Arrays

int j[4] the sizeof(j) and sizeof(int )

will display the value

• 8,2

• 2,8

• 2,2

Which is the correct statement to declare an

array?

• int x[];

• int x[5];

• int x{5};

Find the output

void main()

{

int i,marks[5]={55,56,67,78,64};

clrscr();

for(i=2;i<=4;i++)

printf(“\n %d”,marks[i]);

getche();

}

Find the output

void main()

{

char name []={’a’,’m’,’i’,’t’};

int i;

clrscr();

for(i=0;i<=4;i++)

printf(“%c”,name[i]);

getche();

}

Choose a correct statement about C language arrays.

• An array address is the address of first element of array itself.

• An array size must be declared if not initialized immediately.

• Array size is the sum of sizes of all elements of the array.

• All the above

find the output

void main()

{

int a1[5]={1};

int b=0,k=0;

clrscr();

for(b=0;b<=4;b++)

{

printf(“%3d”,++a1[0]);

}

}

What is the output of C program.?

int main()

{

float marks[3] = {90.5, 92.5, 96.5};

int a=0;

while(a<3)

{ printf("%.2f,", marks[a]); a++; } }

• 90.5 92.5 96.5

• 90.50 92.50 96.50

• 0.00 0.00 0.00

What is the output of C program with arrays and pointers.?

int main()

{

int a[3] = {20,30,40};

int p[3];

p=&a;

printf("%d", p[0]);

}

• 20

• address of element 20

• Compiler error

What is the output of C program with arrays and pointers.?

int main()

{

int a[3] = {20,30,40};

printf("%d", *(a+1));

}

A character array always ends with

• null (‘\0’) character

• question Mark (?)

• full Stop (.)
