Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.
Two-dimensional Arrays : :
The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.
To declare a two-dimensional integer array of size [x][y], you would write something as follows −
type arrayName [ x ][ y ];
Where type can be any valid C data type and arrayName will be a valid C identifier.
Below is the source code for C program to find Sum of upper triangular matrix which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C program to find Sum of upper triangular matrix */
#include <stdio.h>
#include <stdio.h>
int main()
{
int A[10][10],i,j,m,n;
int row, col, sum = 0;
printf("Enter no. of rows :: ");
scanf("%d", &m);
printf("\nEnter no. of cols :: ");
scanf("%d",&n);
printf("\nEnter values to the matrix :: \n");
for (i = 0; i < m; i++)
{
for (j = 0; j < n; j++)
{
printf("\nEnter a[%d][%d] value :: ",i,j);
scanf("%d", &A[i][j]);
}
}
printf("\nThe given matrix is :: \n\n");
for (i = 0; i < m; ++i)
{
for (j = 0; j < n; ++j)
{
printf("\t%d", A[i][j]);
}
printf("\n\n");
}
/*
* Finds sum of upper triangular matrix
*/
for(row=0; row<m; row++)
{
for(col=0; col<n; col++)
{
if(col>row)
{
sum += A[row][col];
}
}
}
printf("\nSum of upper triangular matrix = %d \n\n", sum);
return 0;
}
Output : :
/* C program to find Sum of upper triangular matrix */
Enter no. of rows :: 3
Enter no. of cols :: 3
Enter values to the matrix ::
Enter a[0][0] value :: 9
Enter a[0][1] value :: 8
Enter a[0][2] value :: 7
Enter a[1][0] value :: 6
Enter a[1][1] value :: 5
Enter a[1][2] value :: 4
Enter a[2][0] value :: 3
Enter a[2][1] value :: 2
Enter a[2][2] value :: 1
The given matrix is ::
9 8 7
6 5 4
3 2 1
Sum of upper triangular matrix = 19
Process returned 0
