Predict the output

Predict the output of the following coding questions of C language:

1. Find the output of the following code?

void main()

{

int a[2][3] = {1, 2, 3, 4, 5};

int i = 0, j = 0;

for (i = 0; i < 2; i++)

for (j = 0; j < 3; j++)

printf("%d\t", a[i][j]);

}

2. Find the output of the following code?

void main()

{

int a[2][2] = {{2,3},{1,6}};

printf("%d", &a[0][1] - &a[0][0]);

}

3. What is the size of the array arr if it is declared as, float arr[3][2][2]?

4. Find the output of the following code?

void main()

{

char data[2][3][2]={0,1,2,3,4,5,6,7,8,9,10,11};

printf("%o",data[0][2][1]);

}

5. Find the output of the following code?

void main()

{

short num[3][2]={3,6,9,12,15,18};

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

}

6. Find the output of the following code?

void main()

{

char *ptr="c programming";

printf("%c",3[ptr]);

}

7. Find the output of the following code?

void main()

{

int array[2][3]={5,10,15,20,25,30};

int (*ptr)[2][3]=&array;

printf("%d\t",***ptr);

printf("%d\t",***(ptr+1));

printf("%d\t",**(*ptr+1));

printf("%d\t",*(*(*ptr+1)+2));

}

8. Find the output of the following code?

void main()

{

int arr[][3]={{1,2},{3,4,5},{5}};

printf("%d %d %d",sizeof(arr),arr[0][2],arr[1][2]);

}

9. Find the output of the following code?

void main()

{

char arr[20]="Mahendra Singh Dhoni";

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

}

10. Find the output of the following code?

void main()

{

int a[5] = {5, 1, 15, 20, 25};

int i, j, m; i = ++a[1]; j = a[1]++;

m = a[i++]; printf("%d, %d, %d", i, j, m);

}

11. What is the output of the following program?

int a[6] = {2, 7, 3, 1, 5, 9};

printf(“%d”,a[5] + 6);

12. What will be the output of the following code ?

void main()

{

int a[5]={3,5,6,2,7};

int i=3;

if(a[i]==a[i+3])

printf("true");

else

printf("false");

}

13. What will be the output of the following code ?

void main()

{

int a[5] = {5,7,3,1,2};

a[2]=a[1];

a[1]=a[3];

a[2]=a[2]+a[3];

printf("%d\t%d", a[1],a[2]);

}

14. Write the output of the following code?

void main()

{

int a[3][2] = {10. 20, 30, 40, 50, 60};

printf(“%d”, a[0][4]);

}

15. Write the output of the following code?

void main()

{

int x[10] = {5};
