That’s cool I’ll play the game tonight if I can
```
#!/usr/local/bin/python3
foo = float( input( "Enter a number: " ) )
if( foo < 0.0 ):
print( "negative" )
elif( foo > 0.0 ):
print( "positive" )
else
print( "zero" )
exit( 0 )
```
Answer:
Following are the program in the C++ Programming Language.
//set header file
#include <iostream>
//set namespace
using namespace std;
//define class
class format
{
//set access modifier
public:
//set string type variable
string res;
//define function
void names(string first_name, string last_name)
{
//set if-else if condition to check following conditions
if(first_name.length()>0 && last_name.length()>0)
{
res="Name: "+last_name+", "+first_name;
}
else if(first_name.length()>0 and last_name.length()==0)
{
res="Name: "+first_name;
}
else if(first_name.length()==0 and last_name.length()==0)
{
res="";
}
}
//define function to print result
void out(){
cout<<res<<endl;
}
};
//define main method
int main() {
//set objects of the class
format ob,ob1,ob2;
//call functions through 1st object
ob.names("John","Morris");
ob.out();
//call functions through 2nd object
ob1.names("Jhon","");
ob1.out();
//call functions through 3rd object
ob2.names("", "");
ob2.out();
}
<u>Output</u>:
Name: Morris, John
Name: Jhon
Explanation:
<u>Following are the description of the program</u>:
- Define class "format" and inside the class we define two void data type function.
- Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
- Define void data type function "out()" to print the results of the variable "res".
- Finally, we define main method to pass values and call that functions.
Answer:
#here is function in python
#function that return integer if input can be converted to int
#if not it will return a string "Cannot converted!!"
def get_integer(inp):
try:
return int(inp)
except:
return "Cannot convert!!"
print()
#call the function with different inputs
print(get_integer("5"))
print(get_integer("Boggle."))
print(get_integer(5.1))
print()
Explanation:
Define a function get_integer() with a parameter.In this function there is try and except.First try will execute and if input can be converted to integer then it will convert it into integer and return it.If it will not able to convert the input into integer then except will return a string "Cannot convert!!".In the function get_integer(), there is no use of any conditionals or type function.
Output:
5
Cannot convert!!
5
