[Dev-C++] problem with scanf

[Mike S. <fre...@ho...>]

How come in the following code, the second scanf is skipped?

int main()
{
    /* Declare variables for main() */
    int count;
    float x, y;
    char cmd, cont;

    /* Use array symb[] for extended ASCII characters */
    char symb[] = { 201, 187, 200, 188, 199, 182, 186, 205, 196 };

    /* Infinite loop, using break; to stop */
    while(1)
    {
    printf( "\n%c", symb[0] );
    for ( count = 0; count < COL; count++ )
        printf( "%c", symb[7] );
    printf( "%c", symb[1] );
    printf( "\n%c           Calculator v1.02               %c",
        symb[6], symb[6] );
    printf( "\n%c", symb[4] );
    for ( count = 0; count < COL; count++ )
        printf( "%c", symb[8] );
    printf( "%c", symb[5] );
    printf( "\n%c This program is a small little DOS       %c",
        symb[6], symb[6] );
    printf( "\n%c calculator. When entering commands,      %c",
        symb[6], symb[6] );
    printf( "\n%c please enter them like the following,    %c",
        symb[6], symb[6] );
    printf( "\n%c otherwise it will not work.              %c",
        symb[6], symb[6] );
    printf( "\n%c Example: 12 + 13                         %c",
        symb[6], symb[6] );
    printf( "\n%c Keep in mind that * is multiplication,   %c",
        symb[6], symb[6] );
    printf( "\n%c and that / is division.                  %c",
        symb[6], symb[6] );
    printf( "\n%c", symb[2] );
    for ( count = 0; count < COL; count++ )
        printf( "%c", symb[7] );
    printf( "%c", symb[3] );
    printf( "\nEnter equation >> ");
    scanf( "%f %c %f", &x, &cmd, &y );

    /* Determine which operation to execute */
    if ( cmd == '+' )
        add( x, y );
    else if ( cmd == '-' )
        sub( x, y );
    else if ( cmd == '*' )
        mult( x, y );
    else if ( cmd == '/' )
        div( x, y );
    else
        printf( "\n%f %c %f is not a valid equation. ", x, cmd, y );

    x = 0;
    y = 0;
    cmd = 0;

    printf( "\nContinue? (Y/n) >> ");  /* This scanf is skipped */
    scanf( "%c", &cont );

    /* If statement used to break infinite loop */
    if ( cont == 'n' || cont == 'N' )
        break;
    else;
    }

    printf( "\n\n" );
    system( "pause" );
    return 0;
}
