windlx实现俩个矩阵相乘的完整代码

好的，以下是一个实现两个矩阵相乘的完整代码：

#include <stdio.h>

int main()
{
    int row1, col1, row2, col2, i, j, k;
    float a[100][100], b[100][100], c[100][100], sum;

    printf("Enter the number of rows and columns of matrix 1: ");
    scanf("%d %d", &row1, &col1);

    printf("Enter the elements of matrix 1:\n");
    for(i=0; i<row1; i++)
    {
        for(j=0; j<col1; j++)
        {
            scanf("%f", &a[i][j]);
        }
    }

    printf("Enter the number of rows and columns of matrix 2: ");
    scanf("%d %d", &row2, &col2);

    if(col1 != row2)
    {
        printf("Error! The number of columns of matrix 1 should be equal to the number of rows of matrix 2.");
        return 0;
    }

    printf("Enter the elements of matrix 2:\n");
    for(i=0; i<row2; i++)
    {
        for(j=0; j<col2; j++)
        {
            scanf("%f", &b[i][j]);
        }
    }

    // Multiplying matrices a and b and storing the result in matrix c
    for(i=0; i<row1; i++)
    {
        for(j=0; j<col2; j++)
        {
            sum = 0;
            for(k=0; k<col1; k++)
            {
                sum += a[i][k] * b[k][j];
            }
            c[i][j] = sum;
        }
    }

    // Printing the result matrix c
    printf("The result of matrix multiplication is:\n");
    for(i=0; i<row1; i++)
    {
        for(j=0; j<col2; j++)
        {
            printf("%.2f ", c[i][j]);
        }
        printf("\n");
    }

    return 0;
}

该程序首先要求用户输入两个矩阵的行列数和元素，然后通过三个嵌套的循环实现矩阵相乘，并将结果存储在一个名为c的矩阵中。最后，程序打印出结果矩阵c。
