C LANGUAGE QUIZ 7

1. What is the value of 'grade' after the switch statement is executed?

marks = 80;

switch (marks)

{

case 60:

grade = 'C';

break;

case 75:

grade = 'B';

break;

case 80:

grade = 'A';

break;

default:

grade = 'E';

}

2. What is the output of the following program?

3. Suppose a,b,c are integer variables with values 5,6,7 respectively. What is the value of the expression:
!((b+c)>(a+10))

4. What will be output of the following c program?
#include "stdio.h"
int main()
{
int _ = 5;
int __ = 10;
int ___;
___ = _ + __;
printf("%i", ___);
return 0;
}

5.Consider the following translation unit consisting of a global variable declaration:

struct foo x;

struct foo { int i; }

At the point of the declaration of variable x the structure type foo is incomplete. Thus the size is unknown. Only later on in the translation unit the type is completed. Is this translation unit legal?

6.Consider the following function where the type of parameter a as well as of local variable b is an array of 42 integers.

bool foo(int a[42]) {

int b[42];

return sizeof(a) == sizeof(b);

}

7. Find the output of the following program.

void main(){

int i = 01289;

printf("%d", i);

}

8.Assuming a short is two bytes long, what will be printed by the below code?

short exmarray[4] [3] = { {1}, {2, 3},  {4, 5, 6}};

printf("%d", sizeof(exmarray));

9. What is the output of the following program?

void xyz(int p1, int *p2){

++p1;

++*p2;

printf("%d%d",p1,*p2);

}

void main(){

int a=10;

xyz(a++,++*(&a));

xyz(a++,++*(&a));

printf("%d",a);

}

10.What is the output of following program?

void e1(){

static int a=5;

++a;

printf("%d",a);

}

main(){

e1();

e1();

}
