Matrix Multiplication in C

Array

Here is the program for matrix multiplication in C. m and n are rows and columns of first matrix. p and q are rows and columns of second matrix. Then, multiplication is possible only if n==p.   Matrix Multiplication in C #include<stdio.h> int main() { int a[5][5],b[5][5],c[5][5],m,n,p,q,i,j,k; printf(“Enter rows and columns of first matrix:”); scanf(“%d%d”,&m,&n); …

C++ Matrix Multiplication Program

Array

Here you will get C++ matrix multiplication program. What we are doing in this program. Read number of rows and columns for two matrix. Then check if matrix multiplication is possible or not. If not possible then show a message to user otherwise multiply them. Finally display the result. C++ Matrix Multiplication Program #include<iostream> using …
