Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int r=26,x,y;//defining integer variable
char c;//defining a character variable
for(x= 1; y<= r; x++)//using for loop for count value
{
for(y= 1; y<= x; y++)//using for loop to convert value in triangle
{
c=(char)(y+64);//convert value into character
cout << c;//print character value
}
cout << "\n";//use print method for line break
}
return 0;
}
Output:

Explanation:
In this code, three integer variable "x,y, and r", and one character variable "c" is declared, that is used in the nested for loop, in the first for loop it counts the character value and in the next for loop, it converts the value into a triangle and uses the char variable to print its character value.
Answer:
(b) (int)(Math.random() * 101)
Explanation:
Given
--- minimum
--- maximum
Required
Java expression to generate random integer between the above interval
The syntax to do this is:
(int)(Math.random((max - min) + 1) + min)
Substitute the values of max and min
(int)(Math.random((100 - 0) + 1) + 0)
Simplify the expression
(int)(Math.random(100 + 1) + 0)
(int)(Math.random(101) + 0)
(int)(Math.random(101))
Hence, the right option is:
(b) (int)(Math.random() * 101)
