.写一个完整的程序放在代码段CODE_SEG，要求把数据段DATA_SEG中的DATA1和附加段EXTRA_SEG中DATA2相加，并把结果存放在DATA_SEG段中的SUM中。其中DATA1 、DATA2和SUM均为双精度数，DATA1赋值为7725，DATA2赋值为-2341。-. To write a complete program on the code segment CODE_SEG, requested that the data segment DATA_SEG in DATA1 and DATA2 add additional paragraphs EXTRA_SEG in, and the results stored in the SUM in the DATA_SEG paragraph. One DATA1, DATA2, and SUM are all double-precision number, DATA1 assignment for the 7725, DATA2 assignment to-2,341.
