Answer:
computer is an electronic machine which work on the basic principle" ipo"(input process and output.
it's characteristics are
Accuracy
Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.
Diligence
A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.
Versatility
Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.
Reliability
A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.
B. hand gestures
these are not verbal.
As we change password when
1. we forgot the previous password.
2. when the previous password is leaked due to some reasons.
In case 1 we can change the password to the same as well with no change the problem will be solved but for case 2 at least one or for more safety all characters should be changed.
Answer:
The program to this question can be described as follows:
Program:
#include <iostream> //defining header file
using namespace std;
int main() //defining main method
{
int x; //defining integer variable
for(x=0;x<=100;x++) //defining loop to count value from 0 to 100
{
if(x%7==0) //check value is divisable by 7
{
cout<<x<<endl; //print value
}
}
return 0;
}
Output:
please find the attachment.
Explanation:
In the above code, an integer variable x is declared, which is used in the for loop, in this loop variable "x" starts from 0 and ends when the value of x is less than and equal to 100.
- Inside the loop an, if block is used that defines a condition that is (i%7==0), it will check, that the value is divided by 7.
- In this loop, a print method is used, that prints its values.
