Multiple conditioned if statements

I can't seem to get this to run without errors.

if (sex == "m") && ((age >= 18) && (age <= 35)) && (military = "yes") || (pushups >= 50))
			cout << "Yes, " << name << ", you may apply." << endl;


This is my final trial and I get an error with the ||'s

if (((sex == "m") && ((age >= 18) && (age <= 35)) && ((military = "yes") || (pushups >= 50))))
			cout << "Yes, " << name << ", you may apply." << endl;


It's supposed to read it as:
If sex is male and age is between 18 and 35 and previous military experience OR you can do more than 50 pushups.

Any ideas?

What's the type of variable "sex"?

With the first attempt the issue is that you need one more bracket pair to enclose the whole if clause.

With the last attempt change (military = "yes") to (military == "yes")

Also, this -> military = "yes" should probably be -> military == "yes"

I have sex as a string.

@ m4ster - This worked! Thanks so much!

Well, don't give all the credit to me... spaggy also pointed out this problem...

Ok I just have one more problem, which is my output. It's giving me the answer to each if statement. Is there a way I apply the else statement to all of them in order to only produce one output?

Else if should solve that

Edit: ah, I just saw that this is more or less what m4ster r0shi posted.

Don't worry, I won't bite you or anything... :)

That can be further simplified. Note that all conditions depend on age>=18.
