求一个3*3的整形矩阵对角线元素之和

#includemain(){\x09inta[3][3],i,j,sum=0;\x09printf("请输入数组元素：（3*3）\n");\x09for(i=0;i

#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]

publicclassGetSum{/***@paramargs*/publicstaticvoidmain(String[]args){//TODOAuto-generatedmethodstubi

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

intget_max(inta[4][4]){inti,j;intmax=-0xfffffff;for(i=1;i

#include#includeintmain(){inta[3][3]={{1,2,3},{4,5,6},{7,8,9}};intcol[3]={0};//hangintrow[3]={0};//l

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).

先收藏,等一会在弄.#include#includeintmain(){inti,j,m=0,a[3][3];printf("请输入9个整数\n");for(i=0;i再问：好的，先谢了

#includevoidmain(){inta[3][3],i,j,sum=0;cout

#includeintmain(){intarray[3][3],sum;inti,j;for(i=0;i{for(j=0;j{scanf("%d",&array[i][j]);}}sum=array

本人测试通过,如有问题可以联系我.#includeintmain(){intA[3][3];inti,j;printf("请输入3*3矩阵的值,9个数据一起输入,中间以空格隔开,例如586:\n");

#includeintmain(){floatst[3][3],sum=0;inti,j;for(i=0;ist[i][j];for(i=0;i

是不是要这样啊.#includeintmain(){inta[3][4]={1,2,3,4,5,6,7,8,9,0,1,2};intb[3][4]={11,21,13,14,51,61,17,18

main(){inta[3][3]={{1,2,3},{4,5,6},{7,8,9}}inti,j;intsum=0,s=0;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,

voidmain(){inta[4][4]={1,2,3,4,5,6,7,8,9,0,11,12,13,14,15,16};intmin,max;inti,j;min=max=a[0][0];for(
