#include <stdio.h>

int main()

{

int x = 2, y = 0;

int z = (y++) ? y == 1 && x : 0;

printf("%d\n", z);

return 0;

}

• 0

• 1

• Undefined behaviour

• Compile time error

#include <stdio.h>

int main()

{

int x = 1;

int y = x == 1 ? getchar(): 2;

printf("%d\n", y);

}

• Compile time error

• Whatever character getchar function returns

• Ascii value of character getchar function returns

• 2

#include <stdio.h>

int main()

{

int a = 2; int b = 0;

int y = (b == 0) ? a :(a > b) ? (b = 1): a;

printf("%d\n", y);

}

• Compile time error

• 1

• 2

• Undefined behaviour

What will be the output of the following C code?

#include <stdio.h>

int main()

{

int y = 1, x = 0;

int l = (y++, x++) ? y : x;

printf("%d\n", l);

}

• 1

• 2

• Compile time error

• Undefined behaviour

#include <stdio.h>

void main()

{

int k = 8; int m = 7;

int z = k < m ? k++ : m++;

printf("%d", z);

}

• 7

• 8

• Run time error

• 15

#include <stdio.h>

void main()

{

int k = 8; int m = 7;

int z = k < m ? k = m : m++;

printf("%d", z);

}

• Run time error

• 7

• 8

• Depends on compiler

#include <stdio.h>

void main()

{

1 < 2 ? return 1 : return 2;

}

• returns 1

• returns 2

• Varies

• Compile time error

#include <stdio.h>

void main()

{

int x = 5; if (x < 1)

printf("hello");

if (x == 5)

printf("hi");

else

printf("no");

}

• hi

• hello

• no

• error

#include <stdio.h>

int x;

void main()

{

if (x)

printf("hi");

else

printf("how are u");

}

• hi

• how are you

• compile time error

• error

#include <stdio.h>

void main()

{

int x = 5;

if (true);

printf("hello

}

• It will display hello

• It will throw an error

• Nothing will be displayed

• Compiler dependent
