How to print out the output from each process in MPI programing

Hello everyone,
I have a 2d dynamic array and I broadcasted it to all processors. I was wondering how I can print the data from each process?
I want some thing like
Process 1
Print matrix
Process 2
Print matrix,
I would be really grateful if you can help me with an example.

What I have tried:

for (int i = 0; i < n_elem; i++)
	{
		MPI_Bcast((int **)&(connectivity[i][0]), 4, MPI_INT, 0, MPI_COMM_WORLD);
	}


	for (int i = 0; i < n_node; i++)
	{
		MPI_Bcast((double **)&(coordinate[i][0]), 4, MPI_DOUBLE, 0, MPI_COMM_WORLD);
	}

	MPI_Barrier(MPI_COMM_WORLD);


	printf("process %d prainting connectivity:\n", myrank);

	for (int i = 0; i < n_node; i++)
	{
		for (int j = 0; j < col; j++)
			printf("%d \t", connectivity[i][j], myrank);
		printf("\n");
	}


	printf("process %d prainting coordinate:\n", myrank);

	for (int i = 0; i < n_node; i++)
	{
		for (int j = 0; j < col; j++)
			printf("%g \t", coordinate[i][j], myrank);
		printf("\n");
	}

	MPI_Barrier(MPI_COMM_WORLD);
