Question

1. What are the values of int x in the following C++ statement? 2 each a) x = 18 % 5; b)x= (4/5)==0.8; c)X =( 4 - 3 * 2 == 2) ?0:1; 2. What will x and y be when each part starts out with integers x = 6, y = -4 and z=5? 2 each a) x *= 12 - x; x becomes b) z= x++ + x; x becomes z becomes c) z=++x+x; x becomes z becomes 3. What does the following code fragment produce? // 3 pts int x = 0, y = 1; if (!(x = y)) cout << "True": else cout << "False"; output: 4. Write the C++ code fragment needed to represent the following. N is a random integer with 3 <N<8. 4 pts

Can i get the answers for 1,2,3 and 4

Answer 1

The answer to this question is as follows:

The answer to the first question is:

1.

a) x=18%5 it gives 3 the remainder is 3 with the % modulus operator we can store the remainder value in x the output is 3

b) 1 the / operator is used to produce the quotient so the answer when 4/5 gives 0 so checking the value 0==0.8 the condition fails so it gives the output 1 it means false

c) x=(4-3*2==6)?0:1

The * operator is having high precedence and next - is having next precedence

4-6==2 then -2==2 then the condition fails then it gives the value 1

The answer to the second question is as follows:

x=6, y=-4, z=5

a)x*=12-x then this statement is written as x=x*(12-x) gives the value x=6*(12-6)=36

b)The value of z with the value of x=6 is z=13

c) The value of z with the x=6 is z=16

The answer to the third question is as follows:

The ouput is false

The answer to the fourth question is as follows:

#include <iostream>

using namespace std;

int main() {
int random_value,min=3,max=8;
   random_value = (rand() % ((max-min)+1) + min);
   cout<<random_value;
}
