# C Exercises: Search an element in a row wise and column wise sorted matrix

## C Array: Exercise-67 with Solution

Write a program in C to search for an element in a row wise and column wise sorted matrix.

**Visual Presentation:**

**Sample Solution:**

**C Code:**

```
#include <stdio.h>
// Function to search for an element in a sorted 2D matrix
int searchElement(int arr2D[4][4], int n, int x) {
int i = 0, j = n - 1;
// Loop to traverse the matrix diagonally
while (i < n && j >= 0) {
// If the element is found in the matrix
if (arr2D[i][j] == x) {
printf("\nThe element found at the position in the matrix is: %d, %d\n", i, j);
return 1;
}
// If the element is smaller, move down in the column
if (arr2D[i][j] < x)
i++;
// If the element is larger, move left in the row
else
j--;
}
printf("\nThe given element was not found in the 2D array.\n");
return 0;
}
int main() {
// Initializing a 4x4 2D array
int arr2D[4][4] = {
{15, 23, 31, 39},
{18, 26, 36, 43},
{25, 28, 37, 48},
{30, 34, 39, 50}
};
int v = 37;
// Printing the original 2D array in matrix form
printf("The given array in matrix form is:\n");
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
printf("%d ", arr2D[i][j]); // Print each element of the matrix
}
printf("\n");
}
// Printing the value for searching
printf("The given value for searching is: %d\n", v);
// Searching for the element in the 2D matrix
searchElement(arr2D, 4, v);
return 0;
}
```

Sample Output:

The given array in matrix form is : 15 23 31 39 18 26 36 43 25 28 37 48 30 34 39 50 The given value for searching is: 37 The element Found at the position in the matrix is: 2, 2

**Flowchart:**

**C Programming Code Editor:**

**Previous:** Write a program in C to count the number of inversion in a given array.

**Next:** Write a program in C to to print next greater elements in a given unsorted array. Elements for which no greater element exist, consider next greater element as -1.
