c语言从键盘上输入两个2*3的矩阵求和

以下是从键盘上输入两个2*3的矩阵并求和的C语言代码示例：

#include <stdio.h>

int main() {
    int A[2][3], B[2][3], C[2][3];  // 定义两个2*3矩阵和它们的和矩阵C

    // 输入第一个矩阵A
    printf("Enter the elements of matrix A:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 3; j++) {
            scanf("%d", &A[i][j]);
        }
    }

    // 输入第二个矩阵B
    printf("Enter the elements of matrix B:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 3; j++) {
            scanf("%d", &B[i][j]);
        }
    }

    // 计算和矩阵C
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 3; j++) {
            C[i][j] = A[i][j] + B[i][j];
        }
    }

    // 输出和矩阵C
    printf("The sum of the two matrices is:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 3; j++) {
            printf("%d ", C[i][j]);
        }
        printf("\n");
    }

    return 0;
}

运行示例：

Enter the elements of matrix A:
1 2 3
4 5 6
Enter the elements of matrix B:
6 5 4
3 2 1
The sum of the two matrices is:
7 7 7
7 7 7
