The fourth choice is correct.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
char grade(double marks){
if(marks>=90)
{
return 'A';
}
else if (marks >=80 && marks<90)
{
return 'B';
}
else if (marks >=70 && marks<80)
{
return 'C';
}
else if (marks >=60 && marks<70)
{
return 'D';
}
else if ( marks<60)
{
return 'F';
}
}
int main()
{
double marks;
cout <<"Ener marks";
cin >>marks;
char grd=grade(marks);
cout<<"Grae is "<<grd;
return 0;
}
Explanation:
Take input from user for grades in double type variable. Write function grade that takes a parameter of type double as input. Inside grade function write if statements defining ranges for the grades. Which if statement s true for given marks it returns grade value.
In main declare a variable grd and store function returned value in it.
Answer:
a. grep 'b[au]nk$' myLine
Explanation:
grep is a command used for searching a specified pattern in a given text.
Our goal is to match the character sequence - bank or bunk at the end of line in a given line referenced by myLine.
The regular expression for the specified match criterion is:
b[au]nk$
The second character can be either a or u.
$ indicates match at end of line.
So the overall grep command is :
grep 'b[au]nk$' myLine
The code for the above problem is:
<span>/* package whatever; // don't place package name! */
import java.util.*;
import java.lang.*;
import java.io.*;
/* Name of the class has to be "Main" only if the class is public. */
class Ideone{ public static void main (String[] args) throws java.lang.Exception
{
for(int i=11; i<=121; i=i+2){
System.out.print(i); System.out.print(" ");
}
}<span>}
I hope this is the answer that you were looking for. </span></span>
A should be correct i think
