Question

C programming

Show the result of evaluating each of the following expressions. (a) (4 * 3) == (3 * 4) (b) 4 * (3 == 3) * 4 (e) (('h' + 'i') && '\0') (f) (13 < 7 || 7 > = 13) || (13 < 7 && 7 > = 13) || (7 < 13 && 13 > = 7) (g) (13 < 7 || 7 > = 13) && (13 < 7 && 7 > = 13) && (7 < 13 && 13 > = 7) For each of the following, determine how many times the function event() will be called, and the final value of the loop variable i. a) for (i = 4: i > = 0: --i) { event(): } # of times: ___________ final value of i: __________ b) i = 0: while (--i) { event (): --i: } # of times: _______ final value of i: ________ c) for (i = 0: i < 5: i += 2) for (j = 0: j < 5: j +=3) event(): # of times: ________ final value of i: _______

Answer 1

2.a) here i = 4 the loop executes until i values becomes 0 so the loop iterates 5 times abd the value of i is 0

b) here

Initially i value is 0 so after loop iteration until normal console. Limit reached

So loop iterates infinite times and the value of i also infinity

So in my console the last value of i is - 2422

C) in this double loop the loop iterates 6 times and the value of i is 4

1)here the given expression is 4*3==3*4

So 12==12 which is true

B) here 4*(3==3)*4 which is also true because the association also the value Is true

e) first (h+i) value is evaluated and this value can be evaluated with && condition with null operator

F) (13<7||7>=13)

False or false is false

(13<7&&7>=13)

False and false is true

(7<13&&13>=7)

True and false is true

From statements 1 and 2 is false or true will evaluates true

Now from true or true will lead to TRUE

G)

13<7||7>=13)

False or false is false

(13<7&&7>=13)

False and false is true

(7<13&&13>=7)

True and false is true

From statements 1 and 2 is false and true will evaluates true

Now from true and true will lead to FALSE
