Question

I understand that in C we can do

int foo[3];
foo[0]=1;
foo[1]=2;
foo[2]=3;

However in Interactive C, it gives me an error. I can only declare everything at once, such as

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

Anyone familiar with Interactive C knows why is this the case? Is that in IC, you cannot pass in value one by one at all?

Answer 1

I found out the reason it gave me an error is because the declared more int variables after the array assignment. For example,

...
foo[5] = 1;
foo[6] = 2;

int bar = 3;

This will not compile, it will highlight the “int bar” line and shows a syntax error.

seems like one cannot declare more variables with their types after the array assignment.

This might due to the fact that IC is an simplified version of C.
