c语言求定3*3矩阵中,主副对角线上所有元素之和答:int main() { int i,a[N][N] = {1,2,3,4,5,6,7,8,9};int major_diagonal = 0,assist_diagonal = 0;for(i = 0; i < N; ++i) { major_diagonal += a[i][i];assist_diagonal += a[i][N - 1 - i];} printf("主要对角线的和为:%d\n",major_diagonal);printf("...
如何用C语言编写矩阵运算的代码?答:C语言示例代码如下:include<stdio.h> int main(){int i,sumX=0,sumY=0,sum=0;int num[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}};for(i=0;i<5;i++){//计算对角线 sumX+=num[i][i];sumY+=num[5-i][i...
