Question

  Write a programusing arrays that will read in an m x n matrix and an   n x p matrix and compute the product the two matrices.      Use a file format similar to that used in the previous    assignment. However, since there are two matrices of two    different dimensions, precede each matrix with its    dimensions.    Notes: -----   - Print the two matrices and their product   - Matrix multiplication is just an extension of the      matrix times vector multiplication of the A6_3*.c      examples. The product will produce additional columns      in the result matrix by repeating the process for every      column in the second matrix.          The result of an (m x n) x (n x p) = (m x p)

#include<stdio.h> int main(){ int a[5][5],b[5][5],c[5][5],i,j,k,sum=0,m,n,o,p; printf(" Enter the row and column of first matrix"); scanf("%d %d",&m,&n); printf(" Enter the row and column of second matrix"); scanf("%d %d",&o,&p); if(n!=o){ printf("Matrix mutiplication is not possible"); printf(" Column of first matrix must be same as row of second matrix"); } else{ printf(" Enter the First matrix->"); for(i=0;i<m;i++) for(j=0;j<n;j++) scanf("%d",&a[i][j]); printf(" Enter the Second matrix->"); for(i=0;i<o;i++) for(j=0;j<p;j++) scanf("%d",&b[i][j]); printf(" The First matrix is "); for(i=0;i<m;i++){ printf(" "); for(j=0;j<n;j++){ printf("%d ",a[i][j]); } } printf(" The Second matrix is "); for(i=0;i<o;i++){ printf(" "); for(j=0;j<p;j++){ printf("%d ",b[i][j]); } } for(i=0;i<m;i++) for(j=0;j<p;j++) c[i][j]=0; for(i=0;i<m;i++){ //row of first matrix for(j=0;j<p;j++){ //column of second matrix sum=0; for(k=0;k<n;k++) sum=sum+a[i][k]*b[k][j]; c[i][j]=sum; } } } printf(" The multiplication of two matrix is "); for(i=0;i<m;i++){ printf(" "); for(j=0;j<p;j++){ printf("%d ",c[i][j]); } } return 0; }
