);
return 0;
}
OUTPUT gcc: 39 38 40 36 40.

What is the output and how did we get it? Can anyone help me please?
#include<stdio.h>
void main ()
{
int a = 3;
int b = ++a + a++ + --a;
printf ("Value of b is %d", b);
}
#include<stdio.h>
void main ()
{
int a = 3;
int b = ++a + a++ + --a;
printf ("Value of b is %d", b);
}

#include<stdio.h>
int main()
{
int a=35;
printf("%d %d %d ",a==40,a<=50,a=30);
return 0;
}
Please explain it clearly ....
o/p : 0 0 30
int main()
{
int a=35;
printf("%d %d %d ",a==40,a<=50,a=30);
return 0;
}
Please explain it clearly ....

Is associativity considered in the printf function also or only while evaluating an expression we consider the associativity ?
Can any one explain it. ?

OUTPUT ? AND WHY THAT O/P?
#include<stdio.h>
int main()
{
int i=2;
int j=3;
printf("%d, %d\n", ++j, ++i);
return 0;
}
#include<stdio.h>
int main()
{
int i=2;
int j=3;
printf("%d, %d\n", ++j, ++i);
return 0;
}

in turbo C o/p is 4,3.
in c++ o/p is 3,4.
in GCC o/p is 4,4.
Thus the answer will be option D : output will vary from compiler to compiler.

printf reads from right to left and if it is assigned value before and we again assigned value and we assigned in printf which value does it take.
