Question

READ and FOLLOW all directions

(post a screenshot of the code if possible and proof that the program can run)

C++ code language, using FOR and WHILE loops, and ARRAY to solve

CLEAN CODE IS A MUST! WRITE FOR READABILITY

1. Write a program that converts decimal number to hexadecimal

1a) Write a program using nested loops that asks the user to enter a value for the number of rows to display. It should display that many rows as asteriks with 1 asterik in the first row, 2 in the second row, and so on. However the last asterik in each row should be aligned (PRECEDED BY SPACES) (DO NOT USE SET PRECISION)

Answer 1

1. Program that converts decimal number to hexadecimal

Code in c++:

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

long int decnum, rem, quot;

char hexdecnum[100];

int i=1, j, temp;

cout<<"Enter any decimal number : ";

cin>>decnum;

quot=decnum;

while(quot!=0)

{

temp=quot%16;

if(temp<10)

{

temp=temp+48;

}

else

{

temp=temp+55;

}

hexdecnum[i++]=temp;

quot=quot/16;

}

cout<<"Equivalent hexadecimal value of "<<decnum<<" is : \n";

for(j=i-1; j>0; j--)

{

cout<<hexdecnum[j];

}

getch();

}

1a)

#include <iostream>

using namespace std;

int main()

{

int rows = 0;

int less = 1;

cout << "Enter number of rows: ";

cin >> rows;

for(int i=0; i < rows; i++)

{

for(int d=0; d < (rows - less); d++)

cout << ".";

for(int a=0; a < less; a++)

cout << "*";

cout << endl;

less++;

}

return 0;

}
