y+=ySpeed; //这里要考虑对角线不标准情况,比如3*4的矩形 //对角线的最后一位可能不是右下角的坐标,直接强制指向右下角坐标 if(x == col-1 && y != row-1 || x != col-1 && y == row-1) { x = row-1; y = col -1; } } printf("主对角线之和为:%d\n",numA); intnumB = 0...
以下是一个简单的C++程序,用于计算给定二维数组中主对角线和次对角线元素的和: ```c++ #include <iostream> using namespace std; int main() { int n; cout << "请输入方阵的阶数:"; cin >> n; int a[n][n]; cout << "请输入方阵的元素:" << endl; for (int i = 0; i < n; i++)...
int sum1 = 0,sum2 = 0;for(i = 0; i < N; ++i) { sum1 += a[i][i];sum2 += a[i][N - 1- i];} cout << "主对角线之和：" << sum1 << endl;cout << "次对角线之和：" << sum2 << endl;
编写函数，求出⼆维数组主对⾓线、次对⾓线以及周边元素之和。要求：⼆维数组的⾏数、列数、数组元素在main函数中由键盘输⼊。#include <stdio.h> int main(){ int row,col;printf("请输⼊“⾏数”和“列数”：");scanf("%d,%d",&row,&col);printf("请为%d*%d数组赋值：\n",row,...
