Slip 22 - B) Write a menu driven program to perform the following operation on m*n Matrix 1. Find sum of non diagonal elements of matrix 2. Find sum of all odd numbers of matrix

Solution:


#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 --> sum of non diagonal elements\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++)
        {
            if(i!=j)
            {
                sum=sum+a[i][j];
            }
        }
    }    printf("\n sum of non digonal elements= %d",sum);
        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;
    }
}
