What is the output of the following C program

#include<stdio.h>

int main () {

int shifty;

shifty = 0273;

shifty = shifty >>4;

shifty = shifty <<6;

printf("the value of shifty is %o",shifty);

return 0; }

• the value of shifty is 5447

• the value of shifty is 0273

• the value of shifty is 1300

• the value of shifty is 2600

Given that x=-8.5, j=3.0, n=2.0, m=-2.0

the value of - - x + j == x>n> = m is:

• 0

• -1

• 3

• 2

#include <stdio.h>

int main() {

int i = 7;

printf("%d", (++i)++);

return 0;}

What is the output of the above program?

• 7

• 8

• 9

• Compile time error

Assume that the size of an integer is 4 bytes, predict the output of following program.

#include <stdio.h>

int main() {

int i = 14;

int j = sizeof(i++);

printf("%d %d", i, j);

return 0; }

• 15 4

• 14 4

• 0 4

• Compiler error

int main() {

int i;

if(printf("0"))

i = 3;

else i = 5;

printf("%d", i);

return 0; }

Predict the output of above program?

• 3

• 5

• 05

• 03

int main() {

int a = 5;

switch(a) {

default: a = 4;

case 6: a--;

case 5: a = a+1;

case 1: a = a-1; }

printf("%d", a);

return 0; }

What is the value of a?

• 6

• 5

• 3

• 4

"GcetQuiz" displayed howmany times for the given code?

int main() {

int i = -5;

while (i <= 5) {

if (i >= 0) break;

else { i++; continue; }

printf("GcetQuiz");

}

return 0; }

• 10 times

• 0 times

• 5 times

• 4 times

• Infinite times

int main() {

unsigned int x = -1;

int y = ~0;

if (x == y) printf("same");

else printf("not same");

return 0; }

• same

• not same

Assume that the size of char is 1 byte

int main() {

char c = 135;

c = c+7;

printf("%d", c);

return 0;

}

What is the value of c?

• 135

• +INF

• -114

• -8

int main() {

int i;

for( i=1; i<5; i++ ) {

int i = 7;

printf ( "%d ", i );

i++;

}

return 0; }
