Answer:
An error will be occurred here. In C++ a function must be like
returntype function_name(){
}
but the functions in given class does not have returntype given. So there will be a syntax error.
If the returntype is defined then the code does not show any output since nothing is printed in the main function.
Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header file.
int main() //defining main method
{
char i,j; //defining variable
for (i='a'; i<='e'; i++) //outer loop for column
{
for (j='a'; j<='e'; j++) //inner loop for row
{
printf("%c%c\n",i,j); //print value
}
}
return 0;
}
Output:
image.
Explanation:
- In the above C language program, firstly a header file is included. Then the main method is defined in this, a method contains a char variable that is "i and j". This variable is used in for loop, that is used to print the pattern.
- To print the following patter two for loop is used the outer loop is used for print columns and the inner loop prints row.
- In C language to print character, we use "%c" inside a loop print function is used, that prints characters.
I am not sure but I think that it is either the First option or the Third option but you would probably need more information.
These principles are not explicit to one kind of program and are increasingly broad "best practice" rules that assist designers with composing code that is easier to maintain.
<u>Explanation:</u>
A set of programming guidelines that are executed to play out a particular undertaking according to the prerequisites of the client is known as programming. Every product has some essential standards to follow. In light of all product frameworks have basic quality traits, including accessibility, modifiability, execution, security and wellbeing, testability and ease of use, the key programming thoughts give basic arrangements or strategies to help those characteristics.
It is generally less expensive, over the long haul, to utilize programming designing strategies and methods for programming frameworks instead of simply compose the projects as though it was an individual programming venture.
Answer:
Java Class given below
Explanation:
class ReadOnly
{
protected int val;
public ReadOnly(int arg)
{
val = arg;
}
public int getVal()
{
return val;
}
}
class ReadWrite extends ReadOnly
{
private boolean dirty;
public ReadWrite(int arg)
{
super(arg);
dirty = false;
}
public void setVal(int arg)
{
val = arg;
dirty = true;
}
public boolean isDirty()
{
return dirty;
}
}
