Hello it is my first time here and I just started C++ so hopefully my question isn't too dumb or anything:

I was writing this thing that can do geometric series and arithmetic series. I can write the geometric series code alright and the arithmetic series code alright but once I put them together into one package where I can allow the user to choose which type or series they want the program to solve, errors started to occur. Below is my code for the combined package

```
// geometric and aritmetric series calculator
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
char operation;
cout << "press 1 for geometric series and 2 for aritmetric series" << endl;
cin >> operation;
switch(operation)
{
case '1':
double total1=0, t, u1, k, r;
cout << "This program finds the sum of any arithmetric series" << endl;
cout << "Please insert the value of the frist term:" << endl;
cin >> u1;
cout << "Please insert the value of the ratio" << endl;
cin >> r;
cout << "Please insert the amount of terms you wish to sum" << endl;
cin >> t;
cout << "Below is the results of the series, each row is the sum of one extra term" << endl;
cout << "The last result is the sum of this series with the specified amount of terms" << endl;
if (r == 1)
{
cout << "Sorry, this cannot compute the case of the ratio equals to 1" << endl;
}
while (k !=t)
{
for (double k=1; k<=t; k++)
{
total1 = ((u1*(1-pow(r,k)))/(1-r));
cout << total1 << endl;
usleep(100000);
if (k == t)
{
cout << "End of series, your final result is shown as the last number displayed" << endl;
return 0;
}
}
}
break;
case '2':
double total=0, x, a1, n, d;
cout << "This program finds the sum of any arithmetric series" << endl;
cout << "Please insert the value of the frist term:" << endl;
cin >> a1;
cout << "Please insert the value of the difference" << endl;
cin >> d;
cout << "Please insert the amount of terms you wish to sum" << endl;
cin >> x;
cout << "Below is the results of the series, each row is the sum of one extra term" << endl;
cout << "The last result is the sum of this series with the specified amount of terms" << endl;
while (n !=x)
{
for (double n=1; n<=x; n++)
{
total = ((n/2)*(2*a1+(n-1)*d));
cout << total << endl;
usleep(100000);
if (n == x)
{
cout << "End of series, your final result is shown as the last number displayed" << endl;
return 0;
}
}
}
break;
default:
cout << "Invalid input, please try again" << endl;
return -1;
}
return 0;
}
```

It gave me compiling errors that said:

~/Desktop/C++/session_2$ g++ geoariplus.cc -o geoariplus

geoariplus.cc: In function ‘int main()’:

geoariplus.cc:53: error: jump to case label

geoariplus.cc:19: error: crosses initialization of ‘double total1’

geoariplus.cc:83: error: jump to case label

geoariplus.cc:54: error: crosses initialization of ‘double total’

geoariplus.cc:19: error: crosses initialization of ‘double total1’

Below is my code for only the geometric which worked fine by itself:

```
// print geoplus
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
double total=0, x, a1, n, d;
cout << "This program finds the sum of any arithmetric series" << endl;
cout << "Please insert the value of the frist term:" << endl;
cin >> a1;
cout << "Please insert the value of the ratio" << endl;
cin >> d;
cout << "Please insert the amount of terms you wish to sum" << endl;
cin >> x;
cout << "Below is the results of the series, each row is the sum of one extra term" << endl;
cout << "The last result is the sum of this series with the specified amount of terms" << endl;
if (d == 1)
{
cout << "Sorry, this cannot compute the case of the ratio equals to 1" << endl;
}
while (n !=x)
{
for (double n=1; n<=x; n++)
{
total = ((a1*(1-pow(d,n)))/(1-d));
cout << total << endl;
usleep(100000);
if (n == x)
{
cout << "End of series, your final result is shown as the last number displayed" << endl;
return 0;
}
}
}
}
```

Below is my code to only the arithmetric series which also works fine by itself:

```
// print arithmetric adv
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
double total=0, x, a1, n, d;
cout << "This program finds the sum of any arithmetric series" << endl;
cout << "Please insert the value of the frist term:" << endl;
cin >> a1;
cout << "Please insert the value of the difference" << endl;
cin >> d;
cout << "Please insert the amount of terms you wish to sum" << endl;
cin >> x;
cout << "Below is the results of the series, each row is the sum of one extra term" << endl;
cout << "The last result is the sum of this series with the specified amount of terms" << endl;
while (n !=x)
{
for (double n=1; n<=x; n++)
{
total = ((n/2)*(2*a1+(n-1)*d));
cout << total << endl;
usleep(100000);
if (n == x)
{
cout << "End of series, your final result is shown as the last number displayed" << endl;
return 0;
}
}
}
}
```

So if you guys can help me spot what I did wrong when combining them, that would be great.

P.S. - I know I pasted quite a lot of code, hope this doesn't annoy the community here.
