- code this:#include void main(void) { int c =2 ^3; cout<< c; }Matrix Problem Code this in C Write a program that reads two matrices of integers. It then generates the sum, difference, and product of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements. To multiply a matrix by another matrix we need to do the "dot product" of rows and columns. The "Dot Product" is where we multiply matching members, then sum up: (1, 2, 3) • (7, 9, 11) = 1×7 + 2×9 + 3×11 = 58 We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the 3rd members (3 and 11), and finally sum them up. Use the following definitions:#define ROW 6#define COL 6void add(int matrixResult[][COL],int…

Number Converter Program as described in the UML has the following functionality.1. Read a number from the user and find its base. If number is exceeding the limit of 16-bits,ask user to re-enter the number. Use parameterized constructor Conversion(char *) toinitialize the data member.int FindBase(char []);There are a few assumptions. i) If all digits of a number are 0 or 1, the number is binary. For example, 1010 will beconsidered a Binary number only.ii) A hexa-decimal number must have letter A, B, C, D, E or F. Otherwise the number willnot be considered a hexa-decimal.iii) Decimal number must have minimum one digit greater than 7. Otherwise, the numbercan be considered as Octal if it does not meet the criteria in point no. i and ii.2. Converting the number to Binary if the number is not Binary.char * ToBinary(char *);3.

Matrices have numerous applications in computer systems. Matrix structures are examined in computer memory, graphics, and cryptography. The Hill cipher, for example, makes use of matrix inversions to encrypt and decrypt data. The intent of this problem is to develop a C++ program that computes and displays the inversion of a 2 x 2 matrix. A matrix is said to have the dimensions m x n if it has m rows and n columns. A square matrix has the same number of rows as columns, and is therefore said to have m x m dimensions. Matrix M shown below is an example of a 2 x 2 matrix. The inverse of a square matrix, M-1, is defined by the equation M(M-1) = I, where I is called the identity matrix. I is a square matrix that is all zeros except for ones along the main diagonal from the upper left corner to the lower right corner. I for a 2 x 2 matrix is: Multiplying a square matrix by its inverse will always…// add.ll define void @add(i32* %ptr1, i32* %ptr2, i32* %val) {ret void} Fill add.ll function to do the following operation: void add(int *ptr1, int *ptr2, int *val) { *ptr1 += *val; *ptr2 += *val; } This is the full question. It is related to LLVM. If it's going to help there is one more code given which is: #include <stdio.h> void add(int *ptr1, int *ptr2, int *val); int main(int argc, char **argv) {FILE *f = fopen(argv[1], "r");int a, b, c;fscanf(f, "%d %d %d", &a, &b, &c);add(&a, &b, &c);printf("%d %d\n", a, b);fclose(f); return 0;}
