function generalization in C

im fairly new to C.

i've written the following code. and all the following functions are nearly identical. i just want to know is there is a way to reduce the following functions into a generic one

struct tensor add(struct tensor t1, struct tensor t2){

    int data[t1.size];

    int i = 0;
    while (i < t1.size) { data[i] = t1.data[i] + t2.data[i]; i++; }

    return Tensor(t1.rank, t1.shape, data);
}

struct tensor sub(struct tensor t1, struct tensor t2){

    int data[t1.size];

    int i = 0;
    while (i < t1.size) { data[i] = t1.data[i] - t2.data[i]; i++; }

    return Tensor(t1.rank, t1.shape, data);
}

struct tensor mul(struct tensor t1, struct tensor t2){

    int data[t1.size];

    int i = 0;
    while (i < t1.size) { data[i] = t1.data[i] * t2.data[i]; i++; }

    return Tensor(t1.rank, t1.shape, data);
}

there are more functions. one for every operator with the following format

struct tensor genericfunc(struct tensor t1, struct tensor t2){

    int data[t1.size];

    int i = 0;
    while (i < t1.size) { data[i] = t1.data[i] ?? t2.data[i]; i++; }

    return Tensor(t1.rank, t1.shape, data);
}

#define definefunc(name, op)                \
Tensor name(Tensor t1, Tensor t2) {         \
    int data[t1.size];                      \
    for (int i = 0; i < t1.size; ++i)       \
       data[i] = t1.data[i] op t2.data[i];  \
                                            \
    return Tensor(t1.rank, t1.shape, data); \
}

definefunc(add, +)
definefunc(sub, -)
definefunc(mul, *)

or

typedef int (*TensorOp)(int, int)

Tensor genericfunc(Tensor t1, Tensor t2, TensorOp op) {
    int data[t1.size];
    for (int i = 0; i < t1.size; ++i)
       data[i] = op(t1.data[i], t2.data[i]);

    return Tensor(t1.rank, t1.shape, data);
}

int TensorOp_add(int a, int b) { return a + b; }
int TensorOp_sub(int a, int b) { return a - b; }
int TensorOp_mul(int a, int b) { return a * b; }

Tensor add(Tensor t1, Tensor t2) { return genericfunc(t1, t2, TensorOp_add); }
Tensor sub(Tensor t1, Tensor t2) { return genericfunc(t1, t2, TensorOp_sub); }
Tensor mul(Tensor t1, Tensor t2) { return genericfunc(t1, t2, TensorOp_mul); }

The above snippets presume the following to avoid using struct everywhere:

typedef struct tensor Tensor;
