y/n function
My y/n function is not working. If you run it you would understand how it looks.

This is just plain all wrong. In many ways.
Here it is, less wrong:
1 2 3 4 5 6 7 8 9
|
if (selection == 'y' || selection == 'Y')
{
main();
}
if (selection == 'n' || selection == 'N')
{
exit(0);
}
|
but this is still wrong.
You must NEVER EVER call
main()
. It's forbidden in C++. You are not allowed to call
main()
.
You should not be calling
exit()
. You should be ending this program by
return
from
main()
.

if (selection == 'y')
if (selection == 'Y')
try
if (selection == 'Y' || selection == 'y')
|
and simillar for N and n.
1 2 3 4 5 6 7 8 9 10 11

int main()
{
while ( true )
{
int a, b, c;
// etc.
// etc.
cin>>selection;
if (selection == 'n' || selection == 'N' ) break;
}
}
