The issue with c++ is that there are a lot of nuances to it that gives it a steeper learning curve. As a result, one is a lot more error-prone when writing c++ code.

Regarding the assignment inside a conditional, here's random example code where it might be used:

char[] str = "Hello TeamLiquid!"
char c;
for (int i = 0; (c=str[i]) != 0; i++) {
printf("Letter: %c", c);
}

From a stylistic point of view, I don't think it's usually a particularly good idea, but it would be inconsistent to treat the assignment differently just because it was placed inside a conditional statement.

Huh that does make a lot of sense actually lol. I'm just used to java where if the if() statement doesn't resolve to a boolean it doesn't compile. C++ is nice and I like the fact that you have more freedom and it compiles directly to machine language and all, but some things about it just frustrate me. Like the fact that you can't declare an array without having a definite size for it ( yes I tried using extern.)

Also thanks a ton to everyone who helped me out. You guys rock .

oh and Sonovbob didnt catch the error. Sorry aethereal. He found another error though .

nah C++ is pretty easy, although nowadays I suggest you learn Java or C#

EDIT: Although, if I recall correctly C# can execute up to 40 times slower than C++, and the JVM means Java is slower as well (but you would learn the details yourself in a Java course). Of course, efficiency usually won't matter too much... though I think most games are not made with Java/C# (WoW for instance is written in C++), but you would use a lot of C# and Java in other programming jobs.

You can use vectors if you want to implement dynamic arrays, or use pointers, like:

int *ptr;
ptr = new int[5];
...
int *ptr2 = new int[10];
for ( ... ) ptr2[i] = ptr[i];
delete[] ptr;
