Question

Write a program in c to display the largest and smallest number from any 5 row by 5 column matrix. Initialize the matrix with random numbers between -20 and 20.

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
    srand(time(NULL));
    
    int arr[5][5];
    int n = 5, i, j;
    
    for(i = 0;i<n;i++){
        for(j = 0;j<n;j++){
            arr[i][j] = -20 + rand()%41;
            printf("%d ",arr[i][j]);
        }
        printf("\n");
    }
    
    int min = arr[0][0], max = arr[0][0];
    for(i = 0;i<n;i++){
        for(j = 0;j<n;j++){
            if(min > arr[i][j]){
                min = arr[i][j];
            }
            if(max < arr[i][j]){
                max = arr[i][j];
            }
        }
    }
    
    printf("\nLargest = %d\n",max);
    printf("Smallest = %d\n",min);

    return 0;
