Question

• If the result is an integer value write the integer without commas or decimals
• If the result is a double value write the decimal to exactly 2 decimal places
• If the operation is division or module and the denominator is zero, write: Invalid
• If the operation is division or modulo and the denominator is a negative value, write: Varies
• If the operation is module and the numerator is a negative value, write: Varies

#define IVAR 100
double x, y;
int a, b, i;
a = 9;
b = 4;
y = 5.0;

x = b / a;

Answer 1

double x, y;
int a, b, i;
a = 9;
b = 4;
y = 5.0;

x = b / a;

The value of x after executing this code will be 0

This is because, both b and a are integers, so b/a yields integer division by default. Even though x is a double variable, the integer division of b/a returns 0 instead of 0.44. If you want to do this correctly, you will need to cast the result of b/a into double. That is changing x=b/a; into x=(double)b/a; in that case, the value of x will be 0.4444

Let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks
