请生成一段C++代码，使其能够求解矩阵乘法

#include <stdio.h>

#define ROW1 2
#define COL1 3
#define ROW2 3
#define COL2 2

int main() {
int mat1[ROW1][COL1] = {{1, 2, 3}, {4, 5, 6}};
int mat2[ROW2][COL2] = {{7, 8}, {9, 10}, {11, 12}};
int result[ROW1][COL2] = {{0, 0}, {0, 0}};

for (int i = 0; i < ROW1; i++) {
for (int j = 0; j < COL2; j++) {
for (int k = 0; k < ROW2; k++) {
result[i][j] += mat1[i][k] * mat2[k][j];
}
}
}

printf("Result:\n");
for (int i = 0; i < ROW1; i++) {
for (int j = 0; j < COL2; j++) {
printf("%d ", result[i][j]);
}
printf("\n");
}

return 0;
}
