Answer:
Polymorphism means that a variable of supertype can refer to a subtype object.
Explanation:
For example, in Python programming language, a function that accepts an iterable object uses the concept of polymorphism because that function can accept strings, lists, tuples as arguments.
Answer:
4 5 6
Explanation:
Since there is a do-while loop, you need to check the values for each iteration until the condition (Count <= X) is not satisfied.
First iteration -> Count = 1 and X = 3, Y = 1 + 3, Write Y -> 4
Second iteration -> Count = 2 and X = 3, Y = 2 + 3, Write Y -> 5
Third iteration -> Count = 3 and X = 3, Y = 3 + 3, Write Y -> 6
After the third iteration count is equal to 4 and X is equal to 3. That is why loop ends.
Answer:
#include <iostream>
using namespace std;
int main()
{
char str[100][20];
int n;
cout<<"Strings you want to enter"<<endl;
cin>>n;
cout<<"enter n strings"<<endl;
for(int i=0;i<n;i++)
cin>>str[i];
for(int i=0;i<n;i++)
{
if((int)str[i][0]==98) //ascii value b is 98
cout<<str[i]<<endl;
}
return 0;
}
Explanation:
The above written code is for printing the strings which starts with the letter b.
To check if the string starts with a letter b we are checking the ascii value 98 which corresponds to b and then printing those strings.
Answer: In java the symbol "+" operator is used to perform string concatenation.
Explanation:
String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.
An example of String concatenation is as follows:
int age = 10;
System.out.println("The boys age is " + age);
Output:
The boys age is 10.
here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.
