Below is the program in C Language that will take decimal number as input. It will then call a function that will calculate the binary equivalent of the input decimal number. #include #include int i = 0; int b[10]; void main() { int dec; int* DecimalToBinary(int n); int *p, j; printf(“Enter a decimal integer = “); scanf(“%d”, &dec); p = DecimalToBinary(dec); printf(“Binary of given decimal integer = “); for (j=i; j>=0; j–) printf(“%d”, p[j]); printf(“\n”); getch(); } int* DecimalToBinary(int n) { while (n != 1) { b[i] = n % 2; n = n / 2; i++; } if (n...

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.
