引言: int a[10][3]={{50,51,52},{53,54,65},{77,81,29},{100,99,42},{33,41,51},{61,71,81},{91,20,23},{62,73,34},{25,26,42},{40,29,58}}, b[3][1]={{0.3},{0.3},{0.4}}, c[10][1], i,j,k; for(i=0; i<10;i ) for (j=0;j<2;j ) c=[i][j]=0; for(i=0;i<10;i ){ for(j=0,j<2;j ){ for(k=0;k<3;k ){ c[i][j] = (a[i][k]*b[k][j] ); } printf(" c[%d][%d] = %-2d ",i,j, c[i][j]); } printf("\n"); } 如提...我最近才剛學C ...還請多多包含 我想算出這樣的式子結果... 只是自己算出來的式子為何不能計算呢!? 希望有大大可以指點我 謝謝^^

8851167你好： 弄個較簡單的測試比較好著手，另外就是一步步的依照錯誤訊息 class="code"> int main(int argc, char* argv[]) { int a[2][2]={{3,5},{4,1}}; int b[2][2]={{1,2},{3,3}}; int c[2][21]; int i,j,k; for(i=0;i<2;i ) for (j=0;j<2;j ) c[i][j]=0; for(i=0;i<2;i ){ for(j=0;j<2;j ){ for(k=0;k<2;k ){ c[i][j] = (a[i][k]*b[k][j]); } printf(" c[%d][%d] = %-2d ",i,j, c[i][j]); } printf("\n"); } return 0; } 記得要看post規範哦!
