Write a C program to find the minimum and maximum value of each column in a given matrix.
#include <stdlib.h>
int main() {
int row, col, **data, i, j, min, max;
/* get the number of rows and column from the user */
printf("Enter the no of rows and columns:");
scanf("%d%d", &row, &col);
/* dynamically allocate memory to store array entries */
data = (int **)malloc(sizeof (int) * row);
for (i = 0; i < col; i++)
data[i] = (int *)malloc(sizeof (int) * col);
/* get the inputs entries */
printf("Enter your inputs:");
for (i = 0; i < row; i++)
for (j = 0; j < col; j++)
scanf("%d", &data[i][j]);
/* find the min and max element in each column */
for (i = 0; i < col; i++) {
min = data[0][i];
max = data[0][i];
for (j = 0; j < row; j++) {
if (data[j][i] < min)
min = data[j][i];
if (data[j][i] > max)
max = data[j][i];
}
printf("Column %d: Max: %d Min:%d\n", i+1, max, min);
}
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
Enter the no of rows and columns:3 3
Enter your inputs:
10 20 30
40 50 60
15 25 35
Column 1: Max: 40 Min:10
Column 2: Max: 50 Min:20
Column 3: Max: 60 Min:30
Enter the no of rows and columns:3 3
Enter your inputs:
10 20 30
40 50 60
15 25 35
Column 1: Max: 40 Min:10
Column 2: Max: 50 Min:20
Column 3: Max: 60 Min:30
