Thread: Help Me!!!!!!!!!

ok im new 2 c++ and im trying to make a basic program that stats
push q to square s subtract a 2 add d 2 divide
so what do i do after i type this
if its a lot of lines to do this if u wouldnt mind writing it or just say its too many lines
(if your too lazy ad dont wat to help me) >:|
--------------------------------------------------------------------------
#include < iostream.h>
int main ()
{
int x,q,s,a,d;
cout << "x=square d=divide a=add s=subtract q=square";
----------------------------------------------------------------------------
now what do i say
cin >> x;
cin >> d;
....... and so on
---------------------------------------------------------------------------
or do i skip that and say
if (x)
bla bla
if (q)
bla bla
........... and so on
----------------------------------------------------------------------------

Or am i just totally off track

i would really like it if u helped me out.......

thx

I will not post it all, but I will post what you want:

int main()
{
char choice;

cout << "x=square d=divide a=add s=subtract";
cin >> choice;

if((choice == 'x') || (choice == 'X'))
{
// Square
}
if((choice == 'd') || (choice == 'D'))
{
// Divide
}
if((choice == 'a') || (choice == 'A'))
{
// Add
}
if((choice == 's') || (choice == 'S'))
{
// Subtract
}

return 0;
}

This checks to see if they do uppercase OR lowercase

if((choice == 'x') || (choice == 'X'))
{
// Square
}
if((choice == 'd') || (choice == 'D'))
{
// Divide
}
if((choice == 'a') || (choice == 'A'))
{
// Add
}
if((choice == 's') || (choice == 'S'))
{
// Subtract
}

This is bad style. The evaluation process continues even if the first one was true...also, instead of comparing both lower and uppercase, just convert the input into one or the other ( or else make a copy of it first to preserve the input)...

And Prodigy: I think you are confusing variables with the input expected...there is no need for more than one here.

Code:

#include < iostream.h>
 
int main () 
{ 

char c;

cout << "x=square d=divide a=add s=subtract q=square"; 

cin >> c;


c = tolower(c);


if( c == 'x' ) 
 { 
  // Square 
 }
else 
if( c == 'd' ) 
 { 
  //...divide... 
 } 
else 
if( c == 'a' ) 
 {
   //...do addition...
 } 
else 
if( c == 's' )
 {
   //...do subtraction...
 } 
else 
if( c == 'q' )
 {
   //...do square...
 } 
 


return 0;
}

...also you could use a switch statement instead...
