Homework SourseIm supposed to create a program that creates a calculations
Im supposed to create a program that creates a calculations table with addition, subtraction, multiplication, or division. It should ask the user what table they want and the dimensions of the table. I have code that is able to ask the user for these things and I can create successfully create the dimensions of the table but I can\'t seem to get the calculations in the middle of the table. Can someone help me understand how to get the code for the addition part of the code please? Thanks!
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
char choice;
cout << \"Welcome to the math study guide.\" << endl;
cout << \"Which arithemetic table would you like to see?\" << endl;
cout << \"1) Addition\" << endl;
cout << \"2) Subtraction\" << endl;
cout << \"3) Multiplication\" << endl;
cout << \"4) Division\" << endl;
cout << \"X) Exit the program\" << endl;
cin >> choice;
int X,Y,i,j;
cout << \"Enter the dimensions of the table.\ \";
cout << \"Enter X: \";
cin >> X;
cout << \"Enter Y: \";
cin >> Y;
if (X==0 || Y==0)
cout << \"Invalid dimensions\" << endl;
switch (choice)
{
case \'1\': cout << \"You chose Addition.\ \";
for (i=0;i<=X;i++)
cout << i << \" \";
cout<< endl;
for(j=1;j<=Y;j++)
cout << j << endl;
This outputs something like ( for a 5x5 table)
0 1 2 3 4 5
1
2
3
4
5
Solution
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
char choice;
cout << \"Welcome to the math study guide.\ Which arithemetic table would you like to see?\ 1) Addition\ 2) Subtraction\ 3) Multiplication\ 4) Division\ 0) Exit the program\" << endl;
cin >> choice;
int X,Y,i,j;
// taking user input
cout << \"Enter the dimensions of the table.\ Enter X: \";
cin >> X;
cout << \" Enter Y: \";
cin >> Y;
if (X==0 || Y==0)
cout << \"Invalid dimensions\" << endl;
else
switch (choice)
{
case \'1\':
cout << \"You chose Addition.\ \";
// nested loop to print the sum
for (i=0;i<=X;i++)
{
for(j=0;j<=Y;j++)
printf(\"%5d\",i+j); // prints sum of ith number and jth number
cout << endl;
}
break;
case \'2\':
cout << \"You chose Subtraction.\ \";
// subtraction part
break;
case \'3\':
cout << \"You chose Multiplication.\ \";
for (i=1;i<=X;i++)
{
for(j=1;j<=Y;j++)
printf(\"%5d\",i*j);
cout << endl;
}
break;
case \'4\':
cout << \"You chose Division.\ \";
// Division part
case \'0\':
cout << \"You chose to exit from the program\";
}
}

You have to use nested loop as mentioned above to get this done

4) Division
0) Exit the program
1
Enter the dimensions of the table.
Enter X: 5
Enter Y: 5
You chose Addition.
0 1 2 3 4 5
