C Program to Multiply two Matrices by Passing Matrix to a Function In this example, you'll learn to multiply two matrices and display it using user defined function. To understand this example, you should have the knowledge of the following C programming topics: C Arrays C Multidimensional Arrays Pass arrays to a function in C This program asks the user to enter the size of the matrix rows and column.

A matrix that contains the same number of rows and columns then it is called a square matrix. Matrix is used to store a group of related data. Some of the programming languages are used to support matrices as a data type that offers more flexibility than a static array. Instead of storing the values in a matrix, it can be stored as an individual variable, a program can access and perform operations on the data more efficiently.
In C programming matrix multiplications are done by using arrays, functions, pointers. This detailed explanation will help you to analyze the working mechanism of matrix multiplication and will help to understand how to write code. Step Multiply the first a and second b matrix and store the element in the third matrix c. Matrix multiplication is repeatedly used in programs to represents a graphical data structure, which is used to store multiple vectors and also it is used in many applications like solving linear equations and more.
Lots of research has been done on multiplying matrices using a minimum number of operations. Then you have to declare and define the main function. Then use a print statement to instruct your user for providing or giving input for a number of rows and columns of the first matrix. This is a nested for loop which will take values for "m" number of rows and "n" number of columns, i. Again, use another print statement to instruct your user for providing or giving input for a number of rows and columns of the second matrix.
Same nested loops are used again to feed values to your second array sec[][]. Now the condition is checked whether the number of columns in the first matrix is equal to the number of rows in the second matrix.
If this condition satisfies, you have to write the logic for multiplication.
