我的理解,你是一個(gè)9*9的矩陣,那么:dim s as integerdim i as integerdim j as integerdim d(9,9) as integer'假設(shè)二維數(shù)組為d,且主對(duì)角線元素的值為1-9s=0for i=1 to 9 for j=1 to 9if i=j then s = s...是我的錯(cuò)，應(yīng)該是3*3的，第一行123 第二行 456 第三行789哦,這個(gè)這樣:dim s as integerdim i as integerdim j as integerdim d(3,3) as integerdim n as integer'先構(gòu)成矩陣的二維數(shù)組n=0for i=1 to 3for j=1 to 3 n = n + 1 d(i,j) = n next jnext i'輸出矩陣For i = 1 To 3For j = 1 To 3Print d(i, j),Next jPrintNext i'計(jì)算主對(duì)角線和并輸出s = 0For i = 1 To 3For j = 1 To 3 If i = j Then s = s + d(i, j)Next jNext iPrint s
