To find the greatest element in each row of a two-dimensional array

#include <stdio.h>

int main() {

int rows, cols;

 printf("Enter the number of rows: ");

scanf("%d", &rows);

 printf("Enter the number of columns: ");

scanf("%d", &cols);

int matrix[rows][cols];

// Input elements into the 2D array

printf("Enter the elements of the 2D array:\n");

for (int i = 0; i < rows; i++) {

for (int j = 0; j < cols; j++) {

scanf("%d", &matrix[i][j]);

}

}

 // Find the greatest element in each row and print

for (int i = 0; i < rows; i++) {

int maxElement = matrix[i][0];

for (int j = 1; j < cols; j++) {

if (matrix[i][j] > maxElement) {

maxElement = matrix[i][j];

}

}

printf("The greatest element in row %d is: %d\n", i + 1, maxElement);

}

 return 0;

}

the program works:

1. It takes input for the number of rows and columns for the 2D array.

2. It initializes a 2D array named ‘ matrix ‘ with the specified dimensions.

3. It takes input for the elements of the 2D array.

4. It then iterates through each row of the matrix, finding the maximum element in each row and printing it. The ‘ maxElement ‘variable is used to keep track of the greatest element.

This program will output the greatest element in each row of the 2D array.
