Here is a C program that accomplishes the task:

void read1(int *a, int m, int n) {
    for(int i=0; i<m; i++) {
        for(int j=0; j<n; j++) {
            scanf("%d", (a + i*n + j));
        }
    }
}

void display(int *a, int m, int n) {
    for(int i=0; i<m; i++) {
        for(int j=0; j<n; j++) {
            printf("%d ", *(a + i*n + j));
        }
        printf("
");
    }
}

void sumOfEachRow(int *a, int m, int n) {
    for(int i=0; i<m; i++) {
        int sum = 0;
        for(int j=0; j<n; j++) {
            sum += *(a + i*n + j);
        }
        printf("Sum of row - %d elements = %d

void sumOfEachColumn(int *a, int m, int n) {
    for(int i=0; i<n; i++) {
        int sum = 0;
        for(int j=0; j<m; j++) {
            sum += *(a + j*n + i);
        }
        printf("Sum of column - %d elements = %d
", i, sum);
    }
}

int main() {
    int m, n;
    printf("Enter row and column sizes : ");
    scanf("%d %d", &m, &n);
    int a[m][n];
    printf("Enter %d elements : ", m*n);
    read1((int *)a, m, n);
    printf("The given matrix is
");
    display((int *)a, m, n);
    sumOfEachRow((int *)a, m, n);
    sumOfEachColumn((int *)a, m, n);
    return 0;
}
```

This program first reads the number of rows and columns from the user. Then it reads the elements of the matrix. It displays the matrix and calculates the sum of each row and each column using pointers.
