怎样用C语言编程计算二维数组每一行和每一列数的和? 麻烦测试好了发我...答:95, 72, 81, 90, 86, 82,96, 80, 90, 92, 84, 88,88, 80, 78, 86, 84, 80,77, 76, 86, 88, 80, 85 };void main(void){ float sum1[5] = {0,0,0,0,0};//行的和 float sum2[6] = { 0, 0, 0, 0, 0 ,0};//列的和 for (int i = 0; i < 5; i+...
c语言输出二维数组中指定列的和 如输入二维数组: 1 2 3 4 5 6 7 8...答:对应的行和列你可以自己修改,同时初始化数组的也要修改。include <stdio.h> define COL 4 define ROW 4 int main(){ int array[ROW][COL]={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16};int pos;for(int i = 0;i<ROW;i++){ for(int j = 0; j<COL;j++){ printf("%d...
c语言求二维数组中所有元素的和答:int main(void){ int ar[3][3]= { {1,2,3},{4,5,6},{7,8,9} };int num;int i,j;int k = 0,sum=0;int (*ptr)[3];ptr = ar;num = sizeof(ar) / sizeof(ar[0]);printf("num = %d\n",num);printf("%d\n",*(*(ptr +0) + 1));for(i = 0; i < 3...
C语言中,求二维数组的每一行的和与平均值答:include <stdio.h>#include <string.h>int main(){int i=0,j=0,total=0;float avr=0;int a[3][3] = {{1,2,3},{4,5,6},{7,8,9}};for (i=0;i<3;i++){total=0;for (j=0;j<3;j++){total +=a[i][j];}avr = (float)(total/3.0);printf("sum[%d] aver[%...
用C语言编一个程序求一个二维数组各行数求和答:int main(){ int a[5][5] = {{0, 1, 2, 3, 4}, {1, 2, 3, 4, 5}, {2, 3, 4, 5, 6}, {3, 4, 5, 6, 7}, {4, 5, 6, 7, 8}};for (int i = 0; i < 5; ++i){ int sum = 0;for (int j = 0; j < 5; ++j){ sum = sum + a[i][j];}...
