Problem:

Given the following declarations, what result is stored in each of
the listed assignment statements?
int iResult, num1 = 25, num2 = 40, num3 = 17, num4 = 5;
double fResult, val1 = 17.0, val2 = 12.78;
a. iResult = num1 / num4;
b. fResult = num1 / num4;
c. iResult = num3 / num4;
d. fResult = num3 / num4;
e. fResult = val1 / num4;
f. fResult = val1 / val2;
g. iResult = num1 / num2;
h. fResult = (double) num1 / num2;
i. fResult = num1 / (double) num2;
j. fResult = (double) (num1 / num2);
k. iResult = (int) (val1 / num4);
l. fResult = (int) (val1 / num4);
m. fResult = (int) ((double) num1 / num2);
n. iResult = num3 % num4;
o. iResult = num2 % num3;
p. iResult = num3 % num2;
q. iResult = num2 % num4;

Output:

Not Applicable

Solution:

a. iResult = num1 / num4;
iResult is assigned 5
b. fResult = num1 / num4;
fResult is assigned 5.0
c. iResult = num3 / num4;
iResult is assigned 3
d. fResult = num3 / num4;
fResult is assigned 3.0
e. fResult = val1 / num4;
fResult is assigned 3.4
f. fResult = val1 / val2;
fResult is assigned 1.3302034...
g. iResult = num1 / num2;
iResult is assigned 0
h. fResult = (double) num1 / num2;
fResult is assigned 0.625
i. fResult = num1 / (double) num2;
fResult is assigned 0.625
j. fResult = (double) (num1 / num2);
fResult is assigned 0.0
k. iResult = (int) (val1 / num4);
iResult is assigned 3
l. fResult = (int) (val1 / num4);
fResult is assigned 3.0
m. fResult = (int) ((double) num1 / num2);
fResult is assigned 0.0
n. iResult = num3 % num4;
iResult is assigned 2
o. iResult = num 2 % num3;
iResult is assigned 6
p. iResult = num3 % num2;
iResult is assigned 17
q. iResult = num2 % num4;
