Arrays

[Arrow]

When I do something like this in a method:
int a = 2;
if(variabel == a) {
...
}

it works, but Not when using arrays like this:
int *a = {1,2,3};
if(variabel == a[1]) {
.....
}
it just doesnt work in any way...anything special I need to know about arrays??

[HOS]

int *a = {1,2,3};

if you dont need to change the array you should be able to do something like

Code: Select all

int a[] = {1,2,3};

that worked for me, but i had compile errors using your syntax. another thing to remember is that arrays are 0-indexed

[Solar]

int *a = {1,2,3};
if(variabel == a[1]) {
.....
}

int *a is not an array of integers, but a pointer to one integer. Your compiler should give you at least a warning about this; GCC sure does.

Correct is:

Code: Select all

int a[] = {1,2,3};

It is correct that syntactically, "a" can be handled as a pointer-to-int (as in, e.g. *a+5, but you have to declare it correctly so the compiler knows what you're intending.
