Write a program that uses nested loop or for statements to display Pattern A below, followed by an empty line and then another s
JulsSmile [24]

Answer:

public class Pyramid {

   public static void main(String[] args) {

             int h = 7;

       System.out.println("Pattern A");

               for(int i = 1; i <= h; ++i)

               {

                   for(int j = 1; j <= i; ++j) {

                       System.out.print("+");

                   }

                   System.out.println();

               }

       System.out.println();

       System.out.println("Pattern B");

               for (int i = 1; i<=h; ++i)

               {

                 for(int j = h; j >=i; --j){

                     System.out.print("+");

                 }

                   System.out.println();

               }

           }

       }

Explanation:

  • The trick in this code is using a nested for loop
  • The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
  • The inner for loop which prints the (+) sign runs from j = 0 to j<=i
  • It prints the + using the print() function and not println()
  • In the pattern B the loop is reversed to start from  i = height

QveST [7]

Answer:

#include <iostream>

#include <vector>

using namespace std;

void calGPA();

vector<int> g;

vector<int> h;

int main(){

   char pushMore = 'y';

   int fg, fh;

   for (;;){

       if (pushMore == 'n'){

           break;

       } else{

           cout<< "Enter integer for grade: ";

           cin>> fg;

           cout<< "Enter integer for credit hours: ";

           cin>> fh;

           g.push_back(fg);

           h.push_back(fh);

           cout<< "Do you want to add more grade and credit hours? y/n: ";

           cin>> pushMore;

       }

   }

   calGPA();

}

void calGPA(){

   double total = 0, GPA;

   for (int i = 0; i < g.size(); ++i) {

        total +=  g.at(i) * h.at(i) ;

   }

   cout<< "The GPA is : "<< total/g.size();

}

Explanation:

The C++ source code above defines two vectors 'g' and 'h'. The latter holds the grades of a student while the former holds the credit hours for the subject taken. The void 'calGPA' function calculates and prints the student's GPA.
