求一个5*5矩阵的对角线之和-搜答案-搜搜考试网

for(i=0;i=0;i--,j++)sum1=sum1+a[i][j];

#include#includevoidmain(){inta[3][3];inti,j;//i为行j为列intsum=0;intsum1=0;//输入for(i=0;i

#includevoidmain(){inti,j,a[3][3],sum=0;for(i=0;ifor(j=0;jscanf("%d",&a[i][j]);for(i=0;isum+=a[i][i]

intnSum=0;for(inti=0;i

1+5+9+7+3

晕.main(){inti,j;inta[3][3];intresult=0;for(i=0;i

intmatrix(int**aintra,intca){intsum=0;for(inti=0;i再问：��д�� [][]�

#includevoidmain(){inta[3][3];inti,sum1,sum2;for(i=0;i

对角线元素之和可以调用库函数trace,也就是矩阵的迹定义了矩阵A后,直接调用函数trace(A).

intmain(){inta[5][5],i,j,sum1,sum2;sum1=0;sum2=0;for(i=0;i

#includeusingnamespacestd;voidmain(){intCArray[5][5];inti,j;intsum=0;cout

#include#defineN6main(){inti,j,n=1,s=0,m=0,a[N][N];for(i=0;i

用C语言实现,代码如下#include"stdio.h"#defineM3//矩阵阶数voidmain(){inta[M][M],i,j,sum=0;printf("请输入%d*%d矩阵：\n",M,
