    Expression Syntax Error in Turbo C

    Hi there,

    I am a novice programmer and have chosen C to begin with. This is a really really simple code where I am trying to change the fields of of an extern structure. When I compile it with turbo C. I get expression syntax error from the compiler on the only line of code.

    Following is the small piece of C code
    /*=================================*/
    Code:
    #include<stdio.h>
    
    struct {
        int status[2];
        float time[2];
        float state[4][2];
    } states = {{0,0},{0,0},{{1,2},{3,4},{5,6},{7,8}}};
    
    void main(void)
    {
    
    states.status = {1,1};
    
    }
    /*=================================*/

    I will really appreciate any kind of help.

    Thanking you in anticipation.

    Regards,
    Vivek.

    1. Never use void main.
    2.Turbo C is a fossil. If you've just started learning C, try your hands on some other compiler.
    3. "status" is an array, so you should use array subscripting to do anything with it. So the line
    Code:
    states.status = {1,1};
    needs array subscripting. After subscripting it, only one value can be assigned to it.
    [edit]
    By the way, you can see the FAQ for void main

    What does that mean exactly?
    And re arrays:
    Arrays can be initialized the way you do, but never assigned that way.
    Initialized is when they are first created; afterwards it's all assignment.

    I knew that I'll be misunderstood. I didn't know how to tell that but this is what I meant.
    For assigning both the array elements a 1 he should have done this
    Code:
    states.status[0] = 1;
    states.status[1]=1;
