Identify the compilation errors in the given C program

• & operator is missing in scanf()

• Semicolon is used for the case label M, instead of colon

• No single quote is used for the case label T

• break statement is missing in second case block

Guess the output correctly

• A 65 65 A

• A 65 65 65

• A 65 A 65

• Error

#include <stdio.h>

int main()

{

int x[ ][4] = {10, 20, 30, 40, 50, 60};

printf("%d \n %d", x[1][1], x[1][2]);

}

• First it prints 60, then prints either 0 or Garbage value

• Error, as array initialization is wrong

• Prints 60 only

• First it prints 40, then prints either 0 or Garbage value

Assume the size of int is 4 bytes. if the base address of array is 4210, then the address of 7th element is __________

• 4234

• 4238

• 4230

• 4217

Identify the correct 1D, 2D array initialization

• int a[ ] = {10, 20};

• int a[ ][ ] = {10, 20};

• int a[ ][2] = {10, 20};

• int a[10] = {10, 20};

float array is initialized as follows: float x[ ] = {3.2, 2.3, 4.3, 3.4, 4}. Identify the option when the statement printf("%f",x[4]); is executed.

• 4.000000

• 4

• Error, as float array cannot have int item

• 4.0

Identify the Output when the given C code, containing the Bitwise Operation, is executed:

int main()

{

int a = 5;

int b = 6;

printf("%d %d", a & b, a | b);

}

• 4 7

• 7 4

• 0 1

• Operations are Not possible

Identify the Output when the given C code, containing the Logical Operation, is executed:

int main()

{

int a = 5;

int b = 6;

int c = 0;

printf("%d %d %d %d", a && b, a || b, a && c, c || a);

}

• 1 1 0 1

• 4 7 0 5

• 1 1 0 0

• Operations are Not possible

Identify the output, when the C code, containing relational and logical operations, is executed.

int main()

{

int a = 5;

int b = 6;

int c = 0;

printf("%d %d %d %d", a < b, a > b, a < b && a > c, c < a);

}

• 1 0 1 1

• 1 1 1 1

• 0 1 0 1

• 0 0 1 1

Identify the compilation errors in the given code

int main()

{

int n=5, i;

do

{

s = s+i;

i++;

} while(i<n)

printf("Sum is %d", s);

}

• Semicolon is missing in while statement

• s is not declared

• i is not initialized

• do while should be used together, not as given in the question
