#include<stdio.h>

void main()

{

int a[6][6],n,n1,i,sum=0;

printf("Enter the order of the matrix");

scanf("%d %d"'&n,&n1);

if(n==n1)

{

printf("Enter the matrix");

for(i=0;i<n;i++)

for(j=0;j<n;j++)

scanf("%d",&a[i][j]);

printf("The matrix is\n");

for(i=0;i<n;i++)

{

for(j=0;j<n;j++)

printf("%d\t",a[i][j]);

printf("\n");

}

for(i=0;i<n;i++)

sum+=a[i][i];

printf("Trace of the matrix is=%d",sum);

}

else

printf("Enter a square matrix\n");

}

Other than the fact that the program given will fail for a square matrix which is more than 6x6 (either with odd results or probably a sigsegv) and will fail to compile as a variable is not declared, it now calculates the trace of the given matrix, as calculating the trace requires a square matrix, why ask for both dimensions instead of just asking for the size of the square matrix?

What is matrix programming in C programming?

C Examples on Matrix OperationsA matrix is a rectangular array of numbers or symbols arranged in rows and columns. The following section contains a list of C programs which perform the operations of Addition, Subtraction and Multiplication on the 2 matrices. The section also deals with evaluating the transpose of a given matrix. The transpose of a matrix is the interchange of rows and columns.The section also has programs on finding the trace of 2 matrices, calculating the sum and difference of two matrices. It also has a C program which is used to perform multiplication of a matrix using recursion.C Program to Calculate the Addition or Subtraction & Trace of 2 MatricesC Program to Find the Transpose of a given MatrixC Program to Compute the Product of Two MatricesC Program to Calculate the Sum & Difference of the MatricesC Program to Perform Matrix Multiplication using Recursion
