What is the output of the below given code?

#include <stdio.h>
int main()
{
int j;
j = printf("Testbook TestSeries\n");
j = printf("%d\n",j);
printf("%d\n",j);
}

Match the following list:

What is the output of the below given code?

#include <stdio.h>
int main()
{
int a = 2;
int year = 2020;
char flag = 'a' + a;
switch(flag)
{
case 'a': printf("GATE CS %d ",year);           
case 'b':
case 'c': printf("GATE CS %d ",year + 1);
case 'd': break;
default: printf("GATE CS %d",year + 2);
}
return 0;

}

Consider the below given code in which integer is of 2 bytes?

#include <stdio.h>
void function(int *co, int *vid)
{
co = vid;
*co = 19;
}
int main()
{
 int p = 20, q = 19;
function(&q,&p);
printf("Co-vid %d%d", p, q);
return 0;
}

The output is Co-vid ____? (Fill in the blanks)

Which one of the following choices given below would be printed when the following program is executed?

#include<stdio.h>

void display(int *tb[]);

int main()

{

int array1[] = {2,5,8,12,6,9};

int array2[] = {-12, 4, 6, -13,7};

int array3[] = {-8, -6, -7, 9};

int array4[] = {21, 23, 27,15,0};

int *t[] = { array1, array2, array3, array4};

display(t);

}

void display(int *tb[])

{

printf("%d and ", *(tb[2]+1));

printf("%d", tb[3][1]);

If ‘a’ is declared as one-dimensional array in ‘C’ then

a) *(a + i) is same as *(&a[i])

b) *(a + i) is same as *a + i

c) &a[i] is same as a + i - 1

d) *(a + i) is same as a[i]

What is the output of the below given C program?

#include <stdio.h>
int main()
{
int loops = 0;
int _shift = 7916; 
while(_shift)
{
loops++;
_shift >>= 2;
}
printf("%d",loops);
}

Consider the C program given belwo

#include <stdio.h>
struct charNode
{
char a, b, c, d; 
};
int main()
{
struct charNode ch = {'o'+3,'e'+10,'j'+15,'t'+1};
struct charNode *ptr = &ch;
printf("%c, %c",*(char *)ptr + 1,*((char *)ptr + 2));
}

What is the output?

Consider the following definition of array in C:

int a [ ] [2] [3]=

      {

         {

            {1, 2, 3},

            {4, 5, 6}

         },

         {

           {10, 20, 30},

           {40, 50, 60}

        },

        {

           {100, 200, 300},

           {400, 500, 600}

   }

};

Which of the following expressions would give value 1 for the array defined above?

(a) a[0] [0] [0]

(b) * * * a

(c) * * * a[0]

(d) * * a[0] [0]

Consider the below given code.

#include<stdio.h>

int main()

{

static int x[ ] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

int i;

for(int i = 2; i < 7; i++)

x[x[i]] = x[i];

int sum = 0;

for(int j = 0; j < 10;j++)

sum = sum + x[j];

printf("%d",sum);

}

The value printed of sum is ____.
