additon of 2 matrices error in code

[sekharsomu]

the code is as follows plz tell me where i went wrong and if possible plz explain

#include<stdio.h>
 main()
 {
 int a[10][10],b[10][10],c[10][10],i,j,m,n,p,q;
 printf("input row and column of a matrix:\n");
 scanf("%d%d",&m,&n);
 printf("input row and column of the matrix:\n");
 scanf("%d%d",&p,&q);
 if((m==p)&&(n==q))
 {
 printf("matrices can be added\n");
 printf("input A matrix:\n");
 for(i=0;i<m;++i)
 for(j=0;j<n;++j)
 scanf("%d",&a[i][j]);
 printf("input b matrix:\n");
 for(i=0;i<m;++i)
 for(j=0;j<n;++j)
 scanf("%d",&a[i][j]);
 for(i=0;i<m;++i)
 {
  for(j=0;j< n;++j)
  c[i][j]=0;
  c[i][j]=a[i][j]+b[i][j];
    printf("%5d",c[i][j]);
  printf("\n");
}
}
else
printf("matrices can not be added");
getch();
}

this code is getting executed but end results ie the sum is not as desired

You do two times scanf() into a[][]...

[rasta_freak]

  for(j=0;j< n;++j)
  {
  c[i][j]=0;
  c[i][j]=a[i][j]+b[i][j];
    printf("%5d",c[i][j]);
  }
  printf("\n");

Please learn how to indent code, and fix main to explicitly return an int.

The second one should read into b not a as rasta_freak says.
