trouble with if else statements

I"m trying to make my program decide when an input is invalid and use the right cout statement here is the code


if( s_code = 1022)
cout <<endl;
else
cout << "DENIED: Security Code Mismatch" << endl;

if( zip_code = 92831)
cout <<endl;
else
cout << "DENIED: Zip Code Mismatch" <<endl;
if(exp_month <= 12 && exp_year <= 2009 )
cout << endl;
else
cout << "DENIED: Card has Expired" << endl;
if( avail_b >= 12000)
cout << " APPROVED"<<endl<<endl<<"Saving new data..."<<endl;
else
cout << "DENIED: Insufficient Funds" <<endl;


// any input the program prints out " APPROVED" i want it to only choose approved if all the statemetn are true

If I show you

Code:

---

s_code = 1022;

---

what does that code do?

Now, why do you think it does something different just because it's in an if statement?

What i am understanding what you want is the below code snippet

Code:

---

if (s_code = 1022)
  cout <<endl;
 else
  cout << "DENIED: Security Code Mismatch" << endl;

if ((zip_code = 92831)                    &&
    (exp_month <= 12 && exp_year <= 2009) &&
    (avail_b >= 12000))
  cout << " APPROVED"<<endl<<endl<<"Saving new data..."<<endl;
 else
  cout << "DENIED: Insufficient Funds" <<endl;

---

I didn't understand what you fully but i tried :)

that way, you assigned the valu of variable


if(s_code=1200)
is the same as

s_code=1200; if(s_code !=0)cout<<endl;

if ouy ned the test is

if(s_code==1200)...

Ok so I figured out how to write the if else statements correct....

if( s_code==1022)
cout << "DENIED: Security Code Mismatch" << endl;
else if( zip_code == zip)
cout << "DENIED: Zip Code Mismatch" <<endl;
else if(exp_month <= 12 && exp_year <= 2009 )
cout << "DENIED: Card has Expired" << endl;
else if( avail_b >= amount)
cout << "DENIED: Insufficient Funds" <<endl;
else
cout <<" APPROVED"<<endl<<endl<<"Saving new data..."<<endl;

// now when I enter in an s_code value that is "1022" the program still says "DENIED...." I dont know why eventhoguht i set it to exactly 1022?

any ideas?

I"m fairly new to programming so please bare with me

Because you print DENIED exactly when s_code is 1022.

so i want it to only say the "denied" statement when it's false, meaning anything else than 1022

So write it. This is not difficult.

You need to look up the 'not equals to' operator.
