Answer and Explanation
In C programming, switch statements allows a variable to be tested for equality against a list of values. The switch statements works by evaluating the expression and then executing all statements that follow the matching case label.
switch()status
{
case 200:
cout<<"OK(fulfilled)",
break;
case 403:
cout<<"forbidden";
break;
case 404:
cout<<not found";
break;
case 500:
cout<<"server error";
break;
}
Answer:
1.....There is a standard structure for emails. Email contents are primarily classified as two, the header and the body. We are going to see the contents come under the two subparts. The email header gives us common details about the message such as the unique identity of the message.
Explanation:
2......a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.
its components are ....
A search engine normally consists of four components e.g. search interface, crawler (also known as a spider or bot),indexer, and database.

Answer:
for(i = 0 ; i < NUM_VALS; ++i)
{
cout << courseGrades[i] << " ";
}
cout << endl;
for(i = NUM_VALS-1 ; i >=0 ; --i)
{
cout << courseGrades[i] << " ";
}
cout << endl;
Explanation:
The first loop initializes i with 0, because we have to print the elements in order in which the appear in the array. We print each element, adding a space (" ") character at its end. After the loop ends, we add a new line using endl.
The second loop will print the values in a reverse order, so we initialize it from NUM_VALS-1, (since NUM_VALS = 4, and array indices are 0,1,2,3). We execute the loop till i >= 0, and we print the space character and new line in a similar way we executed in loop1.
Answer and Explanation:
Using Javascript:
function mean(nums){
var array_numbers= new array(nums);
var meanofNums= array_numbers.reduce()/array_numbers.length;
Console.log(meanofNums);
}
Function Std(nums){
var OurArray= new Array(nums);
var meanOfnums= mean(nums);
var i;
for(i=0; i<=OurArray.length; i++){
OurArray[i]= OurArray[i]-meanOfnums*OurArray[i]-meanOfnums;
}
var al_stdOfnums= OurArray.reduce()/OurArray.length;
var stdOfnums= Math. sqrt(al_stdOfnums);
Console.log(stdOfnums);
}
function meanStdDev (nums){
mean(nums);
Std(nums);
}
/*From the code above, we have defined functions and used them in the last function definition meanStdDev (nums), making for code reusability. In defining the functions, we have followed the formulas for calculating mean and standard deviations and implemented in that order. Notice how we used a for loop in std(nums) function definition to iterate through the elements of the array nums, squaring each value and reassigning a new value for each element(using index value) in the array. We then added these values in array using reduce method, dividing by array length and square rooting the value using the math object method sqrt().*/
Answer:C
Explanation: This has no basis while the others have studied behind them.
