I am currently working on an assignment to simulate how an operating system handles deadlocks.
Anyway, I am having difficulties creating a Matrix -- Does anyone have a preference that they use when creating one? I was trying to use a two-dimensional array, but I must admit it is not working very well. (As in when I pass it to a function).
I am also using irregular structures that I created on my own as objects in the matrix.
Thank you for your help in advance! =D
You can figure out how to pass arrays, simply by copy/pasting the declaration of the array you want to pass.
Eg
int matrix[10][20];
You would have a function
void foo ( int matrix[10][20] );
And you would pass the matrix to the function like so
foo ( matrix );
Accessing the array inside the function is identical to accessing the array outside the function. The only thing you can't do inside the function is sizeof(array) (you get the pointer size, not the array size).
In this respect, it's no different from how you would pass a scalar value to a function.
Now you can mess about expressing the function in alternative forms, like
void foo ( int matrix[][20] );
void foo ( int (*matrix)[20] );
but that's just extra work
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
You can pass matrices to a function using one dimensional array to simulate matrices:
example
int num_rows,num_columns,i,j;
double *mat;
printf("enter dimensions of matrix:");
scanf("%d %d",&num_rows,&num_columns);
mat=(double *)malloc(num_rows*num_columns*sizeof(double));
/*Entering values from stdin*/
for(i=0;i<num_rows;i++)
for(j=0;j<num_columns;j++)
scanf("%lf",&mat[i*num_columns+j]);
...........................
void show_matrix(double*mat,int numr,int numk)
.........
