How can a user entered row of 2 by 2 or a 3 by 3 matrix can be interchanged with another row of the same matrix in c language?

Question

Matrix is entered by the user.

Answer 1

Please clarify your question.

Answer 2

So you want to interchange two rows of the same matrix with each other?
Can you provide the sample output to understand better?

Answer 3

#include <stdio.h>

int main()
{
int rows = 3, cols = 3;
int matrix[rows][cols];

for(int i = 0; i < rows; i++)
{
for(int j = 0; j < cols; j++)
{
matrix[i][j] = i + j;
printf("%d ", matrix[i][j]);
}
printf("\n");
}

printf("\nInterchanging row 1 with row 2\n");
for(int i = 0; i < 1; i++)
{
for(int j = 0; j < cols; j++)
{
int temp = matrix[i][j];
matrix[i][j] = matrix[i+1][j];
matrix[i+1][j] = temp;
}
}

for(int i = 0; i < rows; i++)
{
for(int j = 0; j < cols; j++)
{
printf("%d ", matrix[i][j]);
}
printf("\n");
}
return 0;
}
