Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of
Answer:
A type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another.
Once a virus has successfully attached to a program, file, or document, the virus will lie dormant until circumstances cause the computer or device to execute its code. In order for a virus to infect your computer, you have to run the infected program, which in turn causes the virus code to be executed.
The answer is the letter (D)
Answer:
Following are the solution to the given choices:
Explanation:
Given:
double currentBalance[91];//defining a double array
In point a:
The name of the array is= currentBalance.
In point b:
91 double values could be saved in the array. It requires 8bytes to hold a double that if the array size is 91*8 = 728
In point c:
Each element's data type is double.
In point d:
The array index range of values is between 0 and 90 (every array index starts from 0 and ends in N-1, here N=91).
In point e:
To access first element use currentBalance[0], for middle currentBalance[91/2] , for last currentBalance[90]
Answer:
The function code and the formula for the above question is listed below:
Explanation:
Function:
float typing_speed(int Number_of_words, int Time_in_seconds)
{
float time= Time_in_seconds/60;
float speed= Number_of_words/time;
return speed;
}
Formula for this algorithm or program:
Number of words per minute= number of words/ Time(in minutes).
Function Explanation
- The above function defined in the c-language code, which is used to return the typing speed for any user when he enters the number of words and the time in seconds.
- The speed is calculated with the help of the above-defined formula.
- The first statement of the code is used to change the time in a minute.
- The second statement of the code is used to calculate the speed by the help of speed formula.
- Then the third statement returns the value of the speed variable.
