CLEAR P = 0 FOR N = 1 TO 49 IF N>10 EXIT ENDIF IF MOD (N,2) = 0 P = P+N ENDIF ENDFOR "P=" ,P RETU

题目

CLEAR P = 0 FOR N = 1 TO 49 IF N>10 EXIT ENDIF IF MOD (N,2) = 0 P = P+N ENDIF ENDFOR "P=" ,P RETU
这个程序的意义和算法是什么?

答案

CLEARP = 0 FOR N = 1 TO 49 IF N>10 EXIT ENDIF IF MOD (N,2) = 0 P = P+N ENDIF ENDFOR "P=" ,P RETU求10以内（含10）的偶数和算法就是从1开始逐个判断每个数是否超过10,如果超过就结束,然后判断是否为偶数,如果为...
