Question

Assume i = 4, j = 9, k = 5 and m = -3. What does each of the following statements print?

a) printf("%d", i == 4);

b) printf("%d", j!= 3);

c) printf("%d", i >= 5 && j < 2);

d) printf("%d", !m || k > m);

e) printf("%d", !k && m);

f) printf("%d", k - m < j || 5 - j >= k);

g) printf("%d", j + m <= i && !0);

h) printf("%d", !(j + m)); i) printf("%d", !(k < m)); j) printf("%d", !(j < k));

Answer 1

i = 4, j = 9, k = 5 and m = -3.

printf("%d", i == 4);

Yes. i==4

Ans:1

printf("%d", j!= 3);

i is not equal to 3. True

Ans:1

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", i >= 5 && j < 2);

i>=5 ==>False

j<2==>False

0 && 0 =0

ANs:0

printf("%d", !m || k > m);

m is a non zero number. Hence !m is 0.

k>m is true.

0||1=1

Ans:1

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", !k && m);

k is a non zero number .!k is 0

m is also a non zero number

Hence k&&m is 0 && 1==>0

ANs: 0

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", k - m < j || 5 - j >= k);

k-m=5+3=8 ; 8<j (true)

5-j=5-9=4;4>=k (true)

true|| true==>true(1)

Ans:1

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", j + m <= i && !0);

j+m=9-3=6; 6<=i (No- False)

!0==>true

true && false==>false(0)

Ans:0

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", !(j + m));

j+m=9-3=6

Its non zero number. Hence !1= 0

Ans:0

++++++++++++++++++++++++++++++++++++++++++++++++++++++++
printf("%d", !(k < m));

k<m is false.

!(false)==> True

Ans:1

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

printf("%d", !(j < k));

j<k is false;

!(fasle)==>true

Ans:1
