TIA博途SCL编程学习20_换钱
1. 100元钞票，换成等值10元、5元、2元、1元的小钞票组合，每次换成40张，而且每种至少有1张。

2. 练习多重循环嵌套和二维数组的使用，用二维数组的列记录换法次数，行记录每一种钞票的张数。

.......

做了下：
x:=1;
f:=1;
WHILE x<=6 DO
    y:=1;
    WHILE y<=12 DO
        z:=1;
        WHILE z<=30 DO
            d:=1 ;
            WHILE d<=37 DO
                IF x+y+z+d=40 AND 10*x+5*y+2*z+d=100   THEN
                      arr1[f].a:=x;
                    arr1[f].b:=y;
                    arr1[f].c:=z;
                    arr1[f].d:=d;
                    f:=f+1;
                END_IF
                d:=d+1;
            END_WHILE
            z:=z+1;
        END_WHILE
        y:=y+1;
    END_WHILE
    x:=x+1;
END_WHILE
