Question

Evaluate the following expressions:


a. N+= N++ + ++N ;

System.out.println(N); ( if N is 12 initially)

b. int x=4,y;

y= (x++ )+( --x )+ x++;

System.out.println(y);

c. System.out.println( a*(++b )%c); if a=2,b=7,c=4

d. a+=b++ %7 + b++ + ++b - --c /5

System.out.println(a); (if a=2, b=4,c=8)​

Answer 1

Answer:

#include<stdio.h>

int main()

{

int x = 10;

float y = 10.0;

if (x == y)

printf("x and y are equal");

else

printf("x and y are not equal");

}

Explanation:

x and y are equal

Description : if (x == y) here we are comparing if (10 == 10.0) hence this condition is satisfied. Because we cannot compare int

and float so the int is converted to float and then compared. Hence it prints “x and y are equal”.
