How can i solve this matrix problem using recursion function in c?

I have already solved this problem using for loop.

Given an n x n matrix A. Here n is number of row and column. Write a recursive function to find the sum of the diagonal elements of A.

Example:

3 2 1
6 3 4
9 8 3

Output: 9


#include<stdio.h>

void main()
{
    int mat[12][12];
    int i,j,row,col,sum=0;
    printf("Enter the number of rows and columns for 1st matrix\n");
    scanf("%d%d",&row,&col);
    printf("Enter the elements of the matrix\n");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            scanf("%d",&mat[i][j]);
        }
    }

    printf("The matrix\n");
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("%d\t",mat[i][j]);
        }
        printf("\n");
    }
    //To add diagonal elements
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            if(i==j)
            {
                sum=sum+mat[i][j];
            }
        }
    }

    printf("The sum of diagonal elements of a square matrix = %d\n",sum);
}

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
