Find maximum and minimum in a matrix

Posted on Apr 25, 2020

C program to find maximum and minimum in a matrix.

Program

#include<stdio.h>
#include<conio.h>
#define MAX 10

void main()
{
	int mat[MAX][MAX];
    int row, col;
    int i, j, max, min;

    printf("Enter the number of rows\t:");
    scanf("%d",&row);
    printf("Enter the number of columns\t:");
    scanf("%d",&col);

    printf("Enter the elements\n");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("Element [%d][%d]\t:",i,j);
            scanf("%d",&mat[i][j]);
            if(i==0 && j==0)
            {
                max = mat[0][0];
                min = mat[0][0];
            }
            if(min > mat[i][j])
            {
                min = mat[i][j];
            }
            if(max < mat[i][j])
            {
                max = mat[i][j];
            }
        }
    }

    printf("\n\nMatrix entered is\n");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("%d\t",mat[i][j]);
        }
        printf("\n");
    }

    printf("\n\nMaximum Value\t:%d",max);
    printf("\nMinimum Value\t:%d",min);

    getch();
}

Output

Enter the number of rows        :3
Enter the number of columns     :4
Enter the elements
Element [0][0]  :23
Element [0][1]  :34
Element [0][2]  :45
Element [0][3]  :54
Element [1][0]  :32
Element [1][1]  :12
Element [1][2]  :45
Element [1][3]  :67
Element [2][0]  :87
Element [2][1]  :56
Element [2][2]  :43
Element [2][3]  :32


Matrix entered is
23      34      45      54
32      12      45      67
87      56      43      32


Maximum Value   :87
Minimum Value   :12
