Q1. Write a C program to display multiplication table of a given input number [15 Marks]

#include <stdio.h>

int main() {

    int num, i = 1;

    printf("

    Enter any Number:");

    scanf("%d", &num);

    printf("Multiplication table of %d: ", num);

        while (i <= 10) {

        printf("

        %d x %d = %d", num, i, num * i);

        i++;

    }

    return 0;

}

Q2. Write a menu driven program to perform the following operation on m*n

 Matrix [25 Marks]

1. Display transpose of a matrix

2. Calculate sum of all odd elements of matrix

#include <stdio.h>

void main()

{

    int a[10][10], transpose[10][10], r, c, i, j,sum=0, fig_code;

    printf("Enter rows and columns of matrix: ");

    scanf("%d %d", &r, &c);

    // Storing elements of the matrix

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

    for(i=0; i<r; ++i)

        for(j=0; j<c; ++j)

        {

            printf("Enter element a%d%d: ",i+1, j+1);

            scanf("%d", &a[i][j]);

        }

    printf("-------------------------\n");

    printf(" 1 --> Transpose\n");

    printf(" 2 --> Sum of odd elements\n");

    printf("-------------------------\n");

    printf("Enter the Figure code\n");

    scanf("%d", &fig_code);

    switch(fig_code)

    {

    

    case 1:

        for(i=0; i<r; ++i)

        for(j=0; j<c; ++j)

        {

            transpose[j][i] = a[i][j];

        }

        printf("\nTranspose of Matrix:\n");

       for(i=0; i<c; ++i)

        for(j=0; j<r; ++j)

        {

            printf("%d  ",transpose[i][j]);

            if(j==r-1)

                printf("\n\n");

        }

        break;

    case 2:

        

        for(i=0; i<r; ++i)

        for(j=0; j<c; ++j)

        {

            if(a[i][j]%2!=0)

                  sum=sum+a[i][j];

        }

        printf("\n sum of odd elements= %d",sum);

        break;

    

    default:

        printf("Error in figure code\n");

        break;

    }
