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.

The answer is the last option
import java.util.*;
public class myClass {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
System.out.print("Input a String: ");
String str = scan.nextLine();
System.out.print("Input an integer: ");
int num = scan.nextInt();
for(int i=str.length()-1; i>=0; i--) {
for(int j=0; j<num; j++) {
System.out.print(str.charAt(i));
}
}
}
}
Answer:
public class Main {
public static void main(String[] args)
{
int n,m;
int k=5;
for(n=1;n<=k;n++)
{
for(m=1;m<=n;m++)
System.out.print(m);
System.out.print(" ");
}
}
}
Explanation:
The solution to this problem is the use of nested loops of an inner and outer loop to generate a half pyramid of numbers, but displayed on the same line so we have a sequence 1 12 123 1234 12345. The outer loop iterates for n=1 to n<=5 and the inner loop that has the print statement prints the integers from for m = 1 to m<=n.
Note that the value k = 5 is hard coded which in some sense is the number of rows, that is the length of iteration of the outer loop.
