编写一个 C 程序来执行 3X3 矩阵运算
问题
运行时输入任意9个数字,用C语言将数字按行、列、对角线相加
算法
Step 1: Declare 9 variablesStep 2: enter 9 numbers at runtime
Step 3: store the numbers in 3 X 3 matrix form
//xyz
p q r
a b c
Step 4: Do row calculation: add all the numbers in a row and print
// (x+y+z),(p+q+r),(a+b+c)
Step 5: Do column calculation: add all the numbers in a Column and print
//(x+p+a)(y+q+b)(z+r+c)
Step 6: Do Diagonal Calculation: add the numbers in diagonal and print
//(x+q+c),(a+q+z)
程序
#include<stdio.h>输出结果int main(){
int x,y,z,p,q,r,a,b,c;
printf(“enter any 9 numbers :\n");
scanf(“%d%d%d%d%d%d%d%d%d",&x,&y,&z,&p,&q,&r,&a,&b,&c);//读取所有 9 个整数
printf(“%d %d %d\n",x,y,z);
printf(“%d %d %d\n",p,q,r);
printf(“%d %d %d\n",a,b,c);
printf(“Row total:%d %d %d\n",(x+y+z),(p+q+r),(a+b+c));//行计算
printf(“column total: %d %d %d\n",(x+p+a),(y+q+b),(z+r+c));//列计算
printf(“diagonal total :%d %d\n",(x+q+c),(a+q+z));//对角线计算
return 0;
}
enter any 9 numbers :2 4 6 3 5 7 8 9 2
2 4 6
3 5 7
8 9 2
Row total:12 15 19
column total: 13 18 15
diagonal total :9 19
