What is the correct way to declare a variable in C?

• int a = 5;

• a = 5;

• integer a = 5;

• declare int a;

What type of value does `int a = 5;` store by default in C?

• An unsigned integer

• A signed integer

• A decimal number

• A character

What does `int a = 4 % 2;` store?

Hint: Remember `%` is the modulus operator.

• 0

• 1

• 2

• 3

What is the binary representation of the decimal number 4?

• 1

• 10

• 11

• 100

What does `int a = 1 << 3;` return in binary?

• 1

• 100

• 1000

• 0

If 2 is 10 in binary, what will `int a = 2 >> 1;" return in binary?

• 10

• 100

• 1

• 0

Given the following code, how do you declare a variable of type Point?

struct Point {

int x;

int y;

};

• A) Point p;

• B) struct Point p;

What does `Coordinate` mean here?

typedef struct Point {

int x;

int y;

} Coordinate;

• It is the alias of `struct Point`

• It is a new type unrelated to `struct Point`

• It renames the int type to Coordinate

• It declares a global variable named Coordinate

Given the following code, how do you declare a variable of this type?

typedef struct Point {

int x;

int y;

} Coordinate;

• Point p;

• struct Point p;

• Coordinate p;

• Coordinate Point p;

Considering the following code, select which statement is true:

int a = 4, b = 5;

if(a = b){

printf("They are the same");

};

• The code assigns b to a instead of comparing them

• Nothing is wrong; the code works as intended

• The condition will always evaluate to true
