Explanation:
Answer:
The Correct Software
Explanation:
Some mail application have built in support to view the attachment like in a phone. While others don't, so if that is the case your device will attempt to open the file according to its extension (.exe, .txt, .js etc.) If your device doesn't have the correct software to open it, then the other things don't matter.
Answer:
The solution code is written in Python:
- def square(num):
- if type(num).__name__ == 'int':
- sq_num = num * num
- return sq_num
- else:
- return "Invalid input"
-
- print(square(5))
- print(square("Test"))
Explanation:
To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).
Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).
We can test our function by passing value of 5 and "Test" string. We will get program output:
25
Invalid input
off the top of my head I think this might be (CSMA/CD)
Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
int recurs(int x, int n)//defining a method recurs that accepts two parameter
{
if(n==0)//defining if block that checks n value
{
return 1;//return value 1
}
else//defining else block
{
return x*recurs(x,n-1);//use return keyword that retun value
}
}
int main()//defining main method
{
cout<<recurs(5,3); //use print method to call recurs method
return 0;
}
Output:
125
Explanation:
In the above-given program, the integer method "recurs" is declared which accepts, two integer variables, which are "x, n", inside the method the if conditional statement is used.
- In the if block, it checks the value of n is equal to "0" if this condition is true, it will return a value, that is 1.
- Otherwise, it will go to the else block, in this block, it will use the recursive method to print its value.
