7. C Program to find multiplication of two matrices
This C program will read two matrices and make a third matrix, which will contain the multiplication of both input matrices.
8. C Program to print lower diagonal of a matrix.
This C program will read a square matrix and print its lower diagonal.

List of other C programs

1. C program to declare memory for an integer variable dynamically.
Dynamic Memory Allocation Example: In this C program, we are will declare an integer pointer and allocate memory for an integer variable at run time using malloc().
2. C program to read and print name, where memory for variable should be declared at run time.
Dynamic Memory Allocation Example: In this C program, we will declare memory character array (to read name) at run time, will read name and print the string.
3. C program to find sum of array elements using Dynamic Memory Allocation.
Dynamic Memory Allocation Example: In this C program, we will declare memory for array elements (limit will be at run time) using malloc(), read element and print the sum of all elements along with the entered elements.
4. C Program to find the sum of digits of a number until a single digit is occurred.
C Program to find the sum of digits of a number until a single digit is occurred (without using recursion or iterative(loop) statements).
5. C program to find class of an IP Address.
This program will print the class of a given (user input) IP address.
