设BUF数据区中n个无符号字节数，试计算这些数之和，并以以下形式显示：d0+d1+…+dn-1=S
其中di为第i个数的十进制表示，S为和值的十进制表示。编写程序，要求将十进制数的显示使用子程序SUB1实现，求和工作用子程序SUB2实现。上机调试程序，检查程序正确性,BUF data area located in the n-byte unsigned number, the number of test and calculation of these and the following form: d0+ d1+ ...+ dn-1 = S in which di is the first i number of decimal, S for and that the decimal value. Programming, called for the display of a decimal number to achieve the use of subroutine SUB1, SUB2 summation subroutine to achieve with the work. Debugger on the machine to check the correctness of the procedure
