    Structure of arrays

    Hi,

    I have a structure of arrays such as:

    Code:
    typedef struct {
    	double array1[10];
    	double array2[10];
    	double array3[10];
    } data_array_struct;
    How do I access the elements of the arrays?

    I've tried to assign values using something like
    Code:
    data_array_struct.array1[i]=5;
    but the compilers says that there is "expected identifier or ( before [ token."

    Thanks!

    "data_array_struct" is the name of the typedef. You need a real instance:
    Code:
    data_array_struct  example;
    example.array1[0] = 5.0;
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge
