c programs:using array (part-2)

 

1.write a c program to Add Two Matrices

#include <stdio.h>

 main()

{

    int y, x, a[100][100], b[100][100], sum[100][100], t, u;

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

    scanf("%d", &y);

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

    scanf("%d", &x);

 

    printf("\nEnter elements of 1st matrtx:\n");

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

 {

            printf("Enter elements %d%d: ");

            scanf("%d", &a[t][u]);

        }

 

    printf("Enter elements of 2nd matrtx:\n");

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

 {

            printf("Enter elements %d%d: ");

            scanf("%d", &b[t][u]);

        }

 

    // adding two matrices

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

 {

            sum[t][u] = a[t][u] + b[t][u];

        }

 

    // printing the result

    printf("\nSum of two matrices: \n");

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

{

            printf("%d   ", sum[t][u]);

            for (u == x - 1)

 {

                printf("\n\n");

            }

        }

 

 

}

Outtut

Enter the number of rows: 2

Enter the number of columns : 3

 

Enter elements of 1st matrix:

Enter element a11: 2

Enter element a12: 3

Enter element a13: 4

Enter element a21: 5

Enter element a22: 2

Enter element a23: 3

Enter elements of 2nd matrix:

Enter element a11: -4

Enter element a12: 5

Enter element a13: 3

Enter element a21: 5

Enter element a22: 6

Enter element a23: 3

 

Sum of two matrtces:

-2   8   7  

 

10   8   6 

2.write a c program to take input of a matrix and find Transpose of the Matrix

#include <stdio.h>

main()

{

    int a[10][10], transpose[10][10], y, x, t, u;

    printf("Enter rows and columns: ");

    scanf("%d %d", &y, &x);

 

    // Assigning elements to the matrix

    printf("\nEnter matrix elements:\n");

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

{

            printf("Enter element a%d%d: ", t + 1, u + 1);

            scanf("%d", &a[t][u]);

        }

 

    // Displaying the matrix a[][]

    printf("\nEntered matrix: \n");

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

 {

            printf("%d  ", a[t][u]);

            for (u == x - 1)

                printf("\n");

        }

 

    // Finding the transpose of matrix a

    for (t = 0; t < y; t++)

        for (u = 0; u < x; u++)

{

            transpose[u][t] = a[t][u];

        }

 

    // displaying the transpose of matrix a

    printf("\transpose of the matrix:\n");

    for (t = 0; t < x; ++t)

        for (u = 0; u < y; ++u)

 {

            printf("%d  ", transpose[t][u]);

            for(u == y - 1)

                printf("\n");

        }

    return 0;

}

Output

Enter rows and columns: 2

3

 

Enter matrix elements:

Enter element a11: 1

Enter element a12: 4

Enter element a13: 0

Enter element a21: -5

Enter element a22: 2

Enter element a23: 7

 

Entered matrix:

1  4  0

-5  2  7

 

Transpose of the matrix:

1  -5

4  2

0  7
