Add operator can be write in macro without type

#define tensorAdd(type,o_C,i_A,i_B)
do{
if(!tensorCheckBroadcasting(i_A,i_B)){
TRACE_LEVEL0("invalid broadcasting");
exit(EXIT_FAILURE);
}else{
int subscript = malloc(o_C->n_dimssizeof(int));
for(int i=0; i<o_C->n_##type##_data; i++){
tensorIdxToSubscript(o_C, subscript, i);
o_C->type##_data[i] = i_A->type##_data[tensorSubscriptToIdx(i_A,subscript)]

}
free(subscript);
}
}while(0)

Would prefer using the stack or pointer instead of a malloc call,
since we wanted to reduce malloc calls in helpers.
What do you think about introducing a macro library for these things?
