定义一个正矩阵,求其对角线之和-搜答案-智慧作业帮

#include#includeconstintMAX=100000;intgcd(inta,intb){returna%b?gcd(b,a%b):b;}booldig(charx){returnx>

#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

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�� [][]�

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).

#includeintmain(){inta[5][5];for(inti=0;i<5;i++){for(intj=0;j<5;j++)scanf("%d",&a[i][j]);}ints=0;for

#include#definek3intmain(){intenter;//intk=3;intarr[k][k];inti,j,sum=0;for(i=0;i

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

#include <iostream>using namespace std;void main(){/* 变量定义与初始化

#includevoidmain(){int[3][3],sum=0;inti,j;printf("enterdata:\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,

#include"stdio.h"#defineN10intmian(){inta[N][N];inti,j,sum=0;for(i=0;i

voidmain(){inta[3][3]={1,3,5,7,9,11,13,15,17},s1=0,s2=0,i,j;for(i=0;i

可参考以下程序:inta[5][5];//5*5数组inti,x,y;//x,y是两个对角线元素的和.x=0;for(i=0;i

#includevoidmain(){inta[5][5]={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25},i,
