Hi there. I'm trying to make a program that allows the user to enter a 3x3 matrix but I can't even get the input right at the moment :S

Heres what I've done so far:

int main (void) {

	int status=0, i=0, j=0;

	int x[3][3];

	char line[100];

    

	      printf("Enter 3 x 3 matrix:\n");

		  

		      for(i=1; i<=3; i++) {

				  printf("Enter points of row %d:\n", i); 

				  for(j=0; j<=2; j++) {

					  while(1) {

					  

				      fgets(line, sizeof(line), stdin);

                      status = sscanf(line, "%d", &x[i][1+j]);

				      if (status==0) printf("Invalid point.\n");

					  else break;

				  }

			  }

		  }                   	  

	

	      printf("Data input:\n\n");

	     

		  for(i=1; i<3; i++) { 

			  for(j=0; j<2; j++) {

			  printf("%d\n", x[i][1+j]);

			  }

		  }

  

  return 0;

}

It needs to calculate the transpose of the matrix too, but actually getting the thing to input properly is my major concern right now.

Help please!

The indices on your array are from 0-2, not 1-3.
