Operators and Expressions MCQs

Find the output of the following program.

#include<stdio.h>
void main()
{
   int y=10;
   if(y++>9 && y++!=10 && y++>11)
      printf("%d", y);
   else
      printf("%d", y);
}

Find the output of the following program.

#include<stdio.h>
void main()
{
   int y=10;
   if(y++>9 && y++!=11 && y++>11)
      printf("%d", y);
   else
      printf("%d", y);
}

Determine output of the following program code.

#include<stdio.h>
void main()
{
   int a, b=7;
   a = b<4 ? b<<1 : ++b>4 ? 7>>1 : a;
   printf("%d %d", a, b);
}

Choose the correct output for the following program.

#include<stdio.h>
void main()
{
   int a=10, b=11, c=13, d;
   d = (a=c, b+=a, c=a+b+c);
   printf("%d %d %d %d", d, a, b, c);
}

Consider the following program fragment, and choose the correct one.

void main()
{
   int a, b = 2, c;
   a = 2 * (b++);
   c = 2 * (++b);
}

Which operator from the following has the lowest priority?

Identify the correct output of the following code:

void main()
{
   int w=10, x=5, y=3, z=3;
   if( (w < x ) && (y=z++) )
      printf("%d %d %d %d", w, x, y, z);
   else
      printf("%d %d %d %d", w, x, y, z);
}

Given b=110 and c=20, what is the value of 'a' after execution of the expression a=b-=c*=5?

what will be the output when following code is executed?

void main()
{
   int a=10, b;
   b = a++ + ++a;
   printf("%d %d %d %d", b, a++, a, ++a);
}
