Input and Print a 2x2 Matrix in C

Problem:
Write a C program to take input for a 2x2 matrix and display the matrix.

Example:

Input:
1 2
3 4

Output:
1 2
3 4
  

🔍 Explanation:

• A 2x2 matrix has 2 rows and 2 columns.
• We use a 2D array matrix[2][2] in C to store the values.
• scanf() takes input from the user.
• printf() prints the matrix in proper format.

✅ C Program:

#include <stdio.h>

int main() {
    int matrix[2][2];

    // Taking input
    printf("Enter 4 elements of 2x2 matrix:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 2; j++) {
            scanf("%d", &matrix[i][j]);
        }
    }

    // Printing the matrix
    printf("The 2x2 matrix is:\n");
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 2; j++) {
            printf("%d ", matrix[i][j]);
        }
        printf("\n");
    }

    return 0;
}
  

📤 Output:

The 2x2 matrix is:
1 2
3 4
  

💡 Tips:

• Change the array size to create a 3x3 or 4x4 matrix.
• Nested loops are essential for matrix operations.
