please do this.. i have exam tomorrow

#include<stdio.h>
#include<stdlib.h>
int trans(int ,int ,int ,int);
int main()
{
int
m1,m2,mul;
int m,n,i,j,flag=1;
printf("enter range for first matrix");
scanf("%d %d",&m,&n);
m1=(int*)malloc(msizeof(int));
for(i=0;i<m;i++)
{
(m1+i)=(int)malloc(nsizeof(int));
}
if(m!=n)
{
printf("not be orthogonal");
}
else
{
printf("enter element");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
scanf("%d",((m1+i)+j));
}
}
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
(
((m2+j)+i))=(((m1+i)+j));
}
}
mul=trans(m1,m2,m,n);
}
printf("the elements are \n");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
if(i==j&&(
((mul+i)+j))!=1)
flag=0;
if(i!=j&&(
(*(mul+i)+j))!=0)
flag=0;
}
}
if(flag==1)
{
printf("Given Matrix is Orthogonal Matrix\n");
}
else
{
printf("Given Matrix is not an Orthogonal Matrix\n");
}

}

int trans(int m1,int m2,int m,int n)
{
int
p= NULL;
int i,j,sum,k;
p=(int*)malloc(msizeof(int));
for(i=0;i<m;i++)
{
(p+i)=(int)malloc(nsizeof(int));
}
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{sum=0;
for(k=0;k<n;k++)
{
sum=sum+(((m1+i)+k))(((m2+k)+j));
}
(

@mwilki7 well fuck me..... but on a brighter side... i did the diagonal multiplication of two matrix today with double pointer... the logic was ok though.. didn't run ..had some scanf problem.. as its .exe stopped working.. so didn't get the output marks
