Question

Q1. Write a function prototype and a function definition called minimum that receives an

array of type double, and the number of elements in the array. It returns the maximum value in the array.

Q2: Write a function called failed which receives an integer array of scores and the number of elements.

Return the number of students who scored > 80.

Q3:

Rewrite this else- if code segment into a switch statement if (num >= 1 && num < 5)

a = a - 1;

else if (num == 7)

{

b = b + 1;

x = 6;

}

else if (num > 8 && num <= 11)

c = c + 1;

else

d = d * 3;

Q4

Rewrite the following conditional expressions as if/else statement:

num+= count == 1 ? sales : count * sales;

Q5

Rewrite the following conditional expressions as if/else statements:

cout << (((num % 2 ) == 1) ? “Odd ” : “Even ”) ;

Explanation / Answer

Question 1:

//protoType

double minimum(double array[],int SIZE);

//function

double minimum(double array[],int SIZE)
{
double min = array[0]; //assume that starting index value has min value
// loops from 1 to length of array
for(int i=1; i < SIZE ; i++)
{
if(min > array[i])
min = array[i];
}
return min;
}

Sample program to test:

#include <iostream>

using namespace std;
double minimum(double array[],int SIZE);
int main()
{
double a[] = {1,2,3,4,5,6,7,8,9};
cout << minimum(a,9) << endl;

return 0;
}

double minimum(double array[],int SIZE)
{
double min = array[0]; //assume that starting index value has min value
// loops from 1 to length of array
for(int i=1; i < SIZE ; i++)
{
if(min > array[i])
min = array[i];
}
return min;
}

Question 2:

int failed (int array[],int SIZE)
{
int count = 0; //hold the student count greater then 80
// loops from 1 to length of array
for(int i=1; i < SIZE ; i++)
{
if(array[i] > 80)
count++;
}
return count;
}

Sample program to test:

#include <iostream>

using namespace std;
int failed (int array[],int SIZE);
int main()
{
int a[] = {10,89,83,94,55,96,77,88,69};
cout << failed(a,9) << endl;

return 0;
}

int failed (int array[],int SIZE)
{
int count = 0; //hold the student count greater then 80
// loops from 1 to length of array
for(int i=1; i < SIZE ; i++)
{
if(array[i] > 80)
count++;
}
return count;
}

Question 3:

switch(num)
{
case 1:
case 2:
case 3:
case 4:
a = a - 1;
break;
case 7:
b = b + 1;
x = 6;
break;
case 9:
case 10:
case 11:
c = c + 1;
break;
default:
d = d * 3;
break
  
}

Question 4:

if(count == 1)
{
num += sales;
}
else
{
num += count * sales;
}

Question 5:

if((num % 2 ) == 1)
{
cout << "Odd ";
}
else
{
cout << "Even ";
}
