C Code to Illustrate the Concept of Unions - C Define the union named number with two variables j1 and j2. Define the union variable x. Take the value of two variables using dot operator(i.e. x.j1, x.j2) as input. Print values

Calculate Sum and Difference of Matrices - C Program calculates the sum & difference of the matrices. Code first reads 2 matrices and then performs both addition and subtraction of matrices. Sum of elements of matrix A and

Program Shows How a Pointer is Declared - There are several other things that we can do with "pointers", we have discussed them later in this guide. Now, we just need to know how to link a pointer to the 'Address of a Variable'.
