求一个5*5矩阵的对角线元素的和.-搜答案-神马作文网

#include"stdio.h"#defineM5//矩阵阶数voidmain(){inta[M][M],i,j,sum=0;printf("请输入%d*%d矩阵：\n",M,M);for(i=0;

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

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

intnSum=0;for(inti=0;i

#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

楼上的不智能啊,看我的：publicclasshaha{publicstaticvoidmain(String[]args){\x05inta[][]=newint[5][5];\x05intnum_

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

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,
