Answer:
int* calculate(int a,int b,int c){
int result[] = {0,0};
int sum = a+b+c;
int product = a*b*c;
result[0] = sum;
result[1] = product;
return result;
}
Explanation:
The function is a block of the statement which performs the special task.
The function can return one integer, not more than one integer.
If we want to return multiple values then, we can use array.
we store the result in the array and return that array to the main function.
This is the only possible way to return multiple values.
So, define the function with return type array and declare the array with zero value.
Then, calculate the values and store in the variable after that, assign to the array.
Finally, return that array.

Answer:
The problem that created due to the difference in the model of programming language and the database model.
Explanation:
The practical relational model has three components which are as follows
1. Attributes
2. Datatypes
3. Tuples
To minimize this problem
1. We switch low pass L-Network to high pass L-network
2. We switch high pass L-Network to low pass L-network
3. We use the impedence matching transformer
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
