Move 0s at top of each column in a MxN array
Hello,
I have a matrix of NxM (the dimensions are set by the user) and I want a function to move 0s at the top of each column, and leave the rest integers as they are. Look at the example:
Attachment 15762
After the movement of 0s I want to have:
0 0 0 2 1
1 0 3 4 1
3 0 3 3 1
3 1 2 1 4
4 4 5 3 5
Someone please correct my zerototopMatrix function below:
Code:
#include <stdio.h> #include <stdlib.h>
#include <time.h>
void printMatrix(int (*arr), int rows, int cols,int level)
{
int i, j;
printf("\n");
printf("\n");
printf("The matrix elements are:\n ");
for (i = 0; i < cols+level; i++) {
printf("%d ", i+1);
}
printf("\n");
for (i = 0; i < (cols*2+1+level); i++) {
printf("-");
}
printf("-\n");
for (i = 0; i < rows+level; i++) {
printf("%d| ", i+1);
for (j = 0; j < cols+level; j++) {
printf("%d ", *(arr + i*cols + j));
}
printf("\n");
}
}
void zerototopMatrix(int (*arr), int rows, int cols,int level)
{
int i, j;
printf("\n");
printf("\n");
int count = 0,temp = 0;
for (j = 0; j < cols+level; j++) {
for (i = 0; i < rows+level; i++) {
if (*(arr + i*cols + j)==0)
{
(*(arr + i*cols + j)= (*(arr + count*cols + j)));
(*(arr + count*cols + j))=0;
count++;
}
}
}
}
int main() {
int number;
srand ( time(NULL) );
int level = 0;
int row,col,colors;
int points = 0;
printf("How many rows:\n");
scanf("%d", &row);
printf("How many columns:\n");
scanf("%d", &col);
printf("How many colors:\n");
scanf("%d", &colors);
int *arr = (int *)malloc(row * col * sizeof(int));
int i, j;
for (i = 0; i < row+level; i++)
for (j = 0; j < col+level; j++) {
number = rand() % colors ;
*(arr + i*col + j) = number;
}
printMatrix(arr, row, col,level);
printf("\n\nMove 0s to top:\n");
zerototopMatrix(arr, row, col,level);
printMatrix(arr, row, col,level);
free(arr);
return 0;
}
