    error: expected identifier or ( before { token '{ '

    I can't figure out why my code will not compile.
    The error listed above is the only error shown on the terminal.
    I have tried taking the ';' after the main(void) statement (as suggested on similar posts) but this just leads to more compilation errors.
    Does anybody have any ideas???

    Code:
    #include <stdio.h>
    
    
    int main(void);
    {
    double change ; 
    int quater =0 , dime =0 , nickel =0 , penny =0 ;
    printf("how much change is owed?\n");
    scanf("%lf" , &change);
    do
    {
        if (change >= 0.25);
        {
        quarter = quarter++ ;
        change = (change - 0.25);
        }
        else if (0.25 > change >= 0.1);
        {
        dime = dime++ ;
        change = (change - 0.1);
        }
        else if (0.1 > change >= 0.05);
        {
        nickel = nickel++ ;
        change = (change - 0.05);
        }
        else if (0.05 > change >= 0.01);
        {
        penny = penny++ ;
        change = (change - 0.01);
        }
    }
    while (change > 0);
    printf("the number of quarters is: %f\n" , &quarter);
    printf("the number of dimes is: %f\n" , &dime);
    printf("the number of nickels is: %f\n" , &nickel);
    printf("the number of pennys is: %f\n" , &penny);
    }

    The semi-colon after "int main(void)" is a mistake. If you read the errors after removing this, they should have described the problem.

    Also, the semi-colons after each "if()" is also wrong.

    Code:
    int quater =0
    
    // ...
    
     quarter = quarter++ ;
    Check your spelling. And the increment can be simplified to just:

    Code:
    quarter++;

    Then you'll need to deal with those other errors as well (there are quite a few errors in your code). The semicolon is wrong and needs to be removed.

    There are also several warnings that will need to be dealt with. I suggest you start compiling more often and fixing any warnings or errors before proceeding then you won't have so many error/warning messages to deal with at one time.

    It actually needs to be just
    Code:
    quarter++;
    or possibly
    Code:
    quarter = quarter + 1;
    Learned that here myself

    Not exactly

    You implied that this would still be permissible:
    Code:
    quarter = quarter++ ;
    It's not.

    Ah, poor wording on my part. Point well made.
