#### Program for matrix multiplication using functions

C Program for Matrix Multiplication Using Functions, This below code will help to multiply matrix numbers.

Program Coding
```#include<stdio.h>
int a[3][3],b[3][3],c[3][3],i,j,k;
int m1,m2,n1,n2;
int mul();
int disp();
main()
{
printf("Enter the size of the matrix:");
scanf("%d%d%d%d",&m1,&n1,&m2,&n2);
if(n1==m2)
{
printf("Enter the values for matrix\n");
for(i=0;i<m1;i++)
{
for(j=0;j<m1;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("Enter the values of the matrix B:");
for(i=0;j<m2;j++)
{
for(j=0;j<n2;j++)
{
scanf("%d",&b[i][j]);
}
}
}
mul();
}
int mul()
{
printf("Matrix multiplication is \n");
for(i=0;i<m1;i++)
{
for(j=0;j<n1;j++)
{
For(k=0;k<m2;k++)
{
C[i][j]=c[i][j]+(a[i][k]*b[k][j]);
}
}
}
disp();
}
int disp()
{
for(i=0;i<m1;i++)
{
for(j=0;j<m2;j++)
{
printf("%d",c[i][j]);
}
printf("\n");
}
}
```
