A symmetric matrix is a square matrix that is equal to its transpose. Let A be a symmetric matrix. Then, A = AT In this program, we need to check whether the given square matrix is symmetric or not. We will follow the steps given below. Step 1 – Accepts a square matrix as input Step 2 – Create a transpose of a matrix and store it in an array Step 3 – Check if input matrix is equal to its transpose or not If it is equal, then the input square matrix is symmetric. Here it goes… #include #include...

A transpose of a matrix is formed by turning all the rows of a given matrix into columns and vice-versa. The transpose of matrix A is written as AT Below is the program that will obtain transpose of 3 by 3 matrix. This program takes arr[3][3] matrix as input. It will then display its transpose matrix arrT[3][3]. #include #include void main(){ int arr[3][3], arrT[3][3]; int i,j; clrscr(); printf(“Enter the 3×3 matrix:\n”); for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf(“Enter the element arr[%d][%d] : “,i,j); scanf(“%d”,&arr[i][j]); } } for(i=0;i<3;i++) { for(j=0;j<3;j++) { arrT[j][i] = arr[i][j]; } } printf(“The transpose of the matrix is: \n”);...

An array is a collective name given to a group of similar variables. In this program we will accept two 2-D array (2 by 2 Matrix) as input from the user. This program will then perform addition of two 2 by 2 matrix. It will then display the result after adding two matrix. Here is the program for matrix addition. If you found this article useful, do post a comment. #include #include void main(){ int arr1[10][10], arr2[10][10]; int arr3[][3]={ {0,0,0}, {0,0,0}, {0,0,0} }; int i, j; clrscr(); printf(“Enter 3×3 array 1:\n”); for(i=0;i<3;i++){ for(j=0;j<3;j++){ printf(“Enter element %d x %d:”,i,j); scanf(“%d”,&arr1[i][j]); }...

The below mentioned program copies the content of one array name ‘source’ into another array named ‘dest’ in the reverse order. In case you have any queries related to the below mentioned program, please don’t hesitate to comment on this post. Your comments are always welcomed. #include #include void main(){ int source[100], dest[100],i,j,no; clrscr(); printf(“Enter the number of elements: “); scanf(“%d”,&no); for(i=0;i<no;i++){ printf(“Enter Source Array Element%d :”,i+1); scanf(“%d”,&source[i]); } for(i=0,j=no-1;i<no;i++,j–){ dest[j]=source[i]; } printf(“Destination array:\n”); for(i=0;i<no;i++){ printf(“%d\t”,dest[i]); } getch(); } Output: Enter the number of elements: 10 Enter Source Array Element1 :1 Enter Source Array Element2 :2 Enter Source Array Element3...
