Question

Please complete the following two short functions utilizing C++ format:

1. Write the definition of a function absoluteValue , which receives an integer parameter and returns the absolute value of the parameter's value.

So if the parameter's value is 7 or 803 or 141 the function returns 7, 803 or 141 respectively. But if the parameter's value is -22 or -57, the function returns 22 or 57 (same magnitude but a positive instead of a negative). And if the parameter's value is 0, the function returns 0.

2. Write the definition of a function signOf , which receives an integer parameter and returns a -1 if the parameter is negative, returns 0 if the parameter is 0 and returns 1 if the parameter is positive.

So if the parameter's value is 7 or 803 or 141 the function returns 1. But if the parameter's value is -22 or -57, the function returns -1. And if the parameter's value is 0, the function returns 0.

Explanation / Answer

int absoluteValue(int k)

{

if(k<0) return -1*k;

return k;

}

int signOf(int a)

{

if(a==0) return 0;

if(a>0) return 1;

return -1;

}
